My wife found you while looking for TV repair shops in our area. You seem to know your stuff and I now through your knowledge will be able to do the work myself for a fraction of the costs. Thanks mate, I will be following you for any future help.
Thank you for sharing your knowledge about flat screen TV. I salvage mine from the dump and got it up and running again.The rest of the family are quite impressed with their dad.Once again thank you
I can't get enough of watching you videos; I fixed a Samsung by replacing some capacitors for less than $20. Now I am attempting to repair a LG "55 that works sometimes but most of the time I am getting vertical lines. From watching your cool videos, I'm thinking I might need a T com board. I would like more info if possible
I just discovered your channel yesterday after a few hours of googling my problem and watching a few dozen repair videos, and the way you explain things makes me pretty confident that I'll be able to fix my issue after watching some more of your stuff and stripping some more knowledge out of it.. My problem is, I have a red indicator light that turns off when I hit the power button, but there's no sound or picture. And when you press power to turn it back off, nothing happens.. You have to unplug it to get the indicator light again.. Every video I've watched so far, as well as what problems I've read about, none of them are quite the same problem as mine.. And the standard "if it's this or this problem it's probably board A, if it's this or this it's board B, etc" can be used in my case since none of that is my problem. I think I'll have to watch all your videos and try everything until I find it, instead of knowing where to aim and what I'm looking for..
I have Sony Bravia 32"LCD to.Sound &Picture is o.k. But in addition to this,white jig jag lines are appearing day to day in the bottom portion of tv. When I simply power on to tv.the same jig -jag white lines are there. What may be the fault.pl.guide me .
I had an old samsung lcd tv which had no standby voltage. It took me 2 years on and of to get it fixed and understand what I was doing, but it is mainly because of your videos! Great channel! Sometimes I whish you could go a little bit slower and more detailed in the videos. Sometimes it are the small things that are hard to understand. For example, on my powersupply, it was hard to understand the table of the connections going from PSU to MB. On a different tv I had, it didn't even had a table. It would be great if you could go a little more in depth to those small details, and make the videos a little bit slower paced.
Awesome man, thanks. Love the background info on how the logic works and steps you take to start troubleshooting. The bird's eye view of things is forever helpful.
HI Paul Thanks for taking the time to help us out, really leaned something watching your videos, you make it look simple. I'm working on my Samsung 55 inch. Can't seem to find our what's up power board seems fine and steady. But it turns it's self on and off . 4 yrs old. . Keep up the great work.
Our Vizio 50" LED Smart TV lost its picture and sounds a few weeks ago. We were having a hard time finding a place to take for repair other than a best buy, etc which is fine but that would be 65 miles one way just to get it there. We had the very same issue several years ago with another tv and we were able to take into a local repair business and spent $200.00 for the repair plus did without the tv for several weeks. So, it is apparently a common issue and I ran across Tampatec and watched several videos. I went home and took the back off of the tv and sent a picture to my husband asking him to let me know where our tester was...to that I received a reply "damn, ill be right there"! He started fidgeting and messing with fuses and I MADE him knock it off and watch the video step by step and sure enough, it was the main component/logic board. I googled the part number as we didn't want a repair kit and have to solder the small parts but rather replace the entire board. I ordered the part that same afternoon and it was in our mail on Saturday and "we" had the tv working within 15-20 minutes ... all for under $50.00! I am taking credit for this one and rewarded myself appropriately with a glass or 2 of wine! Thank you so much for easy to understand and follow videos...looking for more broken "stuff" to repair! I'm telling everyone I know!!!! ;)
Hey fantastic video! Does it mean that the main logic board should be plugged into the PSU board to have the 12V, 5V or it should appear anyway? My friend gave me his TV's PSU and I thought it was enough like in every device I repair (hobby) it only needs the PSU to supply DC voltage pugged or not! Thank you so much for sharing your knowledge!
Good to find the informative videos. Can’t find the video to take my next step. I have E422VA Vizio tv. Stay is 5.0V. Do not have charting or bulging capacitors. Changed out power board with one from electro parts. No change to TV, still no turn on. Video leads to failed main control board. Received new board from electro parts. Still no turn on. So with new power board and new main board, what do I look at next?
I see the 5 volts but I have NO 12 volts. Would this be the power supply board shot? Hear customer tell me of a wall outlet problem so i am thinking they blew the power supply board. BIG THUMBS UP!
hello, not as fluent in electronics as some, but having a issue with a 55 vizio, led on left bottom of tv comes on for a few seconds then fades out, no picture or sound. I already ordered a power board but not sure if that's the problem, it seemed to have no continuity on one side of the transformer on main board, but this video helped me, and if it' still doesn't work with the power board I ordered i'll make a more educated guess next time
Great info... I'm working on a Vizio E470i-A0. What do you check next if you're getting a voltage for the main board when the on/off button is pressed?
hi tampatec I just subscribed and enjoyed your videos I have a Phillips 55pl9773/17 matchline tv it runs but turns off after a short time about 5 minutes when I turn it on the light is red then goes yellow then green I have pulled the back cover it seems to have very little dust and film on the bulb. the fan is running and is not too bad for lint or dust the screen says to replace bulb and reset the meter could that be what is shutting the tv down after 5 minutes also I don't have the original remote that came with the tv any suggestions on where to get a Phillips oem remote ? thanks for making your videos and helping !
Thanks boss this was good,but I have a vizio model number m3211-a2,the power light comes on and where I press the power button the power light comes on and take it's time and goes off, please tell what to do
Hello Tampatec, Great videos I've learned so much. Hoping you can advise on a problem I'm having with a Vizio D32xD1- Standby light comes on for a second when pluged in powering up I see the power light come on and then goes out no picture. Checking the standby voltage should be 5.2V I'm getting 0V. Unpluging the main board and still 0V standby. Thinking bad powersupply board ordered new and exact same problem no standby voltage.Thoughts?
I have a P series (P702ui-b3) that has no power, it was having a hard time starting for a few weeks where I would have to start it, then shut it down then re start it and it would be fine, then one day it just powered off and now it is dead. My question is, I can have a tech look at it for $50 to isolate the issue and make sure it isnt the light array, and then should I just order the main board, power board and tcon board and swap them out myself, so should I just do the power board and see if that fixes it and if not then get the main board etc..? What do you suggest?
