    I already ordered a T-con board and should get it tomorrow. If this is not the problem. What should it be ? I already checked the power board for bulging capacitors etc. At first when i power the tv on, It looks like it shows something then the screen blanks of, I don't know if there is sound or anything since we did a master reset to the tv when it now happened without checking for sound....

    If the tcon doesnt solve the issue then it would have to be the main board.

    I got the t-con and i'm only seeing lines down the entire screen as shown in the picture, a few people told me that i got a faulty t-con board and should get it replaced...The person who sold me the t-con board agreed to give me a refund when i send it back...

    The problem you're having can be from your T-Con, LVDS Cable or Panel. In this case it might be that you did not put the LVDS cable back in correctly. If you sent it back and need another one check out

Sounds like there is a short on the power board or the power board has gone faulty.

Look on the power board to see if any of the capacitors are bulged or if there are any other components burnt out. The TV is going into protect mode because of an over current, which points to a short on the board or a component has gone short circuit.

Television have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them.
Hope this help in solving the problem, Take care...

The T'Con board [Timing Control Board] of your TV has the fault. Check its strip connections for rigidty. If the connections will get loose, when heat up, the fault you describes her can occur. Check it first. If all are OK, repalce it.

Picture has vertical lines (no picture)....what's wrong? It is less than 2 years old. can you help plrease?

Hi Matt, I know it's been awhile, but I'm making one last ditch effort to fully confirm everything you said. To start with, I replaced the T-Con Board, and it didn't correct the problem. My T-Con Board IS ATTACHED as shown in the picture, with the two ribbon connectors. Since it is connected, are you saying DON'T buy a main board, or are you saying since the T-Con is connected to BUY one? Thanks so much for all your help Matt, I wouldn't have been able to get this far without a good guy such as yourself. If I can't repair, I'm going to part out the boards anyway, if the front panel is bad. Please refer to the picture for clarification. Is it option 1, or 2?

1. T-Con Board attached, DO NOT buy main board.
2. T-Con Board attached, DO buy a main board.

Again, thanks so much for everything, I look forward to your final answer. Take care.
