- LG 47LW6500-UA led lcd tv how to replace/swap mainboard, tv power light comes/turns on but no picture/video no sound/audio only power light is on, no image, blank black screen. In this video I show how to replace an led lcd tv mainboard on an LG led lcd tv that has a power light that turns on but has no picture or sound due to the bad tv mainboard which was caused by a lightning strike during a thunderstorm. This LG led lcd tv was left on during a thunderstorm and we had a lightning strike hit our cable service boxes.

So this ended up solving my problem for only 50 bucks. What's funny is I took the TV to a TV repair shop and the guy saw that the screen was flickering and said that there's no way that this is going to fix my problem and said that the LED lights will need to be replaced. He refused to do the job for $225. I took the TV back home and watched your video and I can't believe this worked for only $50. The guy at the shop missed out on a job that would have paid a lot more.
Yeah and I still had me this tv and still use it everyday. I never had any other issues with this tv after when I made the video and swapped boards
I just replaced my Samsung Mainboard after watching ur video Thank you very much it worked and i got it from Amazon
Thank You! Be sure to ring the bell, that turns on notifications so your alerted when I upload a new video! Hit that like button and share my videos! Thanks!!
Nice video well done. I repair tvs for a living. Just letting you know that the issue has nothing to do with lightning strikes etc. These LG models have a common fault that makes them do this. It's almost every model around the 2011 release that are susceptible. You may find with time the same thing could happen to this new board.
You can normally fix the issue on the main board by removing it. Taking off the large black heat since that sits over the main chip and reflowing it with a heat gun or 8 minutes in the oven at a particular temperature. Just google 'main board relow'. Basically over time the solder joints crack and become disconnected. Hope this helps!
Thanks so much for sharing this! I did see some videos that these boards have that issue and you have to do that with the heat gun. It was weird because as soon as we heard the thunder hit right after the lighting outside like right outside the dang window it was super loud the tv went out and stopped working so did the cable service. I think for this one that’s what happened but I know what your saying is a common issue and the viewers to this video will appreciate your feedback on this because they Might be having that exact issue. So thanks so much for leaving such a helpful comment!!! Have a good one!!
@@jamiewagner Haha no worries it definitely does sound like it was a lightning strike for sure. And no problem at all. Love to help peeps save money and not throw things out when I can :) I have about 10+ of these TV's I need to fix because of this issue... One day lol
yea good luck getting to them! your probably busy enough doing it for a living! I'm always glad when people like you leave good helpful comments worth reading and sharing!! Have a good one dude!

Excellent video. Didn't waste any time. Thanks.

I wonder if another main board from a TV of the same size and model would work on mine. I have a 55LV5400 and cannot find the matching board part number (EBTxx) or board number (EAXxxx).
You should keep looking to get the exact board, they are hard to find,
Excellent video Jamie! I am having almost the exact same issues with my Panasonic TC-39AS530U. TV turns on, screen flickers 3 times (I can see the LED lights flickering in the back), then I get a blank screen with 1 LED flicker (error code 1 I assume) then just a slowly blinking red LED. There is no sound and I can't turn it off with the remote. I have to press and hold the power button on the side of the unit or unplug it to turn it off. I have tested my power supply board. ALL 3 test points (standby, LED driver, and main board) maintain voltage when it goes from power on to blinking light. However, the pins on the connector for the main board and driver board go from 16V and 24V respectively down to 0 when the light starts to blink.
There are 3 test points on the main board, 5.3V, 12V, and 15V. The 5.3V (standby) maintains voltage when it goes from power on to blinking light, the other two do not, they go to 0. Would that, along with voltages being maintained on the power supply board, indicate that this main board is bad? I really hope that is the case as I do not want to get into replacing LED strips. Thanks and keep up the great work! P.S. I have put in new power supply and T-con boards and the problem continues.
good luck with it, I still use this TV to this day and it still working good!
