Hope the TV have problem with the either power board or the lcd panel. Try to check the power supply is its produce correct voltages mentioned on its connectors if you need help then check the video for that. if the power supply finds ok then you have problem with the lcd panel. In lcd panel there is a some ics which used as the driver of the pixels. the tcon sends data to these ics. and if any onf the ics draws more current from t con board then it can dame the t con. They are not replaceable one ,its integrated to the panel. if its faulty then you have to go for a new panel for that tv. And it would be a expensive repair.

My Phillips 47 LCD TV is loosing picture but is keeping sound.


Main board feeds the t con board. However try the flash light test on set because it might just be the inverter board that powers the backlighting.

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.
