I had this problem with my Samsung 42" LED. I found 2- capacitors on the power board were swelling up at the top. I ordered a bag of 6 capacitors with a slightly higher voltage rating. I removed the swollen ones and soldered in the new ones. It worked! That was 4- years ago, and I still get a good feeling when I think about how I saved my TV from ending up in the trash dump. UA-cam is the best thing for do it yourselfers.
THANK YOU. This video just saved me several hundred dollars and saved the local landfill from yet another old TV set. Your illustration of what bad capacitors look like was especially helpful-it allowed me to correctly identify the two blown capacitors on the power supply circuit board of my 2009 Samsung LN46B750. After literally four dollars at the local electronics supply store and a bit of careful soldering, it works again! Thanks!
I think your videos are awesome and have saved me so much money. You make the repairs easy for the most electronic illiterate people. Thanks and happy holidays!!!
Very well done, and many aspects of the problems explained while describing the various components and how they work and what they do. Bravo and thanks!
Hello, and great videos. I have a Sanyo DP50842 which will not power on or have a standby light. The power supply is brand new. Do you think it is the analog board? I will keep the new power supply. Any tips will help.
I have a samsung UN39EH5003FXZA that shows a standby light when the TV is plugged in, but no functions or lights work. The TV worked fine until I installed a firmware upgrade, when the upgrade was finished the tv turned off and will not turn on. What do you recommend for trouble-shooting? many thanks Ralph
I have this exact make and model and originally figured the power board was my issue as l had not a power/standby lite, no leds lighting, no sound/picture, I ordered the power board and just received it today.(great service by the way real fast delivery) Now with the new powerboard in l am seeing the power/standby lite and when it is powered on l get a chime, the LEDs illuminate momentarily and l can see the indicators on the screen but then it shuts off and repeats this every 5 or so seconds. I can see all the led back lites are working but only momentarily. I have just ordered the main board as l am assuming this is the problem now any direction would be appreciated.
Thanks for the great videos!!! I have a TCL 50” smart tv. 50S434 model. I have horizontal thin black lines on the lower half of my screen. Everything else works fine.. I only see 1 control panel in the center of the rear of tv.. could this be my problem???
Thanks for the video information, really appreciate it. Although it was very informative, I took my LED TV apart (UN50F5500AFXZA) and could not find no capacitor, electrical connection, or anything abnormal from either the main board or power supply board. The next task I will be doing is plugging power and reading voltage out of several components to see if I have power going out to such. Besides this, anything else you recommend? I am definitely not buying another samsung and or paying for their repair center to fix it. Anything else you can recommend, please do so. Much appreciated; Sal
By the way, the problem with my TV is, I get no screen, the Standby LED does not remain on, when I press remote control, LED blinkers as if receiving signal from the remote control. When I disconnect everything, and only hook the power, the power LED stays on, I turn TV on, it works. But after connecting the rest of the cables and watch TV for a little, after turn it off, it goes back to no-work status and the same thing happens (power LED is off but blinkers when remote control is pressed, TV does not turn on). Hope it makes sense...