Thank you for clearing my doubts, I was confused as for the problem was on the Main Board or on the Power Supply Board. But it would have been better if you've shown us how to test the Main Board for faulty components! Next video... maybe?
yea maybe next video! that's a good idea how to test that board. I still have the bad board from the video so I could still test it because of course its bad. I saved it so I still have the bad board.
@@jamiewagner Great! I'll be waiting!
Yea cause I'm trying to fix mine to. And I'm stuck on fixing it. Lightning struck this one too. But I don't know how to determine what it is I need to replace
OK
Great video! Thanks! I'll be fixing mine tomorrow! ✌

i need help i have insignia tv was hit by lighting the red power botton is on but nothing shows could it be the same issue as yours??
yes possibly but I don't know for sure.
Hello, I have an LG 42LE8500 TV and it has the same problem as yours, please, where can I get the main board, I'm in Colombia, help me, I'll pay for it and pay the shipping.
You're going to have to search for it on Google on the Internet and try and locate the board. I had to try to do that it took me a while to find one. It's an old TV now so it might be harder to try and find the board. I'm sure there's not many left.
I have an LG tv with the no picture no sound issue. How come if I turn it off and back on the tv will work for a bit? When there is no picture,the tv is still backlit. It almost acts like something that overheats but the tv is cool to the touch everywhere. When I get the picture and sound on it will work for either 1 minute or sometimes up to 10 minutes. What do I do?👀
Actually yes that’s a common problem with some of them sometimes it’s that heat sink thing and you have to like do something to it to get this issue fixed you’re not the only one having that issue I’ve seen other videos where people are having similar issues I’m not certain of how they fixed it so you might have to search around on UA-cam
Hey mate I'm from Australia. I got a 55lw6500. I need a motherboard do u know to buy one from
I'm not sure you have to go on Google and google it. This motherboard is not easy to find and it's probably discontinued so it's going to be difficult to find.
I have an OSKAR 16" LED TV in which off -0n light saw the tv is on but there is no sound & picture screen is black, kindly suggest what to do
Not sure your gonna have to troubleshoot it some more it’s a different model than mine
Did you have backlights?
I don’t think so
That's DOOOPPPE! Thanks man!
thanks B please hit the like button on a few of my new UA-cam videos it helps me to keep creating helpful content like this for everyone
My LG model 55LE5400 is doing almost the same thing, but I am getting audio. Audio, and bezel lights up. There is no video output at all , no display at all on LCD. Tried resetting power, no effect. Tried all inputs and volume increases with remote. No Logo displayed on boot up. Please advise as to what I can do to have this unit repaired at little to no cost. Tried heating in toaster over at 380F for 10 minutes to no avail. No visible issues on the main board. No bulging caps, etc...
TV is cosmetically pristine and used very lightly, was very surprised that this happened. Any Suggestions?
Not 100% sure but it might be your main board as well, have you tried all the different HDMI ports? be sure to try them all first and see if that makes a difference. My issue was due to a thunderstorm/lightning strike. So I am not sure if yours would be the same issue. It could be your main board like mine in this video but I can't advise for sure.
George pelosi mine has the same issue,did you find a solution and if yes what was the issue? Thank you
Your too cute, I love how you made this seem so easy, no problem. And made it sound like lightening striking the box was a normal occurrence! Your hilarious! You must be an electrician or something. Lol, this never worked for us when we tried to fix our tv in the past. Had a guy come to the house still nothing worked. I bet you must get millions of questions from people trying to fix their tv problems. We have an old but good tv, 2006 Panasonic High Definition Plasma TH-42PX600U, the volume stopped working on the Dish Network remote but the buttons and volume on the tv itself stopped working also. Is this something fixable do you think?
Lol well thanks! It sounds like it could possibly be fixable both the tv and remote I mean I’m not a professional but I guess you would have to check with someone who does tv repair and see if it’s worth it to possibly attempt to fix it. You might end up having to pay something to get it fixed. Not sure..
