Remove the Power Supply cable to Y Main board and check the Vs voltage in Power Supply board.
1. Vs voltage is OK, replace the Logic board or Y Main board.
2. Vs voltage is NG, replace the Power Supply board.

SOURCE: sound yes, but no picture on tv

If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

SOURCE: no sound no picture went blank .

Do not panic! Do not throw your TV away like I wanted to! Here is what may be the solution for most of the members who have posted their complaints here recently. I am not an expert, but I followed all blogs from various websites and forums, and the conclusion was the same;replace the convergence board for this model. I purchased it from www.partstore.com and since this Akai is the same model asa comparable Samsung Model, buy the Samsung comparable Convergence board for $77. It came to about $85 after shipping. Call them if you need the exact model #. The Convergence board has two black STK ICs and two colors of wires, a gray kind and a blue kind,all which have 'pins' and can easily be unplugged from the circuit board in the TV. It is basically a complete system that takes less than 30 minutes to install. It is a simple swap procedure, with no soldering.You only need the new board and a screwdriver! Remove the lower backboard of your TV where the cables are plugged in (do not unscrew all the screws for the screen, as it is unnecessary, and might just damage your screen if you are not careful.) It has a u-like shape and comes off easy.Detach the gray wires connecting your old board to the rest of the circuitry, and detach the blue wires connecting the old board to the circuitry. On the old board, there are connectors marked,from left,blue, green and red. Detach those from the old board, and mark the wires so that you may connect the correct the wires to the new board. You then unscrew the only screw connecting the board to the TV,and unhook the board from the TV. Hook the new board to the hooks which held the old board, and screw the lone screw to the board. Plug the gray cables from the new board to the connectors where the gray cables from the old board were,and do so for the blue cables. Connect the multicolored cables to the blue, green and red, just as was done on the old board. Reattach the cover and test the TV. Please do not replace the two STK ICs only. When I removed my old board, I realized that there was a burn mark, where the ICs were, but maybe it was a fuse.You may replace the ICs only to discover that it was another problem.Good luck, and I wish you all the best in the repairs. I just saved about$100 for a repairman just to show up.

I have a Samsung tv. The picture went out but still had volume and backlight. I watched your video and changed the t con board. It worked! However, now the picture is upside down. Ideas?UN50EH500F


I would guess that either you got a connection to the T Con board wrong or maybe you got the wrong T Con board altogether! You have to check the numbers of your T Con match the old one and that it looks the same. If they do then it will be fitted in wrong assuming that there wasn't an issue with the set before.

I had a Samsung TV with sound but no picture, All the controls also worked. The problem was the T-Con board. Make certain you get the right one, or it will not work.

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.

Samsung lcd


See if it is on all inputs and modes. If so, unfortunately it is because it is a failure of the T-con board on the LCD Panel. If you are lucky, the T-Con board might be available but usually the only way to fix it is to replace the whole LCD panel. This is because the T-cons are rarely available by themselves. The LCD panels usually cost $500-$3000 depending on the model while the t-con is about only 1/10 of the price.