Most likely and almost always it's the capacitors in the power supply that go bad. Capacitors tho sometimes they do swell up don't always. I just replaced about 9 capacitors in an amplifier and none were swollen. This is due to Chinese POS capacitors. If you look on the net theres a whole write up about caps and how the Chinese ones are made. They don't use the proper electrolytes internally and in turn they degrade much faster than high quality caps. One thing to note about capacitors is that on the side along with the voltage which can go higher but not lower than stock. Is also the uf or microfarads and also the temperature. The operating temperature that is optimal is 105° temperature. This is due to the fact that that is the operating temperature point where the insides liquify. Or begin to swish around. Being that 105 is the highest they can operate they only come in 105° and 85°. Therefore a 105 cap can run hotter than an 85. This means that it will take much more heat to get the cap to liquify and begin to lose it's value in uf. This also is important because shitty Chinese caps don't have adequate sealing rubber and this causes them to leak and then they permanently lose their value in uf. Causing the issues you guys are having with your tvs. These types of issues don't just plague tvs, they plague anything with a capacitor inside. The reason tvs have this issue is because people leave them on for hours and hours and guess what happens? The caps get hot turn to liquid and lose their value. There's no tv that this won't happen with and personally I've had Samsung tvs that outlasted all others. If you truly don't want this problem with your tv. As soon as you buy it open it up and see what kinda caps are inside. If they are cheap shitty Chinese caps and you can look on the net to see what brands are shit and what ones are good. Replace them as soon as you buy the damn thing. There are other inherent problems with capacitors also that are made wrong. Like the electrolyte has too much water in it which in turn cause corrosion and other issues like leakage sooner than normal. If you replace these caps before this happens even with a much higher voltage you will never and I mean never have these issues. Especially if you replace them with good american made capacitors. Or even good japanese capacitors. There are lots of good caps out there not all american ones are top shelf either. But replacing shit crap caps with high quality caps will save the life of your tv. Caps filter the signal either ac filter frequency or dc filter voltage I believe I can't remember at the moment. And when this no longer happens it can cause other components to begin to fail. Usually semiconductors. And there is no need to replace the entire board. Caps are cheap guys if they have a stripe on one side they are bipolar meaning they have a + and a -. The negative is the stripe side of the cap and on your circuit board is a mark of some sort. To show which side is negative. EVERYTHING EVER MADE HAS SOME SORT OF MARK ON IT DESIGNATING THE NEGATIVE SIDE OF A BIPOLAR CAPACITOR. if there is no mark to designate the negative then there most likely isn't a stripe on the cap. In this case the cap is just an electrolytic capacitor. And there are other types of caps that will work in it's place also. Some are better than the ones they use for tvs. Like polypropylene or mylar. And there's also ways to read these even tho they put the uf in different terms like some will say J on them. Or other letters. But on the net there is a primer or some sort of key as to how to read them. Guys this isn't rocket science, these letters are just like bytes, kilobytes, megabytes, gigabytes etc. Each letter designates either an up or down in values. Usually in decimals. And if you don't know how to read that they have converters that will show you how to do this or what other caps can be used or which ones are good, better or best. A good place to start looking for this type of cap or also a key to look the values up and also calling customer service is PARTS EXPRESS! They have a 1-800 number I believe is 1-800-express. And 24 hour a day customer service that will assist you in making this choice for parts. This shit is so fuckin cheap it's not even funny guys. You can literally replace every cap in your entire tv for prolly 30 bucks. And a new board will run you about 70 to 100 bucks in most cases. Depending on the brand, age and how rare it is. Take the time to buy new caps and try it. The ones I replaced in this amp looked completely normal. But once I got them out you could shake one of them and feel the wrapping junk inside shaking around. That means all the electrolyte is gone. That cap is trash but it's not swelled. I read that this is because the shitty seals they used inside leak when it turned to liquid on the inside. So it's not necessarily that it turns to liquid that makes it bad. It's that it leaks while it's liquid. Now some have to be replaced with the same temperature and I can't remember which ones do and which ones don't off the top of my head. But you know who will know? Parts express customer service. They have knowledgeable sales and service staff that can help you all day long. Take my advice replace the caps and try it even if they don't look bad. The guy saying there are none doesnt know how to identify caps. They come in different packages and different shapes and sizes. And once you've done this once or twice its easy as hell. And your tv will work for years to come. If you replace them when they are new and or put a small fan on the back of the tv to keep it cool so that it doesn't run hot to begin with that tv should last forever. In the electronics world caps are the only item that degrades simply with time. Resistors don't semiconductors don't inductors don't nothing else does besides caps. So if you put some good ones in them when they are still fresh and everything works. Or at least check them to see if they are crapola caps and replace them with good ones. The tv will work forever. Now leds going bad is another story altogether. Leds are just a diode that's also a light. They come on strips on the