Jamie Wagner thank you, your right, I think I may start with calling Panasonic to see what they can tell me and yes I’d have to check with a tv repair person to see if it’s worth fixing, I’m not so sure with TVs this old if it’s worth it, my dad paid over 2k for it in 2006 but it literally is on almost 24/7 so more then the volume could possibly stop working soon, plasmas usually only last about 10 yrs from what I hear, not sure if that’s true but, thank you for the info I appreciate it.
Hi I got one LG tv no sound no image but I got a white bar on the left side of the screen could be the main board? Thank you. The model is 49uf850v
I'm not real sure about that one. I might be something else causing that issue. Sorry not real sure..
Hey man! Im fixing my 50inch smart tv, it has sound and backlights but no video. Thought it was a tcon board problem so i replaced it with a new part, but the problem still persists. Im thinking its the main board... do you know some common mainboard problems you can enlighten me on?
This is the only issue I ever had with it, I replaced the main board and then it worked fine. I was very happy and it still works perfect
Hi great video,where did you get the replacement board and how much was it please thanks
Hey thanks! I had to search for it on google and it was like $80
I have the same issue my red light is on but my tv will not turn on at all ...i experienced the same problem when there was a big storm and lighting hit and burned out my cable box and tv just dimmed out ...I just bought the main board I hope this is the problem because it’s much cheaper to fix the tv then buy a whole other one ...btw I have a 60in led 4K LG tv
yeah that's a nice tv just like mine except mine is 47" but yeah good luck with it I hope it works for you as well, Mine still works just fine since I did this video. no new lighting strikes yet, lol, but this replacement board allowed me to get many more hours and use out of this TV. I still have it and it's still working well.
Bro I have lg 49 inch led Tv. Red light blink 3 time no power on no sound. What I do plz help
That’s a code for something check you owners manual
Hello how are you? Could you please help me and tell me where you bought and you got that spare? I have the Lg tv 47LW6500 exactly the same as yours and I do not get that part in google or any other page! Can you tell me where or which page did you buy it? very thankful.
I think it was called tvpartstoday.com
@@jamiewagner Thankyou very much! But i think is out of Stock -.-. It´s so sad.
yea that sucks if it's out of stock, I believe this model is getting very old, not many parts left to order
I have an Element smart Fire TV. It turns on and after a few minutes the video goes but I have backlight and sound, if I turn the TV off and on then it works again for a few minutes.. any idea? TCon board?
yeah that's a crazy one , yeah it might be the TCon board I'm not sure on that one.
I have a an apex tv and I have the same problem, i haven’t used it in so long and it just won’t turn on
If it’s not turning on that might actually be a power supply issue it might not be the main board you might want to make sure you test it as much as possible it may be a different issue
where you buy the board at?
Online but I forget where
My tv is the LG 55UF6450 and has the exact same problem and I thought it was the power supply I ordered a new one and that didn’t fix it so I guess I can try to cook the mainboard to reflow the board to get it working since I got nothing to lose. But also cause it’s hard to get main boards for my tv.
yeah it was really hard for me to find one for this tv
@@jamiewagner I tried it yesterday sadly it didn’t fix my problem so I might need to get a new tv sadly.
well probably better to get a new one anyway, prices have come way down on most tv's anymore, believe it or not I still have this tv and it still works fine with this replacement board. So it's still going!!
@@jamiewagner yeah I’m going to switch to Samsung and I still have one of my Samsung tv still going strong after 12 years of use and had no problems so a Samsung tv will last a good time.
Have a good day!
My rca tv wont come on but the red light is on and the power button is broken but it has to be some type of way to get it on without getting a new one 😭 please help me
Your gonna have to trouble shoot it. If the red light is on then that means it’s getting power but your issue sounds like a problem with the power supply board or the a screen issue which may be different then a main board issue like mine in this video.
I would take off "Fix/Repair" of your video title and instead label as "LG LED LCD Main Board Replacement" or "Swap". I assumed a fix/repair would go over the steps to test and determine what board or part is defective. A swap of boards is easy, yes, however there are still those of us that would like to know why and or what part of the board is faulty. Your title is technically false and misleading.
