Customer told me something got thrown at the screen and then the tv went off and it is completely dead, no power LED at all. She said the object was a foam ball and that it hit the bottom of the screen, on the frame not LCD.
I tested the power supply and the PWR-ON is 0V. I checked the voltages on the main board and they are all jumping around. I jumpered 3.5V into power supply board and all voltages come up on power supply, but they are not stable and jump around.
Would this point to a bad main board?