inside of the tv and can be purchased off eBay in sets for your individual tv. You can make them light up with a 9 volt battery by soldering wires to the tips of the battery and then using the battery to touch the contact points of the leds themselves or the end connection at the start of the strip. Altho the whole strip may not be able to light up with only 9 volts. Best way to do it is by looking which is + on the strip and which is negative on the strip and realizing that positive in on the strip goes to the positive of the first led. Then coming from that same led is the negative on the opposite side Simple. Take the battery and take positive and touch it to positive on the led and the negative to the other side of the led and boom it should light up. Once you Figure out which lights are bad, you can then replace them individually. And you can replace them with anything. Get an led light bulb even if the color is different and they don't look the same they will work. If it's superbowl Sunday and the big tv in the living room is out in a pinch you can replace these with anything that has an led in it. And they are wired in a series. Which means like old Christmas lights when one goes bad they all stop working so you can literally just make a jumper to jump or connect the positive and negative that we're hooked to an led together and it will start working again. Superbowl is back on in 10 minutes. Folks I taught myself this shit by sitting down and thinking about it a little bit. The more you learn about electronics the more you'll realize there's nothing to fear when you have a broken tv set or any electronic device. You can't break it it's already broke. So anything you try is called LEARNING. Sit down and fuckin tear shit open. Im no genius, im just a guy who isn't Afraid to tear the tv, washing machine, telephone, amplifier etc apart to see what the fuck is wrong with it. And eventually you learn that it's not as hard as you thought. House hold electronics steps voltage down because 110 isn't needed in most modern devices. Car electronics step voltage up because when house hold voltage steps down it doesn't usually step down to 12 volts. And see household voltage is fairly steady. Where as a car depends upon the alternator to produce current and if the motors not spinning at 3k rpms then guess what? There not enough voltage. But your house doesn't have that motor to spin that alternator. So it can produce that voltage even steadier when it's stepped down. Every half down in voltage creates a double up in amperage. LEARN!!!!! Rock on people\m/
I have a Samsung UN40EH5000FXZA version TS02. Standby light is on but intermittently will not turn on. Sometimes works fine for days or weeks, then acts up. Thoughts?
Today my SAMSUNG would not turn on, even though the standby light was working and it made the turn on chime sound when I was trying to turn it on. It was all due to a defective 1,200uF 25vdc electrolytic capacitor. You could immediately see that the top of the capacitor was bulging. I replaced the capacitor and it was as good as new. Years ago I had random turn on problems with the same TV, but at that time it was due to oxidized connector contacts. All I had to do was unplug and re-plug all of the internal connectors several times, That had fixed the problem by having scraped off the oxidization. Anyhow, this TV has been working now for 11 years and it works just as good as when it was new.
I have a UN55J6201AF with the same board layout. I tested voltages across the connecting cable and got similar numbers but when I disconnected it, the LED’s did NOT come on. Does this mean the power board is bad, or the LED’s ? What do you recommend?
Do you have any videos on troubleshooting a Aquos Sharp television? My television is not working and I tested the fuses which is functioning. I am not certain what could be causing the tv to suddenly stop working.
I just replaced a bad power supply board in a 55 in Samsung led tv with no power and no status light. It lasted apx 20 minutes before going out again. What could be shorted causing power supply failure. Thanks for your videos and any help you might give on my problem...
Hi....we have a Samsung UN55H6350 tv that has a dark screen and no sound. The Standby light and the backlight of the tv come on, when the tv is powered on.Also, the Smart tv logo comes on for a second then the screen goes dark. Further, the tv won’t power off using the remote. Could you please suggest whether replacing the main board might work?
I have a Vizio D55u-d1 that has standby voltage and front light but wont power on at all and the 12v outs on the power supply read 19v and the 24v read 22v. any thoughts? should I just replace the power supply? I still get 19v even with all other boards unplugged.
I have Blaupunkt 43/134M-GB-11B-FEGUK-UK That won't switch on. I can see on motherboard RB148 blown on CB120. can you direct me what resistor I need to replace please
Hello i have Thomson 40FZ5533 model TV with burned main board, the board that i buy is the same 40-MT51SS-MAC2HG but it's from tv that is 48FZ5635 model , the serial number of the boards is the same but the board its slightly diferent from mine, can my tv works with the other board ?
I have a Samsung UN40H5500. The standby light is on and not flashing. However, when I press the power button, the backlights flash once really brightly and then nothing happens. No screen and no audio. There is no visible damage to the either the main board or power supply board.
+Brett Ramsey Try all repairs and troubleshooting at your own risk. This sounds like you have bad LEDs in your TV. Unfortunately we do not sell replacement LEDs for your TV model number at this time. You can check back in the future to see if we have them available. Thanks! www.shopjimmy.com
ShopJimmy.com I got a Un55h6203afxza samsung tv. I found it had bad leds with the flash light test and also testing them with a led tester. Also checked power coming off board to led. it was really high voltage. I then replaced the power supply and leds. upon completion I plugged the tv in and now I'm. not getting the stand by light. think I have a bad board?