Hallo Mr. TT, great videos help a lot, maybe this time for me?: I've a LG UF656809 blinking 3 times, no Backlight. Only when the left Ribbon from T-con to Panel is removed the Backlight comes on. I tried to Block the Clocktime-Lines, but doesn't work. Mainboard replaced- doesen't work... Do you have an idea? Backlight-short? Tanks a lot
good morning my question is this I have an Emerson TV that will not power on the power light shows up and when I press the power button it blinks and then goes back to solid and the TV will not turn on is it worth fixing or should I just go and invest in a new TV mind you the TV that I'm speaking of is only 2 years old I hope you can help any advice that I can get right now would be greatly appreciated thank you for putting out the videos that you do and I'm very proud subscriber hope to hear from you soon you have a great day
Hi Tampatec. I have a Vizio, model E470I-A0. Originally I lost the picture but had sound. did a flashlight test and could see the menu , etc. After watching many video's I replaced both the power supply board and the main board and it still will not work. In fact i have no sound or video(from another flashlight test). When you power up the tv, the blue power indicator light on the front comes on for a few seconds and then goes out. I have no readings for any standby voltage at the power supply board. I have no readings at all on any pins. I put the old parts back in and it acts the same, no readings at all. I know there is power at the outlet. If you have a moment to read this, any ideas?
Excellent videos. I have a Vizio VO420e and it has the amber light and the white light when I turn it on but no picture or sound. Any ideas if it could be the power supply or main board? Thank you.
I've got a Vizio E50-E3 and the little white light (bottom left) does come on and fade off, as it is supposed to do. Using the flashlight trick I am getting "no se detecto ninguna red", which translated means "no network was detected". When I cycle the inputs, using the buttons on the TV itself, I get that same message on every one. I have tried three different HDMI inputs and the component input(s). Unfortunately, I do not have the actual remote for the TV. I do seem to be getting voltages from the power board to the main board. I am not sure if I am getting all of the ones I am supposed to get, but the pins that have voltages (numbers/amounts) printed on the (power) circuit board are working properly.
hey Tampa tech: I have a new Aquos TV that was sent mounted on an big Octane fitness exercise equipment. It says Aquos on top a d on the bottom of the screen it says Sharp. The mounting plate is right over the SN and model number. My concern is that I have no volume from the TV speakers. It powers on just fine, great picture, I can plug in the headphones and hear it just fine. I want the speakers to work for the rider to work out to. It is new and works as such except the speakers. I think it must be something I'm doing wrong. Do you have any suggestions?
My main board on my vizio e500i-b1 says its supposed to read 24v but I'm only getting 1.5v on all pins.... it would turn on every 10-15 times of trying. What do ya think ?
Hi, I have a vizio m2d460sr TV. Great picture and sound, but the color has gone out. Color on all the menus, Netflix, vudu menus as well, but soon as you play video, connect by hdmi, av, component or stream, its all in black and white. Most sources say main board, but you can hardly find them now and was wondering if you knew what might be wrong so I can fix it? Capacitor, chip cable or board?
Hi Tampatec. I have a Vizio V555g1. Back lights work, I replaced the T-Con and main board and still have no picture and no sound. Could it be the power board or the ribbon connector? I am just north of Tampa. Could use advice.
Hello, I'm working on a 55" Element that turns on and has backlight but no picture. This model does not have a separate t-con board. There's a ribbon cable which connects from the main board to the buffer board at the bottom of the panel. I've tried 3 different main boards and no change. Is there a good way to test the buffer boards? I'm at a loss here.
Fantastic video thanks for charing. Question: what is the 12volts below pin 13? I have a vizio tv 32in and that 12v is zero even if i try to turn on the tv. Does it means that the logic board is bad and i need to replace it? I have no power in my tv but just the front vizio logo is orange but not image. I hope you have respond my questions. Many thanks
I have a Vizio M470NV that turns on to a yellow vizio light below the display and nothing else. No video or sound. All the boards look clean with no burnt spot and no bulging capacitors. I replaced the power supply, $50, with no change. Per one of your videos, I disconnected the ribbon from the main board to the remote sensor board, with no change. To replace daughter board or any of the little boards aren’t expensive. The main board repair services cost around $100 or to replace it cost more than the tv is worth. How do I troubleshoot the boards, suggestion?
Nice vid. Just got a vizio jv50p and thanks to ur vid i noticed some caps are bad. I just ordered them but noticed when the screen does finally come i have no sound could it be one of the caps or a different area
Hi, This was a very helpful video. Thanks for sharing it. What do you think of the reliability and quality of off name TV brands (like Westinghouse, RCA, Seiki and so forth) as compared to main stream TV names like Samsung, LG, Sharp, Panasonic, etc? Thanks a lot, Tom
Hey Tampatec - I have a Vizio sv471xvt . We were watching tv when the picture suddenly went black, audio is fine. Plugged and unplugged tv to reset. Standby light is on, logo glows orange and changes to white when powered on. Sound is fine from all inputs. No picture from any input. Tried flashlight test and I can see proper images. (guessed it was the backlight inverter board from your great troubleshooting vids).I tried to get the backlight inverter board from shopjimmy and vizparts but no luck because of the age of the tv. Do I give up and throw the TV away? Help...
I have a JVC LT-46AM73 that just stopped having picture or sound one day for no reason. I have standby red light and when I turn the power on (button or remote) the light turns green, but still no picture or sound. I have watched several of your videos (which are wonderful) but the connections on this TV's boards are so different, I can't tell what I'm suppose to be checking. Any thoughts?
I have a smilar Vizio - a SV420M. I've done the troubleshooting but not sure what fix is needed. Problem started when TV would not take any commands from remotes. Still worked from onboard controls. Now it will not turn on. I get the orange standby light, after pressing power on tv, the light turns white for a bit, then fades to nothing. Power board has 5.2V steady. Pressing the power button returns 2.2V back to the power board. The 12V terminals on power board only show negative millivolts at all times. These are not the exact symptoms mentioned on Shop Jimmy for EPROM fix. What else can I test to be sure? Thank you.
Hey Tampatec, Absolutely love your info and recommend you to all. I would like to ask you a question before throwing out my TV. Everything is working on my Visio sv47xvt, except the backlight. Because it's so old how do I find parts or find the problem - the backlight inverter appears to be part of a larger board. Thank you in advance!
I have a 47" Vizio Lightning came through my telephone line and blew my modem up and I had my TV connected with a Ethernet cable (it is a smart TV)and travel on into my TV after that my TV does not show a screen or have Audio. The Vizio light on the front will come on when turn on but that's it.Got any advice on what my problem may be? I want to get it fixedso bad as it is only 3 yrs old and was the last thing my dad helped me get before he passed away.It is my first flat screen and my dad helped me shop and buy it so am not throwing it out even if it just sits somewhere I can't throw it out. Please help?
Hello, really so often that eprom/bios memory need to be changed (only after a few years) ... When on a monocard, I see "on/off on 4 points like test points , (2 each side) on the circuit board, are they here to check if some tension appears, or may I shorten those '2 by 2 ?) to force startup of alim ? Samsung (43NU7025K) no much writings on the board, no service manual find ! Thank you I had no success on that board that was in need of new eprom probably/ (most tensions present bu no start of the alim, only standby voltages) while replacing condensators and mosfets, I did damage a via and did loose a signal connection probably. Cannot trace it and repair ...
