So do you have a dark image (like no backlight) or no image but backlight?

Either way, check visually for bad caps and post pics of the boards.
Check to make sure voltages from the power supply all check out.

Let the TV cool down, the use the hair dryer to heat up the board for 3~4 Minutes, then trying the TV ON. Start by heating the power supply board first. Just repeat on the each board after the board cools down before moving to the next board.
