In this video we will review how to troubleshoot a Samsung LED TV that won't turn on and does have standby.
In Samsung LED TVs, you can have differences in the number of boards. Most will have a main board and a power supply board, while some may have an LED driver board and t-con board.
This TV just has a main board and a power supply board. Here is the main board, and here is the power supply board.
The LED driver can sometimes be built onto the power supply board as we can see here on this TV.
The t-con board can also sometimes be built onto the main board or into the TV panel.
This TV has the t-con connection here and then it runs into the panel.
Click the link in the video for more information on the basic functions of these boards.
If you cannot power on your TV, the first thing you will want to check is that you have the TV plugged into an outlet that is working. After making sure that the outlet is working, you will want to check and see that your TV has a standby light.
The standby light will typically be blinking or illuminated on the front of the TV.
If your TV will not power on, and you do have standby, then the problem is most likely with either the power supply or the main board.
The first thing you can do is to visually inspect the main board and power supply looking for damaged components.
Here we have a closeup of the power supply. You can look over the board and do a visual inspection, looking for any raised or puffy capacitors or any burnt or damaged components.
Here are some examples of what a puffy capacitor or burnt or damaged component will look like. If you have any damaged components that look this way, you should replace the board.
If there is not a replacement board available you can also try replacing the individual components or purchasing a repair kit.
Removing and installing new components requires the ability to be able to solder.
When looking for damaged components, or burn marks, you can also look at the bottom side of the board. You would simply just need to disconnect all of the cables and then remove the screws that hold the board to the panel.
Be sure when disconnecting cables and removing screws, that you you take a picture of what the board looks like in the original state with all of the cables connected, and then you will have a reference for when you reconnect all of the cables.
Here is a closeup of the main board, you can look over the board and do a visual inspection, again looking for any damaged components. If you have any damaged components, then you should replace that board.
If you do not see any damaged components, then that next step would be to check voltages on the power supply an the main board.
If you do not have the skills or tools to check voltages, but still want to try and fix your TV, you could also replace the power supply and main board, one at a time, and see if one of those two boards, fixes the problem.
If you are going to purchase multiple boards and replace them individually, to see if one of the boards fixes the problem, before purchasing, be sure to understand the return policy of the company you are purchasing from as there may be re-stocking fees for any returned parts, or parts that are not returnable at all.

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. RUclips 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!!!
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.
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!
Just replaced my Samsung UN50EH6000FXZA main board with the this main board BN96-25798A for shop jimmy and my TV works again. Thanks.
Great video - very informative
Hey thanks, this actually helped a lot. do you have any recommendations for sites that sell main power boards for reasonable prices? Thanks again!
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..
Thank you my tv problem is the main board and I ready purchased in your page thank you 🙏
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???
Good! I saw one puffy capacitor on the power supply thanks to your instructions!
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?
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...
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.

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

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.
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
Very nice sir
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.
Your work is good
amazing video. all the info you need before replacing tv.
Thanks, ShopJimmy!
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
dear sir i have a problem with Samsung tv 32 inch model : DF320AGH-R2 which is the screen have picture but it's wite and bright. .. i think its the main board .. what should I do? !
thanks
I have a model un32eh4003 and need to cut a jumper wire for my TV to stop flickering, which one do I cut?
If a Power Supply bought doesnt fix the problem, can we resend it again to you, and ask for trade it for a mainboard?
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.
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.
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.
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...
Have samsung le37 A557P2FXXU Fault:-

Hello, I have a question for my TV LED SAMSUNG SERIES 5: not work after storm. Function only red led stand-by. What I can check up, 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 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
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/
Can use this method for fixing my DEVANT led tv that won't turn on but it has standby
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?
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?
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.
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 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.
my Samsung 39" led tv has flashing red and back lights. will not turn on.. I unplugged the Led cable from the power board.

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 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.

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 the same problem, did you find a fix?
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

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
