Hello Mike, I re-seated the connections on most of the boards.

Are you the original owner of the tv and was this tv functional prior to this failure? or did you just pickup the tv second hand or something?

Customer: replied 1 year ago.
Original owner and prior to this there was no sign of anything going wrong with it.

Next step is to:

-visually check all the caps on the power board.

-test all the voltages on the power board multipin connectors during plug in / power on.

If caps are good and voltages are present, then it's most likely the Main board (board with all the audio/video jacks) that will need to be replaced. See the following page for possible match (board must match EXACTLY):

Is there a lay out for the voltages I should be seeing?
Expert:  Mike G. replied 1 year ago.

They will be DC voltages, ranging from 3v, 5v, 12v, 24v. But with these OFF brand tv's there are no manuals, schematics, or tech support from the factory. Normally there are voltages printed on the board next to each pin. Since I can't see your exact board, I don't know if your's has voltages printed on the board. If you can find your 5v, 12v, 24v then you can assume the voltages are good.