I have a LG 47LW6500-UA, my problem is no picture and no sound. I power it on i hear it clicking on and the front buttons scroll across normally indicating power, as well as the red standby light turning to solid white, but can't do anything else, no volume, menu or input changes through the remote or directly on the tv. I've looked with a flashlight to see any images to no avail. I also looked for any blown capacitors but everything looks fine. I'm trying to determine what board it is and could use a little more detailed help. Since every place I've looked for any of replacement parts are out of stock, i'm kind of stuck. I also don't want to try the oven trick unless I've determined that it is in fact my main board and not something else. Any suggestions or advice would be greatly appreciated.
Lc65le654u no power. When first recived this tv I had a light blue standby light. Unplugged power removed left side ribbon cable to the t-con board and now no standby light showing. Reset everything back to where it was and checked voltages. Getting all led power 86v. As far as voltages to mainboard pins 1,2,3 19 volts4,5,6 ground pins 7,8 0 volts pin 9-ps on 0v pin 10 0 volts. Checked main board caps getting different readings with same cap values 220uf 25v
Hi again tampatec, I watched so many video's but didn't see this one! after running the same test you did in the video, I've seen I have 4.53 volts to the ON/OFF wire when in standby, and 0 volts when I hit the power button. That makes me think it's definitly a problem with my main power board like you said in the video. The only problem is I looked up the serial number on shopjimmy (i found the sticker on the back silly me) and it seems they don't have the part. 55120RE01M3393LNA5-A1 is the serial number, but shopjimmy has neither the board or the eprom repair kit. What can I do? Also just to be sure would you agree given the symptoms (pasted from my previous comment below) that it's probably a problem with the main logic board?? Thanks, I'm really hoping I can repair this TV, i'm a student and money is tight, lol TV symptoms My TV screen is black, though I do have a red light on the bottom, and I have no audio. I've tried your flashlight test and see nothing when I try to bring up the menu screen, and do not see any glow from the LED back lights when I turn off the lights. However, the TV did flash once when I was messing with it. I've also checked the power supply and do have standby power when its off at 5 volts, but 0 volts when I turn the power on. I also checked the keypad/menu button panel on the tv and it's reading 3.32 volts to the main logic board and the volts fluctuate when I hit the power button so I think that's good as well.
Here's a problem posted by another user many years ago which is exactly like what I am seeing on my LC-52D62U. Any ideas on what may be causing this? If it is one of the PWBs are they available from Sharp? Thank you.
Hey Tampatec, I have a Sharp Aquos LC45GX6U. It has picture when plugged into my computer, but the screen is really bright and there is no menu button on the monitor to access features. Also when the monitor isn't plugged into anything and I power it on, I get a bright white screen. I'm assuming it's the backlight malfunctioning, but is there any easy fix or could you tell me what board I need to replace if that is necessary. Any information you can give me would be much appreciated. A video tutorial on white screens would be great too. Also I subscribed and liked, very informative and straight forward videos you have. Thank you.
I am having issues with a m65c1 vizio I just acquired from my aunt. I have steady standby power, at 5 volts. 24 volts to the LED from power supply board, I have 19 volts on every pin labeled 12 volt at power supply board. Which I find odd, but I have seen others online with the same results. But, the power on signal voltage from the main board is only at a steady .15 volts... And the main board will not power off with the switch or remote, dim red LED indicator remains illuminated, and the main board gets warm as well. Would you say this is a main board issue? Did the flash light test as well, and nothing. No signs of caps bursting or swollen.
Hello, your videos are helpful and easy to understand, thanks for sharing your knowledge. I was wondering about an issue with my mothers TV, an LG 42". The problem is with the picture, it will be crystal clear for 3 seconds, then goes fuzzy/distorted for 3 seconds, back and forth. Any ideas on how to troubleshoot this issue? I have tried to look it up, maybe I'm not wording my search right, but I have had no luck finding any useful information. Thanks again for your great videos
Hi I have a Vizio p55 c1 I have sound and back lights but no picture. I replaced the t-con... still no pictures... where should I go from here? This unit has 4 led drivers FYI.
Hello Tampatec,I have a Vizio 60 inch E600I b3 I bought new parts and put the in and when turn on the TV the screen just show blue no Vizio logo or menu. Please help Thanks!
Help please, 42" vizio Works fine and that shuts off after about 10 minutes. It has standby voltage and 12 V when turned on and when it works there's 380 V across the big capacitor but it goes to 0v when the TV goes out
I have a Vizio. P702ui-b3. Went totally dead. No power. No lights. Nothing. Checked voltages on power board. Seem fine. But the plug that is connected to the main board should have 12 volts. It’s has 4 volts. When I unplug the main board from the power board. The voltage changes to 12 volts like it should. Any suggestions?
Hello, I have a JVC LT-42X688. The screen turns on...the JVC Logo appears, than after 5 seconds the screen goes black. I replaced the 2 invertor boards and the T con board which did not correct the issue. There are 3 additional boards..the main Power Board,signal board and a tuner board....any idea?
Tampatec ive a phillips 47" lcd tv that bootloops when turned on. there were a couple of swollen caps on power supply which i replaced but still boot looping, all voltages are present exept for the 12v which seems to be measuring 4.5v?? checked 12v regulator and i think it was ok from what i remember? now should i replace power board or should i be looking towards main board? or does this problem sound familiar to you? Any help would be great. Thanks
Hey tampatec, I have a LG tv that has pins on the power board labeled with 3.5v, 12v, and 20v, and they all show the appropriate power. I have no picture, but my standby is on when the TV is plugged in. Any ideas? thsnks!
I really need your help... We had a lightning strike hit the apartment and now my TV doesn't work. I replaced the power board and LED driver but the screen never turns on. Have any guesses???
Hey TampaTech I live local in TPA also and have a 55 55l260A13 , it hit and miss with the power on so I believe it's the supply wondering how much it would be to fix if I get my own part ??
Hey man, hope you can help me. I have a problem with my Led Tv, the picture suddenly turned purple and it started to shake. There's nothing wrong with the cable. Do you have any idea what might be wrong with it?
I have a Vizio P 65", Model:P65-F1, and I am getting a gray screen. I do see backlights, but no picture is displayed, and I did have sound. Any ideas??
I have a Samsung UN46EH5000FXZA UD03 , no power, has standby light on and there is a red light on some part on the main board. I have replaced the power board and main board, still does the same. What now?
Hi Tampatec I have a Samsung T240HD, i"m getting a bunch of bright red and purple dots in the center of the screen almost looks rashlike. Have you seen this before and if so what's causing it. Thanks.
