Welcome to the site. I'm Dan, and I'd be happy to help.

Reading over your problem, I'm a little confused as to what the problem is. Can you tell me what the original symptoms were, before you replaced the power board?

The tv won't turn on and the power supply is good

What were the original symptoms, before you replaced the board? What made you want to replace it?

The TV would take multiple attempts to plug in before working again until that stopped working altogether
Customer reply replied 9 months ago
I replaced the old power supply which was not giving the main board any power. I tested multiple parts of the board and there where a number of components not working. I have power to the main board, and to the IR, and Power button, but not to the T-con/ LVDS Connections on the main board.
TV Technician: Dan, Master Tech and Repair Facility Trainer replied 9 months ago

Does the Tcon connect to the power board, or only the main? Have you tested the voltages after pressing the power button, or only with the TV plugged in?
