@marantzaa we will need to know the exact model for your TV. Remember that it is the main board that tells the power board to turn things on. The powerboard basically turns on and functions when it is in standby mode, as shown by the light on the power LED. A quick test would be to disconnect the main board from the board. If the backlight turns on then it is pretty likely that the power board is okay. Again, we need more information about your model to make sure, but for now, yes, it could be a main board issue.

@marantzaa so when you disconnected the main board the backlight came on and it stopped the weird behavior?