I have two TV's of the same model number. I bought the second one for parts only to find out they are two totally different TV's; every part is different. So, I couldn't swap a single thing (the power board) (excluding any frame or the chassis, I presume).
I have an Emerson LCD flat screen. I have sound but no picture. My backlights come on for 10 sec then go off. I did the flashlight test on the screen and I can see AV1 on the screen. What boards would I need to replace to fix this?
I'm having an odd issue with my Vizio M49-C1. Within an hour after turning it on, it will reset itself... turning off and then back on. Usually after that it will be fine for hours without resetting again, though I think it has done it a couple times in a night before. I've also had issues where it wouldn't switch between inputs. The input selector would come up on the screen, but when I selected a different input (Xbox One) it kept going back to the original input (PS4). Once I turned off the PS4 I was finally able to switch to the Xbox. Finally, one night I came home, turned it on using the button on the set, and then neither the remote nor the buttons on the TV itself would respond. I had to unplug it to reset it. Considering the symptoms I'm thinking it may be the main board, but it's really difficult to diagnose when the issues are intermittent. Anyone have these issues before?
Hey tampatec, i have an lg60ln5400, its ok except for a 3” strip of lowered color as the reat of screen, i changed t- con- no change- i have pics, if intrrested

Have Sharp Aquos LC 60LE831U will not power up. No stand by voltage. Have not been able to find a psb. Checked Shop Jimmy, Amazon, even Sharp. Found bad diode and will replace this in the mean time but in case this doesn't work, can you suggest anyone else I could find a Delta DPS-183BP A. Rev S4?Thanks
Hi. The power went out completely on my Vizio VX32L when I connected it to the computer. I had both the tv and the computer powered off when I made the connection. When I turned back on, tv was dead, no power. I ordered a new power supply board and replaced it. It still doesn't work. Before I do anything with the mainboard, I am wondering if that could even be the problem. I will try the tests with a multi-meter, but I wonder if the computer aspect has any significance.
Hello Tampatec! Huge fan of your work and videos, they have been a great help with a great many television repairs. My question is regarding a Vizio 47" LED tv. The backlight voltage starts at 128v and drops to 66v, regardless whether or not the backlights are plugged in. I get the same voltage and drop with them plugged in or not plugged in. Does this mean there is a power supply issue or a bad led strip(s)?
Eddie Mays can be bad LED strip but use the service manual to find out the running voltage for the LED backlight. I find that if the backlight settings were set to max or too High usually it's the LED strips.
Thank you very much for your reply! Well, if I had the service manual, I would def. take that advise, sadly I do not have it. I only have access to the User Guide. It's a Vizio LED E470i-A0.
I have a vizio d40-d1 I got black screen with no backlights and the indicator light does not come on, I replaced the power supply board to no prevail. What else could it be?

Hi there I really need help on a P65-E1, everything works I have an image on the screen , plays videos , have audio, but the image is split in half then filled in with a full picture image, its difficult to explain ,plz
Hey there, Umm I asked a Q too but this video is 2 years old or more, and it doesnt seem like anyone is answering these anymore sadly. You can poke around shop jimmys and other parts companies that offer some diagnoses, they might be able to help, I ended up taking my tv to a tech for a free estimate, if you have a local guy who will look at it for free it might be worth that too, good luck.
HI QUESTION MAYBE YOU CAN HELP ME OUT MY QUESTION IS MY TV THE E371VA VIZIO LOGO TURNS ON THEN 1 SECOND LATER IT TURNS DIM AND STAYS DIM SOMETIMES I HAVE TO WAIT A COUPLE OF HRS THEN THE VIZO LOGO TURNS BRIGHT AND TV TURNS ON AND WORKS FINE AND THEN THE NEXT DAY I GO THROUGH THE SAME THING.
I have Un55js9000fxza, since I got tv, there was no picture. At one time, it displayed the menu app, and all display was shaking then later it all disappeared. Since then, I've been getting bluish screen, no samsung logo and no picture. Occasionally, I'll hear the led driver board buzzing on low tone- dont know if it's normal. Also when I connect the one box to the main board, the screen will look like there was change scene and went back back to blue screen. I recently replaced the T con and there is no changes. Please help
I have a vizio e60-e3 that will flash the vizio logo on the screen for a split second when the the power button is pushed. Then that's it nothing else. Any idea of what it could be or what to look for?
Freegeek gets tv's that are bad or unneeded. That saying, I volunteer at Freegeek Arkansas. I have taken the bad LCD screens from the Visio tv's, to use the LED light panel but the Tv shuts down after about 15 min. what can we do to bypass or fix the auto shut down
Eddie Laureano Jun 27, 2020, 6:17 PM CDT Hello I need help with my M65-D0 I had a lightning storm issue and my TV when out. No display or status light in the lower left. I google and UA-cam videos on checking out and I thought I had a bad power supply board. I got the board and installed and the old board and the new board did the same thing with the clicking of the relay in the board. Then I continued to check again and I was able to find the the 5 volt signal from the main board was not coming in to the power supply. Then I ordered the main board today I get the board and installed. I powered on and I hear the click and the status light in the lower left turns on but it shuts off again and tried to start again. I have connected the HDMI in to multiple outlets and nothing. I have looked at you videos and the last 2 board are the t con and the LED driver board. But I really would like help in narrowing it down. I don't see any led from the back... or no sound that I can get. Please help.
Hi, I have uniform horizontal lines across the entire screen, coupled with some vertical red lines on on about 2/3 of the screen. The vertical lines are brightness on the left side and gets progressively lighter as you go towards the right side of the screen. My tv is a Samsung Model # un55c7100wfxza, version sq01, type# un55c7100. Any help will be appreciated. Thanks. David
have you ever seen where an x-box 360 can cause the back lights to go out? like a short? first tv was my seiki, 2nd one a samsung. my seiki still does not work even without the xbox system hooked up. thanks
Steve Garrett if there is voltage feedback from a bad Xbox video port or bad hdmi cable it's more likely main board would go out first because hdmi cable is directly connected to that board. unless you have a bad AC outlet causing your tv to go bad. also maxing out backlight brightness to 100% will cause it to go out too. hope that helps
My wife found you while looking for TV repair shops in our area. You seem to know your stuff and I now through your knowledge will be able to do the work myself for a fraction of the costs. Thanks mate, I will be following you for any future help.
Thank you for sharing your knowledge about flat screen TV. I salvage mine from the dump and got it up and running again.The rest of the family are quite impressed with their dad.Once again thank you
I can't get enough of watching you videos; I fixed a Samsung by replacing some capacitors for less than $20. Now I am attempting to repair a LG "55 that works sometimes but most of the time I am getting vertical lines. From watching your cool videos, I'm thinking I might need a T com board. I would like more info if possible
I just discovered your channel yesterday after a few hours of googling my problem and watching a few dozen repair videos, and the way you explain things makes me pretty confident that I'll be able to fix my issue after watching some more of your stuff and stripping some more knowledge out of it..