A friend of mine had a power surge, the TV is an INSIGNIA model # NS-50 D40SNA14 there is no stand by light, it's completely dead, I took it apart and noticed an IC Chip # A6069H had a chunk blown out of it, could this .30 cent piece be the cause? the power board # is B166-705 D46 REV B do you carry a replacement for this TV? please advise, thank you from Ont Canada
Hello I have UN55ES7500FXZA and it just shut off but does have a standby light, When I plug it in I hear it clicking inside but does not turn on.... The screen is fine I thinm.. But deny click.?? Does this sound like the Power Supply Board to you.?????? Thanks for help..
I have a Samsung UN55NU6950F When I plug it in the backlights immediately come on. There is no standby light and I can’t see any picture with a flashlight nor hear any sound. This unit has a single board. I disconnected the flat cables individually and both and the backlight remains on. No apparent bad components. I have scanned the board with a magnifying glass. No weird smells either. Is there any additional troubleshooting I can do? Does this sound like the board needs to be replaced?
Your video was very helpful. We have a Samsung LN46B630N1F. I was able to determine that a component on the power supply board burned out. Do you have any replacement boards for this model available, and if so, what would the cost be?
I have a Samsung UN32EH5000F. Replaced the power board and the main board but still cannot power on. What I have found when I unplug the backlight I can power it on but not when is plugged back. The plug for the backlight says D-, +5V, -5V, and D+ I do not have +5V when I check that pin but there is +5V to the main board. Any clue what can be wrong? Thanks
Thanks for the video. I replaced the my BN44-00341A with the 00341B board. It worked on the first try, then I turned the TV off and relocated. It FAILED again. (all this happened within 10 mins).......... Should I trash this TV?

Hello,i have a 23"Samsung tv le23R87BD.After power switch on,it turns after 5 min.it run smooth after that. Can you tell me which board has defect? Thanks
My un55j620dafxza power supply indicates 13v on output pins except 2 for ground. 1/2 of them read 13v the other 1/2 only about 3v. I suspect a bad P/S. Please advise.
I just took my tv backing off and checked capacitors, they all appeared to be in good condition. I found this video and disconnected this exact same cable, but my tv would still not function. I plugged it back in and my tv works fine now. I'm not sure why unplugging this cable and then plugging it back in worked, but it did.
Just replaced power supply board.. TV works now, but have dark shaded bar running horizontally thru the middle of the screen. Could this be a bad power supply board? TV never had backlight issues...
my friend has a tv exactly like this with a long t-con board at the bottom i've been trying to find a replacement but have had no luck do you know a site i can go to, to find a replacement.
I have installed a new power board and a new main board and still no luck... Any ideas? I have standby power and the back light turns on, but no picture. I hear the menu beep when turned on, but then it just cycles trying to turn on over and over again.... Any ideas are greatly appreciated!

Have samsung le37 A557P2FXXU Fault:- When switched on at wall it will show red standby light but will dim out and die when remote is used. Changed power and main board still the problem exists. Works perfect when left in standby mode . Any ideas as im running out of bits to replace? thanks
I have a samsung UN55FH6003F tv. Issue started with the tv not wanting to power on. Solid red stand by light, no blinking that I have seen. If you waited for a while or unplugged the tv for about 10 minutes, it would turn on. That worked for a couple of weeks, but now it won't turn on at all. Using the remote or the button on the tv has no effect. I replaced the power board, and have the same exact issue, no change. Is it likely the main board?
I've used magic power module before and it worked but now there's no power anymore but if I remove the cable connecting to the main board the backlight will start and then if I put it back it won't on. And no standby indicating. Is it that the main board is dead?
My LG LED 3D SMART TV with product number 47LW5700 is not coming on, I was told the main board is the issue, can you please advise if this is true and how much it will cost?

I have a Samsung UN50H6201. The standby light is not on but the TV does this strobe effect like it wants to fire up but it can't. Is this a power supply problem?
Great advice in your videos. My tv s stndyby light but when turning on screen shows logo (JVC) for one second then nothing. To get standby light back I have to unplug and replug but tv still only flashes logo. Could this be the power board.
I have a Samsung LN-S4051DX that won't power on. It just clicks and has no standby light. I've tested all caps and they are good. And when I test the power board, I am getting overvoltage. Where the 13v pin is, I get 18v until it clicks, then it goes down and comes back up to 18, then repeats over and over. The three 6.4v pins are at correct voltage until the click, then they go down and come back up. And last, the 12v pins all have 26v, then drop down and back up. Board looks good. No burnt spots or cold joints. Sounds like a humming noise coming from transistor the whole time it's plugged in and clicking as well. Any ideas?
