[carlosnolasco]

Hello, my name is carlos, I am new in this forum. I am sorry if I am not doing the right way to post over here. Please let me know if is wrong in that way I try no to do it again or let me know the correct way to do it. I have a dell plasma tv with no sound and no picture. I replace all the boards, but main logic board and the tv still no sound and not picture. When I replace the power supply board the tv work for about 2 weeks, but after I had lines on the bottom of the tv, so I ordered the y-sustain board, nothing the lower and upper boards, etc. still nothing. If you need more info, please let me know. Thanks in advance

The main board is what tells the power supply to turn on and controls the audio.

Sounds like you need to start with the basics.

Disconnect Z and Y boards check for VS voltage coming from power supply first. Also check for stand by 5v to the main board from the power supply