My problem is, I have a red indicator light that turns off when I hit the power button, but there's no sound or picture. And when you press power to turn it back off, nothing happens.. You have to unplug it to get the indicator light again..
Every video I've watched so far, as well as what problems I've read about, none of them are quite the same problem as mine.. And the standard "if it's this or this problem it's probably board A, if it's this or this it's board B, etc" can be used in my case since none of that is my problem. I think I'll have to watch all your videos and try everything until I find it, instead of knowing where to aim and what I'm looking for..
Soulife check standby volts going to main board.
Hey Tampatec, just wanted to let you know that I really appreciate your posts and I've learned a lot.. Thank you!
fixed my tv last week. replaced bad caps on mainboard and replaced tcon board. never soldered or desoldered a thing before in my life.
I have Sony Bravia 32"LCD to.Sound &Picture is o.k. But in addition to this,white jig jag lines are appearing day to day in the bottom portion of tv. When I simply power on to tv.the same jig -jag white lines are there. What may be the fault.pl.guide me .
Fixed my 70 inch vizio today with 1$ diode, thanks to your vids..Thanks so much
Cool, what board power board or main board?
I had an old samsung lcd tv which had no standby voltage. It took me 2 years on and of to get it fixed and understand what I was doing, but it is mainly because of your videos! Great channel! Sometimes I whish you could go a little bit slower and more detailed in the videos. Sometimes it are the small things that are hard to understand. For example, on my powersupply, it was hard to understand the table of the connections going from PSU to MB. On a different tv I had, it didn't even had a table. It would be great if you could go a little more in depth to those small details, and make the videos a little bit slower paced.
Awesome man, thanks. Love the background info on how the logic works and steps you take to start troubleshooting. The bird's eye view of things is forever helpful.
HI Paul
Thanks for taking the time to help us out, really leaned something watching your videos, you make it look simple.
I'm working on my Samsung 55 inch. Can't seem to find our what's up power board seems fine and steady. But it turns it's self on and off . 4 yrs old. .
Keep up the great work.
Our Vizio 50" LED Smart TV lost its picture and sounds a few weeks ago. We were having a hard time finding a place to take for repair other than a best buy, etc which is fine but that would be 65 miles one way just to get it there. We had the very same issue several years ago with another tv and we were able to take into a local repair business and spent $200.00 for the repair plus did without the tv for several weeks. So, it is apparently a common issue and I ran across Tampatec and watched several videos. I went home and took the back off of the tv and sent a picture to my husband asking him to let me know where our tester was...to that I received a reply "damn, ill be right there"! He started fidgeting and messing with fuses and I MADE him knock it off and watch the video step by step and sure enough, it was the main component/logic board. I googled the part number as we didn't want a repair kit and have to solder the small parts but rather replace the entire board. I ordered the part that same afternoon and it was in our mail on Saturday and "we" had the tv working within 15-20 minutes ... all for under $50.00! I am taking credit for this one and rewarded myself appropriately with a glass or 2 of wine! Thank you so much for easy to understand and follow videos...looking for more broken "stuff" to repair! I'm telling everyone I know!!!! ;)
Hey fantastic video! Does it mean that the main logic board should be plugged into the PSU board to have the 12V, 5V or it should appear anyway? My friend gave me his TV's PSU and I thought it was enough like in every device I repair (hobby) it only needs the PSU to supply DC voltage pugged or not! Thank you so much for sharing your knowledge!
Great informative video!!! Short, sweet, and concise! The best I've seen!
You are a good instructor Tampatec..Hands down to you!
Good to find the informative videos. Can’t find the video to take my next step. I have E422VA Vizio tv. Stay is 5.0V. Do not have charting or bulging capacitors. Changed out power board with one from electro parts. No change to TV, still no turn on. Video leads to failed main control board. Received new board from electro parts. Still no turn on. So with new power board and new main board, what do I look at next?
Wish I'd seen your video's before I threw my Vizo out.. Your videos will help me in the future so all not lost. Good Job
Great info. I have a E65inch Vizio that has audio but picture goers off and on every 2 second. Is it a capacitor problem. Thank you in advance
I see the 5 volts but I have NO 12 volts. Would this be the power supply board shot? Hear customer tell me of a wall outlet problem so i am thinking they blew the power supply board. BIG THUMBS UP!
hello, not as fluent in electronics as some, but having a issue with a 55 vizio, led on left bottom of tv comes on for a few seconds then fades out, no picture or sound. I already ordered a power board but not sure if that's the problem, it seemed to have no continuity on one side of the transformer on main board, but this video helped me, and if it' still doesn't work with the power board I ordered i'll make a more educated guess next time
Great info... I'm working on a Vizio E470i-A0. What do you check next if you're getting a voltage for the main board when the on/off button is pressed?
hi tampatec I just subscribed and enjoyed your videos I have a Phillips 55pl9773/17 matchline tv it runs but turns off after a short time about 5 minutes when I turn it on the light is red then goes yellow then green I have pulled the back cover it seems to have very little dust and film on the bulb. the fan is running and is not too bad for lint or dust the screen says to replace bulb and reset the meter could that be what is shutting the tv down after 5 minutes also I don't have the original remote that came with the tv any suggestions on where to get a Phillips oem remote ? thanks for making your videos and helping !
Thanks boss this was good,but I have a vizio model number m3211-a2,the power light comes on and where I press the power button the power light comes on and take it's time and goes off, please tell what to do
Hello Tampatec, Great videos I've learned so much. Hoping you can advise on a problem I'm having with a Vizio D32xD1- Standby light comes on for a second when pluged in powering up I see the power light come on and then goes out no picture. Checking the standby voltage should be 5.2V I'm getting 0V. Unpluging the main board and still 0V standby. Thinking bad powersupply board ordered new and exact same problem no standby voltage.Thoughts?
I have a P series (P702ui-b3) that has no power, it was having a hard time starting for a few weeks where I would have to start it, then shut it down then re start it and it would be fine, then one day it just powered off and now it is dead.
My question is, I can have a tech look at it for $50 to isolate the issue and make sure it isnt the light array, and then should I just order the main board, power board and tcon board and swap them out myself, so should I just do the power board and see if that fixes it and if not then get the main board etc..?
What do you suggest?