My samsung tvs power cuts in and out. The screen flashes then goes black, same with the audio. Both can happen up to 10-20 times per minute. I was told it started after a storm. Lightening maybe? Just replace the power board you think?
I have a samsung led smart tv un50h6201af with no picture, its has sound and backlight are on i looked at boards and their is no visible damage to the boards. Checked the ribbons to see if any of them was loose and they was not. I checked the fuse to the t con with my craftman multimeter to check the voltage going to t con board and there was no volts or standby volts. Do i replace the power supply board or is their more ways to troubleshoot the tv to get a better diagnosis. I tryed checking the volts to the power supply board but i didnt get a read
I have a samsung un55nu6900f and it has stand by light on but won 't turn on.I can get it to work if I PRESS AND HOLD the power button on the tv itself.

my 60 samsung smart tv won't power on. I've replaced the power supply board as there was a visible burnt component. but it still would not power on. when I disconnected the main board I got back lights working but nothing else. when I plug the power supply back to the main board the back lights go back off.
Have 2 Samsung UN50ES1650FXZA both with same symptoms. When you plug tv in standby light is solid once power button is pressed light does 2 short blinks, 5 times then stays solid and repeats. Visual inspection of all boards is good. Unplugged main board from PSU LED will come on. Testing plug on PSU to main (5v pins) getting 7 volts but jumps with blink of standby. If I plug tv in and do not press power button standby light will stay solid with screen off, and same plugs shows 0 volts to main.

Hello, I have a Samsung model HL72A650C1FXZA and last night the picture was real dark and now today I tried to turn it on and I hear the music but blank screen and the green lite flashes for a few seconds then a red and green lite flash once then back to just green lite flashing and I can't turn it off or anything. I looked for damaged capacitors but did not see any on the power supply card. Oh, and I already had the LCD replaced because of all the white dots. Any ideas????? Thanks
Hello, After purchasing a new Samsung remote, installing new batteries, and draining the power from both the TV and the remote, the remote still will not power on/off the TV. I tried to use the jog switch to reset the TV, but I need a remote to enter the PIN. Then to make everything worse, I accidentally locked the panel key- now the jog switch is useless. Is there a way to unlock the panel key without a working remote? model # UN50H5203AF- MH01
My Samsung Smart T.V. LED Model Number UN55J6201AF was purchased 2 1/2 months ago and it just shut down, there is no power and the standby light isn't lit either.....ANY ADVICE or DO YOU KNOW WHAT COULD BE WRONG...
My Samsung LN40D630M3FXZA stop displaying an image, I can turn the TV on and off and the stand by light stays on and will blink if I press any buttons on the remote, while the TV is on the screen will flash very dimly. This started after having a non-powered external USB drive connected for an hour that had water damaged and wasn’t fully dried. The TV was working connected to the USB for an hour before it began acting this way. There doesn’t seem to be any damage components on the Mainboard and power supply boardDo you think only the Power supply board would be effected?

Thank you so much sir I've changed one puffy capacitor which has value 47 mfd 200 v.
After changing the capacitor tv works normally..
Just replaced my Samsung UN50EH6000FXZA main board with the this main board BN96-25798A for shop jimmy and my TV works again. Thanks.
Very well done, and many aspects of the problems explained while describing the various components and how they work and what they do. Bravo and thanks!
Thank you my tv problem is the main board and I ready purchased in your page thank you 🙏
Hello, and great videos. I have a Sanyo DP50842 which will not power on or have a standby light. The power supply is brand new. Do you think it is the analog board? I will keep the new power supply. Any tips will help.
Thanks, ShopJimmy!
I have a samsung UN39EH5003FXZA that shows a standby light when the TV is plugged in, but no functions or lights work. The TV worked fine until I installed a firmware upgrade, when the upgrade was finished the tv turned off and will not turn on.