Thank you Cristen I think you right and I apologize for it to seem misleading, not my intention at all, I’m probably going to change the title to what your suggesting it sounds good and a lot more related to the video. I was just hoping it helped others out with similar issue. I wish I could have test the board and showed more steps like that but I don’t have the correct gadgets to do that. I fixed the Title and the description to better fit the video! Thanks!!👍
Hey bro, I have LG 42lw5700 tv It hasn't Screen mirroring. How can I do it
I think you do that from your phone
Nice video sir
Can you tell me the name of main board ??.... what is price of board
I have same problem
Plz reply
Just type in the model number into google and you can find it.
I have a element model elefw328 and when I plug it in it has the red led turn on but it won’t power up idk what to do
Check to see if your board has a reset switch or something
I am having same problem as you. However, i replaced the main board and the problem didnt get fixed. Any ideas? What would you have done next if yours didnt correct after replacing the main board? Thanks!
It’s probably not the power board but there’s another one on there for the screen I forget what it’s called i would consider that one next if it’s cheap. Mine is still working just fine since I did the video. Sorry it didn’t help. It fixed mine. But that’s where I would check next. It might be called t-con board but I’m not sure. It’s the one that controls the screen not the mainboard or power board there’s another one it could be
I need help when i put the cord on my tv the power board does a wired sound coming from the wired battery things .
Might be the capacitors or power supply making noise
so my power supply should be good than? its like should be the source input board issue or both could've be damaged? i almost ordered a new psu for my tv 0_o i have the exact issue...?!?!?
it's hard to tell what your exact issue is but I know my TV works fine now and even since I did the video still working perfectly fine.
ok thanks
I have a problem where the sound works, but no picture. I’m guessing a soldering problem on the main board, but I don’t know where the picture connection is. Any help?
Not sure about that one
Did u fix it
Yes I did and it still works fine today
Nice... How did you determine it was not the power supply board ?
I really had know way of testing it, I just figured since it had power and was having no power issues that it wasn't the power supply, so I moved on to the main board. I guess I got lucky because I never tested it, probably not the best option to do but I just kept my fingers crossed that I was right considering my issue, so I went a head and replaced it and since this video the TV has worked perfectly since. Still using it every day. Had the issue been it didn't power on at all then I would have assumed the power supply first.
I have the same issue with the same LG Tv which you have repaired in the video & I would like to replace the main board but would you please tell me the price of this main board and where can I buy that?
I think it’s around $88 you need to type the model number into google and search for it it’s tricky to find but you have find the exact model mainboard try to google it first and then try eBay
Thanks for your reply, Is it possible to repair the same main board?
@@jamiewagner please, can u sed me the web page .... where do you but it?
I have have the same issue my 86” Lg got hit by lightning as well, I got a price quote on how much it would cost to get it fixed and they quoted me $650!!! I mean what the heck!!! People really do like to take advantage sometimes 😒😒😒
that's alot, I'm still using this TV to this date and it works fine, the board replacement did the trick for mine and it has held up just fine.
Where did you order the replacement board from??
I googled the board part number on Google and I found it that way good luck finding one of these boards it was difficult to find it
ebay or Amazon
Hey sir, could u answer me this please. Do u think it is posible that my usb hard drive damage my tv? I watched movie of my usb hard drive and suddenly my tv freezed, black screen and on repair they said that tv cpu or motherboard burned, is it posible that usb hard drive that does not have adapet and is powered by tv could do this?
I guess anything is possibly maybe the TVs power supply was over working trying to keep that usb drive powered on all the time but you would think that it could handle that as it shouldn’t require that much draw
Thanks. I got new tv, but same model. I tested it last 2 days with same external hdd and all is good. Guess that first one was factory broken as i had him for 1 day before it freezed and died.
the tv is LG 55SK8000 PLA/PUA
Same problem, similar TV model LG 55LW5600...replaced all 3 boards and still no picture, no audio T.T... I should've just left to the professionals
yea that's a lot of time and money you must have went through, sorry to hear that, it's gotta be something causing the issue, I hope you can get it all figured out, and I don't think you can return electronics stuff either
did you replace the ribbon cables too? its very unusual to have no audio if you have replaced power board and main board. with the tv on, and the room lights off, shine a flashlight onto the screen and check if there in an image, if so then your LEDs are shorted, nonetheless you should still get audio tho.