Hallo Mr. TT, great videos help a lot, maybe this time for me?: I've a LG UF656809 blinking 3 times, no Backlight. Only when the left Ribbon from T-con to Panel is removed the Backlight comes on. I tried to Block the Clocktime-Lines, but doesn't work. Mainboard replaced- doesen't work... Do you have an idea? Backlight-short? Tanks a lot
good morning my question is this I have an Emerson TV that will not power on the power light shows up and when I press the power button it blinks and then goes back to solid and the TV will not turn on is it worth fixing or should I just go and invest in a new TV mind you the TV that I'm speaking of is only 2 years old I hope you can help any advice that I can get right now would be greatly appreciated thank you for putting out the videos that you do and I'm very proud subscriber hope to hear from you soon you have a great day
Hi Tampatec. I have a Vizio, model E470I-A0. Originally I lost the picture but had sound. did a flashlight test and could see the menu , etc. After watching many video's I replaced both the power supply board and the main board and it still will not work. In fact i have no sound or video(from another flashlight test). When you power up the tv, the blue power indicator light on the front comes on for a few seconds and then goes out. I have no readings for any standby voltage at the power supply board. I have no readings at all on any pins. I put the old parts back in and it acts the same, no readings at all. I know there is power at the outlet. If you have a moment to read this, any ideas?
Excellent videos. I have a Vizio VO420e and it has the amber light and the white light when I turn it on but no picture or sound. Any ideas if it could be the power supply or main board? Thank you.
I've got a Vizio E50-E3 and the little white light (bottom left) does come on and fade off, as it is supposed to do.
Using the flashlight trick I am getting "no se detecto ninguna red", which translated means "no network was detected".
When I cycle the inputs, using the buttons on the TV itself, I get that same message on every one. I have tried three different HDMI inputs and the component input(s).
Unfortunately, I do not have the actual remote for the TV.
I do seem to be getting voltages from the power board to the main board. I am not sure if I am getting all of the ones I am supposed to get, but the pins that have voltages (numbers/amounts) printed on the (power) circuit board are working properly.
Do you have any videos on broken screen on Sony KDL60W850B? We have lines with a grey at the bottom of the lines
hey Tampa tech: I have a new Aquos TV that was sent mounted on an big Octane fitness exercise equipment. It says Aquos on top a d on the bottom of the screen it says Sharp. The mounting plate is right over the SN and model number. My concern is that I have no volume from the TV speakers. It powers on just fine, great picture, I can plug in the headphones and hear it just fine. I want the speakers to work for the rider to work out to. It is new and works as such except the speakers. I think it must be something I'm doing wrong. Do you have any suggestions?
My main board on my vizio e500i-b1 says its supposed to read 24v but I'm only getting 1.5v on all pins.... it would turn on every 10-15 times of trying. What do ya think ?
Hi, I have a vizio m2d460sr TV. Great picture and sound, but the color has gone out. Color on all the menus, Netflix, vudu menus as well, but soon as you play video, connect by hdmi, av, component or stream, its all in black and white. Most sources say main board, but you can hardly find them now and was wondering if you knew what might be wrong so I can fix it? Capacitor, chip cable or board?
Hi Tampatec. I have a Vizio V555g1. Back lights work, I replaced the T-Con and main board and still have no picture and no sound. Could it be the power board or the ribbon connector? I am just north of Tampa. Could use advice.
Hello, I'm working on a 55" Element that turns on and has backlight but no picture. This model does not have a separate t-con board. There's a ribbon cable which connects from the main board to the buffer board at the bottom of the panel. I've tried 3 different main boards and no change. Is there a good way to test the buffer boards? I'm at a loss here.
Fantastic video thanks for charing. Question: what is the 12volts below pin 13? I have a vizio tv 32in and that 12v is zero even if i try to turn on the tv. Does it means that the logic board is bad and i need to replace it? I have no power in my tv but just the front vizio logo is orange but not image. I hope you have respond my questions. Many thanks
I have a Vizio M470NV that turns on to a yellow vizio light below the display and nothing else. No video or sound. All the boards look clean with no burnt spot and no bulging capacitors. I replaced the power supply, $50, with no change. Per one of your videos, I disconnected the ribbon from the main board to the remote sensor board, with no change. To replace daughter board or any of the little boards aren’t expensive. The main board repair services cost around $100 or to replace it cost more than the tv is worth. How do I troubleshoot the boards, suggestion?
Dude i came from your part 2 video. It was friggin hard to find part one. There is no link from part 2?? You told me to come here! Lol
Fyi :)
Nice vid. Just got a vizio jv50p and thanks to ur vid i noticed some caps are bad. I just ordered them but noticed when the screen does finally come i have no sound could it be one of the caps or a different area
Hi,
This was a very helpful video. Thanks for sharing it.
What do you think of the reliability and quality of off name TV brands (like Westinghouse, RCA, Seiki and so forth) as compared to main stream TV names like Samsung, LG, Sharp, Panasonic, etc?
Thanks a lot, Tom
Hey Tampatec - I have a Vizio sv471xvt . We were watching tv when the picture suddenly went black, audio is fine. Plugged and unplugged tv to reset. Standby light is on, logo glows orange and changes to white when powered on. Sound is fine from all inputs. No picture from any input. Tried flashlight test and I can see proper images. (guessed it was the backlight inverter board from your great troubleshooting vids).I tried to get the backlight inverter board from shopjimmy and vizparts but no luck because of the age of the tv. Do I give up and throw the TV away? Help...
I have a JVC LT-46AM73 that just stopped having picture or sound one day for no reason. I have standby red light and when I turn the power on (button or remote) the light turns green, but still no picture or sound. I have watched several of your videos (which are wonderful) but the connections on this TV's boards are so different, I can't tell what I'm suppose to be checking. Any thoughts?
I have a smilar Vizio - a SV420M. I've done the troubleshooting but not sure what fix is needed. Problem started when TV would not take any commands from remotes. Still worked from onboard controls. Now it will not turn on. I get the orange standby light, after pressing power on tv, the light turns white for a bit, then fades to nothing. Power board has 5.2V steady. Pressing the power button returns 2.2V back to the power board. The 12V terminals on power board only show negative millivolts at all times. These are not the exact symptoms mentioned on Shop Jimmy for EPROM fix. What else can I test to be sure? Thank you.
Will backlight output come on if main brain isn't hooked up? This tv only has backlight and output connectors to main brain.
Hi
Can you tell me what s6 and d6 also d8 and s8 mean on the panel tester. Your reply would be much appreciated
Thanks John
Hey Tampatec, Absolutely love your info and recommend you to all. I would like to ask you a question before throwing out my TV. Everything is working on my Visio sv47xvt, except the backlight. Because it's so old how do I find parts or find the problem - the backlight inverter appears to be part of a larger board. Thank you in advance!
I have a 47" Vizio Lightning came through my telephone line and blew my modem up and I had my TV connected with a Ethernet cable (it is a smart TV)and travel on into my TV after that my TV does not show a screen or have Audio. The Vizio light on the front will come on when turn on but that's it.Got any advice on what my problem may be? I want to get it fixedso bad as it is only 3 yrs old and was the last thing my dad helped me get before he passed away.It is my first flat screen and my dad helped me shop and buy it so am not throwing it out even if it just sits somewhere I can't throw it out. Please help?