What do you recommend for trouble-shooting?
many thanks
Ralph
I have this exact make and model and originally figured the power board was my issue as l had not a power/standby lite, no leds lighting, no sound/picture, I ordered the power board and just received it today.(great service by the way real fast delivery) Now with the new powerboard in l am seeing the power/standby lite and when it is powered on l get a chime, the LEDs illuminate momentarily and l can see the indicators on the screen but then it shuts off and repeats this every 5 or so seconds. I can see all the led back lites are working but only momentarily. I have just ordered the main board as l am assuming this is the problem now any direction would be appreciated.
Did this fix it? The motherboard replacement?
Mine does the same, turns on screens lights up and then shut offs. This repeats unless i unplug it.
@@RobertYayo no..have new mother board and power board but not working. Under the bed till l toss it.
@@davebl9645 try the little ribbon that connects to the motherboard replace that
Thanks for the great videos!!! I have a TCL 50” smart tv. 50S434 model. I have horizontal thin black lines on the lower half of my screen. Everything else works fine.. I only see 1 control panel in the center of the rear of tv.. could this be my problem???
I would like to know what is the white rubbery material around some of the parts on the board.is that ok to be there.
Thanks for the video information, really appreciate it. Although it was very informative, I took my LED TV apart (UN50F5500AFXZA) and could not find no capacitor, electrical connection, or anything abnormal from either the main board or power supply board. The next task I will be doing is plugging power and reading voltage out of several components to see if I have power going out to such. Besides this, anything else you recommend?
I am definitely not buying another samsung and or paying for their repair center to fix it. Anything else you can recommend, please do so. Much appreciated; Sal
By the way, the problem with my TV is, I get no screen, the Standby LED does not remain on, when I press remote control, LED blinkers as if receiving signal from the remote control. When I disconnect everything, and only hook the power, the power LED stays on, I turn TV on, it works. But after connecting the rest of the cables and watch TV for a little, after turn it off, it goes back to no-work status and the same thing happens (power LED is off but blinkers when remote control is pressed, TV does not turn on). Hope it makes sense...
@@smendez725 Did you ever find out what the issue with the TV was?
Most likely and almost always it's the capacitors in the power supply that go bad. Capacitors tho sometimes they do swell up don't always. I just replaced about 9 capacitors in an amplifier and none were swollen. This is due to Chinese POS capacitors. If you look on the net theres a whole write up about caps and how the Chinese ones are made. They don't use the proper electrolytes internally and in turn they degrade much faster than high quality caps. One thing to note about capacitors is that on the side along with the voltage which can go higher but not lower than stock. Is also the uf or microfarads and also the temperature. The operating temperature that is optimal is 105° temperature. This is due to the fact that that is the operating temperature point where the insides liquify. Or begin to swish around. Being that 105 is the highest they can operate they only come in 105° and 85°. Therefore a 105 cap can run hotter than an 85. This means that it will take much more heat to get the cap to liquify and begin to lose it's value in uf. This also is important because shitty Chinese caps don't have adequate sealing rubber and this causes them to leak and then they permanently lose their value in uf. Causing the issues you guys are having with your tvs. These types of issues don't just plague tvs, they plague anything with a capacitor inside. The reason tvs have this issue is because people leave them on for hours and hours and guess what happens? The caps get hot turn to liquid and lose their value. There's no tv that this won't happen with and personally I've had Samsung tvs that outlasted all others. If you truly don't want this problem with your tv. As soon as you buy it open it up and see what kinda caps are inside. If they are cheap shitty Chinese caps and you can look on the net to see what brands are shit and what ones are good. Replace them as soon as you buy the damn thing. There are other inherent problems with capacitors also that are made wrong. Like the electrolyte has too much water in it which in turn cause corrosion and other issues like leakage sooner than normal. If you replace these caps before this happens even with a much higher voltage you will never and I mean never have these issues. Especially if you replace them with good american made capacitors. Or even good japanese capacitors. There are lots of good caps out there not all american ones are top shelf either. But replacing shit crap caps with high quality caps will save the life of your tv. Caps filter the signal either ac filter frequency or dc filter voltage I believe I can't remember at the moment. And when this no longer happens it can cause other components to begin to fail. Usually semiconductors. And there is no need to replace the entire board. Caps are cheap guys if they have a stripe on one side they are bipolar meaning they have a + and a -. The negative is the stripe side of the cap and on your circuit board is a mark of some sort. To show which side is negative. EVERYTHING EVER MADE HAS SOME SORT OF MARK ON IT DESIGNATING THE NEGATIVE SIDE OF A BIPOLAR