T Con Board or a panel problem? Can this be fixed?

It's not the main board, tcon board or panel, slim chance of it being the power board (5%), it's your LED backlights that have failed, new strips can be ordered from shopjimmy, I'd stay away from ebay for parts

The Main board, T-Con board, or the display panel, , i will get a new T-Con board to try out first.

It might be your "ISL9860" chip on the T-con board, the video was called, "Samsung UN60EH6000 Series T-Con Repair BN95-00628" and is located at:

Yes it's a bit different model number but see if it is close enough to your TV to be useful. He says that models UN60EH6003 and 6050 were the same kind of fix for the no video problem so perhaps your UN50EH6000 is also close enough to the UN60EH6000 model.

He did not mention anything about a sound but it was a no video problem he was fixing. If your voltages are OK on the T-con board then you may want to contact him directly through youtube to see if he has fixed your type of problem. Otherwise this is the first part I'd replace.

Watch the video all the way through because he also mentions some caps that may need replacing as well.

hi so is it totally dead or is there a standby light.if not check fuse on the power board first, these led tvs do suffer from poor solder joints, i'd check solder connections any ring around the soldered pads,if ok you would need to do voltages checks to find out which board is failing, thanks

this is panel problem and it can not be fixed

The t-con board controls the picture. To test it shine a flash light on the screen abd see if you can see an image when the TV is on. If you do then the T-con board is OK. Look at the back light ballast board (sometimes is part of the power supply board) If you see no movement or a dim picture with the flash light, then the T-con board is gone. You can get parts here: TV Parts Universal TV Stands DLP Chips ShopJimmy

If you see a picture with the flashlight you can rule out the T-Con board. It's working. So the led driver board is the problem. TV Parts Universal TV Stands DLP Chips ShopJimmy Go here for replacement parts.

This is usually caused by some tubular capacitors that have gone bad. You can tell visually by the fact that the bad ones have started to swell up. You can check the value for voltage and microfarads and buy replacements at Radio Shack or similar electronics store. While the microfarad capacity has to be the same, the voltage can be the same or higher.