Hello, really so often that eprom/bios memory need to be changed (only after a few years) ... When on a monocard, I see "on/off on 4 points like test points , (2 each side) on the circuit board, are they here to check if some tension appears, or may I shorten those '2 by 2 ?) to force startup of alim ? Samsung (43NU7025K) no much writings on the board, no service manual find ! Thank you
I had no success on that board that was in need of new eprom probably/ (most tensions present bu no start of the alim, only standby voltages) while replacing condensators and mosfets, I did damage a via and did loose a signal connection probably. Cannot trace it and repair ...
Hi. how can I repair my TV. the model number is L65E5500FS ,TCL 4K smart TV, I really enjoyed the way you explain things. Thanks,
Khamis, Australia.
I have a LG 47LW6500-UA, my problem is no picture and no sound. I power it on i hear it clicking on and the front buttons scroll across normally indicating power, as well as the red standby light turning to solid white, but can't do anything else, no volume, menu or input changes through the remote or directly on the tv. I've looked with a flashlight to see any images to no avail. I also looked for any blown capacitors but everything looks fine. I'm trying to determine what board it is and could use a little more detailed help. Since every place I've looked for any of replacement parts are out of stock, i'm kind of stuck. I also don't want to try the oven trick unless I've determined that it is in fact my main board and not something else. Any suggestions or advice would be greatly appreciated.
My fluke is 40 years old and still working fine.
Lc65le654u no power. When first recived this tv I had a light blue standby light. Unplugged power removed left side ribbon cable to the t-con board and now no standby light showing. Reset everything back to where it was and checked voltages. Getting all led power 86v. As far as voltages to mainboard pins 1,2,3 19 volts4,5,6 ground pins 7,8 0 volts pin 9-ps on 0v pin 10 0 volts. Checked main board caps getting different readings with same cap values 220uf 25v
Hi again tampatec,
I watched so many video's but didn't see this one! after running the same test you did in the video, I've seen I have 4.53 volts to the ON/OFF wire when in standby, and 0 volts when I hit the power button. That makes me think it's definitly a problem with my main power board like you said in the video. The only problem is I looked up the serial number on shopjimmy (i found the sticker on the back silly me) and it seems they don't have the part. 55120RE01M3393LNA5-A1 is the serial number, but shopjimmy has neither the board or the eprom repair kit. What can I do? Also just to be sure would you agree given the symptoms (pasted from my previous comment below) that it's probably a problem with the main logic board?? Thanks, I'm really hoping I can repair this TV, i'm a student and money is tight, lol
TV symptoms
My TV screen is black, though I do have a red light on the bottom, and I have no audio. I've tried your flashlight test and see nothing when I try to bring up the menu screen, and do not see any glow from the LED back lights when I turn off the lights. However, the TV did flash once when I was messing with it. I've also checked the power supply and do have standby power when its off at 5 volts, but 0 volts when I turn the power on. I also checked the keypad/menu button panel on the tv and it's reading 3.32 volts to the main logic board and the volts fluctuate when I hit the power button so I think that's good as well.
Here's a problem posted by another user many years ago which is exactly like what I am seeing on my LC-52D62U. Any ideas on what may be causing this? If it is one of the PWBs are they available from Sharp? Thank you.
Hey Tampatec, I have a Sharp Aquos LC45GX6U. It has picture when plugged into my computer, but the screen is really bright and there is no menu button on the monitor to access features. Also when the monitor isn't plugged into anything and I power it on, I get a bright white screen. I'm assuming it's the backlight malfunctioning, but is there any easy fix or could you tell me what board I need to replace if that is necessary. Any information you can give me would be much appreciated. A video tutorial on white screens would be great too. Also I subscribed and liked, very informative and straight forward videos you have. Thank you.
I am having issues with a m65c1 vizio I just acquired from my aunt. I have steady standby power, at 5 volts. 24 volts to the LED from power supply board, I have 19 volts on every pin labeled 12 volt at power supply board. Which I find odd, but I have seen others online with the same results. But, the power on signal voltage from the main board is only at a steady .15 volts... And the main board will not power off with the switch or remote, dim red LED indicator remains illuminated, and the main board gets warm as well. Would you say this is a main board issue? Did the flash light test as well, and nothing. No signs of caps bursting or swollen.
Hello, your videos are helpful and easy to understand, thanks for sharing your knowledge.
I was wondering about an issue with my mothers TV, an LG 42".
The problem is with the picture, it will be crystal clear for 3 seconds, then goes fuzzy/distorted for 3 seconds, back and forth. Any ideas on how to troubleshoot this issue? I have tried to look it up, maybe I'm not wording my search right, but I have had no luck finding any useful information. Thanks again for your great videos
Bro this guy doesnt answer?
Hi I have a Vizio p55 c1 I have sound and back lights but no picture. I replaced the t-con... still no pictures... where should I go from here? This unit has 4 led drivers FYI.
Hello Tampatec,I have a Vizio 60 inch E600I b3 I bought new parts and put the in and when turn on the TV the screen just show blue no Vizio logo or menu. Please help Thanks!
Help please, 42" vizio Works fine and that shuts off after about 10 minutes. It has standby voltage and 12 V when turned on and when it works there's 380 V across the big capacitor but it goes to 0v when the TV goes out
I have a Vizio. P702ui-b3. Went totally dead. No power. No lights. Nothing. Checked voltages on power board. Seem fine. But the plug that is connected to the main board should have 12 volts. It’s has 4 volts. When I unplug the main board from the power board. The voltage changes to 12 volts like it should. Any suggestions?
Hello, I have a JVC LT-42X688. The screen turns on...the JVC Logo appears, than after 5 seconds the screen goes black. I replaced the 2 invertor boards and the T con board which did not correct the issue. There are 3 additional boards..the main Power Board,signal board and a tuner board....any idea?
Tampatec ive a phillips 47" lcd tv that bootloops when turned on.
there were a couple of swollen caps on power supply which i replaced but still boot looping, all voltages are present exept for the 12v which seems to be measuring 4.5v?? checked 12v regulator and i think it was ok from what i remember?
now should i replace power board or should i be looking towards main board?
or does this problem sound familiar to you?
Any help would be great.
Thanks
Hey tampatec, I have a LG tv that has pins on the power board labeled with 3.5v, 12v, and 20v, and they all show the appropriate power. I have no picture, but my standby is on when the TV is plugged in. Any ideas? thsnks!
I really need your help... We had a lightning strike hit the apartment and now my TV doesn't work. I replaced the power board and LED driver but the screen never turns on. Have any guesses???
Hey TampaTech I live local in TPA also and have a 55 55l260A13 , it hit and miss with the power on so I believe it's the supply wondering how much it would be to fix if I get my own part ??
