A simple method to check the power board:
Turn off the power and disconnect the cable connection between the power board and the motherboard. Then turn on the power and observe the backlight to see if it is constantly on. If it is, the power board is good. If it is not, either the power board is faulty or the backlight is faulty
Tips for repairing TV:
The power cycle, backlight switch, lines on the screen, or absence of pictures on this model are due to poor screen performance. Replacing the power board does not solve these problems.
If you need to cancel the purchase, you can respond before we ship it, as we cannot cancel the transaction after we ship it.
• If your TV doesn’t turn on, it could be the power supply board.
• If you see very dim video or no video on the screen, but you know your TV has power and is on, then the power supply could be bad.
• If your TV turns on and then shuts off quickly, it could be your power supply board.