CAPACITOR. if there is no mark to designate the negative then there most likely isn't a stripe on the cap. In this case the cap is just an electrolytic capacitor. And there are other types of caps that will work in it's place also. Some are better than the ones they use for tvs. Like polypropylene or mylar. And there's also ways to read these even tho they put the uf in different terms like some will say J on them. Or other letters. But on the net there is a primer or some sort of key as to how to read them. Guys this isn't rocket science, these letters are just like bytes, kilobytes, megabytes, gigabytes etc. Each letter designates either an up or down in values. Usually in decimals. And if you don't know how to read that they have converters that will show you how to do this or what other caps can be used or which ones are good, better or best. A good place to start looking for this type of cap or also a key to look the values up and also calling customer service is PARTS EXPRESS! They have a 1-800 number I believe is 1-800-express. And 24 hour a day customer service that will assist you in making this choice for parts. This shit is so fuckin cheap it's not even funny guys. You can literally replace every cap in your entire tv for prolly 30 bucks. And a new board will run you about 70 to 100 bucks in most cases. Depending on the brand, age and how rare it is. Take the time to buy new caps and try it. The ones I replaced in this amp looked completely normal. But once I got them out you could shake one of them and feel the wrapping junk inside shaking around. That means all the electrolyte is gone. That cap is trash but it's not swelled. I read that this is because the shitty seals they used inside leak when it turned to liquid on the inside. So it's not necessarily that it turns to liquid that makes it bad. It's that it leaks while it's liquid. Now some have to be replaced with the same temperature and I can't remember which ones do and which ones don't off the top of my head. But you know who will know? Parts express customer service. They have knowledgeable sales and service staff that can help you all day long. Take my advice replace the caps and try it even if they don't look bad. The guy saying there are none doesnt know how to identify caps. They come in different packages and different shapes and sizes. And once you've done this once or twice its easy as hell. And your tv will work for years to come. If you replace them when they are new and or put a small fan on the back of the tv to keep it cool so that it doesn't run hot to begin with that tv should last forever. In the electronics world caps are the only item that degrades simply with time. Resistors don't semiconductors don't inductors don't nothing else does besides caps. So if you put some good ones in them when they are still fresh and everything works. Or at least check them to see if they are crapola caps and replace them with good ones. The tv will work forever. Now leds going bad is another story altogether. Leds are just a diode that's also a light. They come on strips on the inside of the tv and can be purchased off eBay in sets for your individual tv. You can make them light up with a 9 volt battery by soldering wires to the tips of the battery and then using the battery to touch the contact points of the leds themselves or the end connection at the start of the strip. Altho the whole strip may not be able to light up with only 9 volts. Best way to do it is by looking which is + on the strip and which is negative on the strip and realizing that positive in on the strip goes to the positive of the first led. Then coming from that same led is the negative on the opposite side Simple. Take the battery and take positive and touch it to positive on the led and the negative to the other side of the led and boom it should light up. Once you Figure out which lights are bad, you can then replace them individually. And you can replace them with anything. Get an led light bulb even if the color is different and they don't look the same they will work. If it's superbowl Sunday and the big tv in the living room is out in a pinch you can replace these with anything that has an led in it. And they are wired in a series. Which means like old Christmas lights when one goes bad they all stop working so you can literally just make a jumper to jump or connect the positive and negative that we're hooked to an led together and it will start working again. Superbowl is back on in 10 minutes. Folks I taught myself this shit by sitting down and thinking about it a little bit. The more you learn about electronics the more you'll realize there's nothing to fear when you have a broken tv set or any electronic device. You can't break it it's already broke. So anything you try is called LEARNING. Sit down and fuckin tear shit open. Im no genius, im just a guy who isn't Afraid to tear the tv, washing machine, telephone, amplifier etc apart to see what the fuck is wrong with it. And eventually you learn that it's not as hard as you thought. House hold electronics steps voltage down because 110 isn't needed in most modern devices. Car electronics step voltage up because when house hold voltage steps down it doesn't usually step down to 12 volts. And see household voltage is fairly steady. Where as a car depends upon the alternator to produce current and if the motors not spinning at 3k rpms then guess what? There not enough voltage. But your house doesn't have that motor to spin that alternator. So it can produce that voltage even steadier when it's stepped down. Every half down in voltage creates a double up in amperage. LEARN!!!!! Rock on people\m/
amazing video. all the info you need before replacing tv.
