Hello. Can you grab the part number from the power board, please? Are the inverters separate from this board, or are they integrated?

OK with the TV on we need to see if you have 24V going into the inverters. Usually there's a wiring harness with several 24V wires and several grounds. Check the 24V and let's see if the main board and power supply are doing their jobs. Sorry for the delayed response, by the way... this week got crazy.