Insignia
Hey man, hope you can help me. I have a problem with my Led Tv, the picture suddenly turned purple and it started to shake. There's nothing wrong with the cable. Do you have any idea what might be wrong with it?
Great video thanks for sharing
I have a Vizio P 65", Model:P65-F1, and I am getting a gray screen. I do see backlights, but no picture is displayed, and I did have sound. Any ideas??
tampatec do u know about ic top258pn???in my sony led tv power supply
I have a Samsung UN46EH5000FXZA UD03 , no power, has standby light on and there is a red light on some part on the main board. I have replaced the power board and main board, still does the same. What now?
Hi Tampatec I have a Samsung T240HD, i"m getting a bunch of bright red and purple dots in the center of the screen almost looks rashlike. Have you seen this before and if so what's causing it. Thanks.
Why are there so many different main board models for the same e241-a1 model vizio
I have two TV's of the same model number. I bought the second one for parts only to find out they are two totally different TV's; every part is different. So, I couldn't swap a single thing (the power board) (excluding any frame or the chassis, I presume).
I have an Emerson LCD flat screen. I have sound but no picture. My backlights come on for 10 sec then go off. I did the flashlight test on the screen and I can see AV1 on the screen. What boards would I need to replace to fix this?
I'm having an odd issue with my Vizio M49-C1. Within an hour after turning it on, it will reset itself... turning off and then back on. Usually after that it will be fine for hours without resetting again, though I think it has done it a couple times in a night before. I've also had issues where it wouldn't switch between inputs. The input selector would come up on the screen, but when I selected a different input (Xbox One) it kept going back to the original input (PS4). Once I turned off the PS4 I was finally able to switch to the Xbox. Finally, one night I came home, turned it on using the button on the set, and then neither the remote nor the buttons on the TV itself would respond. I had to unplug it to reset it. Considering the symptoms I'm thinking it may be the main board, but it's really difficult to diagnose when the issues are intermittent. Anyone have these issues before?
Hey tampatec, i have an lg60ln5400, its ok except for a 3” strip of lowered color as the reat of screen, i changed t- con- no change- i have pics, if intrrested
My tv doesn't even light up for standby! It had a loud hum prior and the main HDMI port out! I suspect it was hit by lightening! What would I need to get from shop Jimmy or eBay? Model vizio VW42LFHDTV1OA.. Appreciate any Help!!
Hi tampatec, I'm Paul and have a vizio tv model M551d-A2R, the imagen has frozen every 10 mimutes, I need unpluge the power cord and connect again for onather 10 more minues, any idea of what could be? Thanks.
Really simple and easy to follow :)
hello tempatec do you ever get back to people who ask you question ?
sorry wrong person
Have Sharp Aquos LC 60LE831U will not power up. No stand by voltage. Have not been able to find a psb. Checked Shop Jimmy, Amazon, even Sharp. Found bad diode and will replace this in the mean time but in case this doesn't work, can you suggest anyone else I could find a Delta DPS-183BP A. Rev S4?Thanks
Hi. The power went out completely on my Vizio VX32L when I connected it to the computer. I had both the tv and the computer powered off when I made the connection. When I turned back on, tv was dead, no power. I ordered a new power supply board and replaced it. It still doesn't work. Before I do anything with the mainboard, I am wondering if that could even be the problem. I will try the tests with a multi-meter, but I wonder if the computer aspect has any significance.
I have a question, what happens if you put the Ilive speakers to a vizio tv (D24 D1) and it wouldn't let the tv back on? if so, please reply. thanks .
Hello Tampatec! Huge fan of your work and videos, they have been a great help with a great many television repairs. My question is regarding a Vizio 47" LED tv. The backlight voltage starts at 128v and drops to 66v, regardless whether or not the backlights are plugged in. I get the same voltage and drop with them plugged in or not plugged in. Does this mean there is a power supply issue or a bad led strip(s)?
Eddie Mays can be bad LED strip but use the service manual to find out the running voltage for the LED backlight. I find that if the backlight settings were set to max or too High usually it's the LED strips.
Thank you very much for your reply! Well, if I had the service manual, I would def. take that advise, sadly I do not have it. I only have access to the User Guide. It's a Vizio LED E470i-A0.
Eddie Mays It's not worth the repair. We bought one hardly used for $75. Prices are dropping rapidly!

Hey there, Umm I asked a Q too but this video is 2 years old or more, and it doesnt seem like anyone is answering these anymore sadly.
You can poke around shop jimmys and other parts companies that offer some diagnoses, they might be able to help, I ended up taking my tv to a tech for a free estimate, if you have a local guy who will look at it for free it might be worth that too, good luck.

I have Un55js9000fxza, since I got tv, there was no picture. At one time, it displayed the menu app, and all display was shaking then later it all disappeared. Since then, I've been getting bluish screen, no samsung logo and no picture. Occasionally, I'll hear the led driver board buzzing on low tone- dont know if it's normal. Also when I connect the one box to the main board, the screen will look like there was change scene and went back back to blue screen. I recently replaced the T con and there is no changes. Please help
I have a vizio e60-e3 that will flash the vizio logo on the screen for a split second when the the power button is pushed. Then that's it nothing else. Any idea of what it could be or what to look for?

Hello I need help with my M65-D0
I had a lightning storm issue and my TV when out. No display or status light in the lower left. I google and UA-cam videos on checking out and I thought I had a bad power supply board. I got the board and installed and the old board and the new board did the same thing with the clicking of the relay in the board. Then I continued to check again and I was able to find the the 5 volt signal from the main board was not coming in to the power supply. Then I ordered the main board today I get the board and installed. I powered on and I hear the click and the status light in the lower left turns on but it shuts off again and tried to start again. I have connected the HDMI in to multiple outlets and nothing. I have looked at you videos and the last 2 board are the t con and the LED driver board. But I really would like help in narrowing it down. I don't see any led from the back... or no sound that I can get. Please help.
Hi, I have uniform horizontal lines across the entire screen, coupled with some vertical red lines on on about 2/3 of the screen. The vertical lines are brightness on the left side and gets progressively lighter as you go towards the right side of the screen. My tv is a Samsung Model # un55c7100wfxza, version sq01, type# un55c7100.
Any help will be appreciated.
Thanks.
David
have you ever seen where an x-box 360 can cause the back lights to go out? like a short? first tv was my seiki, 2nd one a samsung. my seiki still does not work even without the xbox system hooked up. thanks
Steve Garrett if there is voltage feedback from a bad Xbox video port or bad hdmi cable it's more likely main board would go out first because hdmi cable is directly connected to that board. unless you have a bad AC outlet causing your tv to go bad. also maxing out backlight brightness to 100% will cause it to go out too. hope that helps