I have a Samsung UN40EH5000FXZA version TS02. Standby light is on but intermittently will not turn on. Sometimes works fine for days or weeks, then acts up. Thoughts?
Today my SAMSUNG would not turn on, even though the standby light was working and it made the turn on chime sound when I was trying to turn it on. It was all due to a defective 1,200uF 25vdc electrolytic capacitor. You could immediately see that the top of the capacitor was bulging. I replaced the capacitor and it was as good as new. Years ago I had random turn on problems with the same TV, but at that time it was due to oxidized connector contacts. All I had to do was unplug and re-plug all of the internal connectors several times, That had fixed the problem by having scraped off the oxidization. Anyhow, this TV has been working now for 11 years and it works just as good as when it was new.
I have a UN55J6201AF with the same board layout. I tested voltages across the connecting cable and got similar numbers but when I disconnected it, the LED’s did NOT come on. Does this mean the power board is bad, or the LED’s ? What do you recommend?
How much would it cost to purchase a power supply board for my TV I had earlier commented about?
Do you have any videos on troubleshooting a Aquos Sharp television? My television is not working and I tested the fuses which is functioning. I am not certain what could be causing the tv to suddenly stop working.

I have a samsung UN55FH6003F tv. Issue started with the tv not wanting to power on. Solid red stand by light, no blinking that I have seen. If you waited for a while or unplugged the tv for about 10 minutes, it would turn on. That worked for a couple of weeks, but now it won't turn on at all. Using the remote or the button on the tv has no effect. I replaced the power board, and have the same exact issue, no change. Is it likely the main board?
I've used magic power module before and it worked but now there's no power anymore but if I remove the cable connecting to the main board the backlight will start and then if I put it back it won't on. And no standby indicating. Is it that the main board is dead?

I have a Samsung LN-S4051DX that won't power on. It just clicks and has no standby light. I've tested all caps and they are good. And when I test the power board, I am getting overvoltage. Where the 13v pin is, I get 18v until it clicks, then it goes down and comes back up to 18, then repeats over and over. The three 6.4v pins are at correct voltage until the click, then they go down and come back up. And last, the 12v pins all have 26v, then drop down and back up. Board looks good. No burnt spots or cold joints. Sounds like a humming noise coming from transistor the whole time it's plugged in and clicking as well. Any ideas?

Have 2 Samsung UN50ES1650FXZA both with same symptoms. When you plug tv in standby light is solid once power button is pressed light does 2 short blinks, 5 times then stays solid and repeats. Visual inspection of all boards is good. Unplugged main board from PSU LED will come on. Testing plug on PSU to main (5v pins) getting 7 volts but jumps with blink of standby. If I plug tv in and do not press power button standby light will stay solid with screen off, and same plugs shows 0 volts to main.

Hello, I have a Samsung model HL72A650C1FXZA and last night the picture was real dark and now today I tried to turn it on and I hear the music but blank screen and the green lite flashes for a few seconds then a red and green lite flash once then back to just green lite flashing and I can't turn it off or anything. I looked for damaged capacitors but did not see any on the power supply card. Oh, and I already had the LCD replaced because of all the white dots. Any ideas????? Thanks
Hello, After purchasing a new Samsung remote, installing new batteries, and draining the power from both the TV and the remote, the remote still will not power on/off the TV. I tried to use the jog switch to reset the TV, but I need a remote to enter the PIN. Then to make everything worse, I accidentally locked the panel key- now the jog switch is useless. Is there a way to unlock the panel key without a working remote? model # UN50H5203AF- MH01
My Samsung Smart T.V. LED Model Number UN55J6201AF was purchased 2 1/2 months ago and it just shut down, there is no power and the standby light isn't lit either.....ANY ADVICE or DO YOU KNOW WHAT COULD BE WRONG...
My Samsung LN40D630M3FXZA stop displaying an image, I can
turn the TV on and off and the stand by light stays on and will blink if I press
any buttons on the remote, while the TV is on the screen will flash very dimly.
This started after having a non-powered external USB drive connected
for an hour that had water damaged and wasn’t fully dried. The TV was working
connected to the USB for an hour before it began acting this way.
There doesn’t seem to be any damage components on the Mainboard
and power supply boardDo you think only the Power supply board would be effected?