Hi, where did you buy the board.
I put it in the description like I forget where it was but I have it on email if you really need to know I would just have to double check it’s like TV parts some thing online it was really hard to find it
Could you check it out for me.
Please?
@@carltonmoncrieffe1516 I am in need of a board for an lg42le5400. Same exact issue as described in the video. Please let us know where to purchase these boards.
It will be really helpful mate if you can tell me where did you buy the new board please hoping for a reply.
I had to search google for it by it’s model number. I mentioned it in one of the comments but I would have to look for it
Jamie Wagner been there done that but all I find is just out of stock option .
I had that happen to I just kept looking around for one. I remember I ordered from TV Parts Today, just google that and see if you can find one on there website.
kindly guide me i wabt thi board
You have to Google the model number or part number on Google to try and find this board it’s probably not available anymore because it’s very old
Hi. Where can i buy the mainboard. Do you have any recommandation. Thanks.
You have to look on google for one from somewhere or go through your tv manufacture
Don’t you think the price and supplier would have been important to mention? I want one but don’t know how much or where you got it?
I do apologize about that this was kind of an isolated project not really meant to fix everybody’s issues but I had to research it on Google searching for the model of my TV and the part number of the motherboard in order to narrow it down to the correct one the problem with me sharing all that as it maybe different for so many peopleAnd I just didn’t want to confuse anyone
Where did you purchase the new board?
47 sec into the video where i'm pointing to the label on the back you can try and pause the video so you can see to the left of my finger where it says SVC CODE, this is the service code. I typed it into Google and search around online until I found and exact mainboard match. That's how you should do it, if you have a newer TV then it will be easier for you to find a new board but mine is older and I had to really dig to find one and when I did finally find it it was $88.00. My TV is completely fixed now.
Jamie Wagner thanks! I found the number on mine as well. I put my board in the oven and it fixed it.
Wow in the oven? That’s amazing! I’m glad it fixed it!!
385F for 10 mins? I'm about to give mine a shot.
@@burb17 what do you mean you put it in the oven and was oven on or warm? Please could you explain. Thanks
I got the same tv stop working about 4 years ago I just took it off the wall and got a new one I think I will fix it now thanks for the video, but I will never buy lg again.
Mine is still working after this fix but I might get a Samsung
Thanks for you trying to help, but I could not take the camera being too active. My God! Try to keep the camera as still as possible next time.
Thanks for the feedback I will try next time.
Lg lcd problem display aata jata he
👍
at the beginning of the video I thought I was watching a Michael Bay movie. the camera movement was too much, slow down buddy.
yeah others said that to, I will slow down in the future
You did not actually trouble shoot and repair the TV super easy not really helping
yea but if having issues similar to mine at least I showed that replacing the mainboard did in fact repair it 100%. this might not be the perfect fix for everyone, it saved me a lot of money from just running out and buying a new TV.
There is a video on UA-cam about this problem trust me you don't need to buy a new board what this guy did he cut a piece of cardboard and place the board on it and cover the whole thing with aluminum and put it on the oven for 10 minute and guess what it works I didn't have to buy the a new main board look it up it really works I couldn't believe it my self
I know it does, I did see the video, and it does work in some situations
Your camera work made me dizzy!
sorry!
Dude..stop moving the camera so much.!!!
My bad
دخخخخخخخخخخخ
👍
Jamie, Your video skills are terrible. it would have been great if you slowed down instead of just waving the camera over the board and maybe showed how to remove each connector from the main board.
Yeah I was a little bit all over the place in this video with The camera
