Panasonic TC-P50X1 shut off while watching movie

TV just shut off. Will not power on with remote or when pressing front panel button on TV. No visual or audible signs of power. I pulled the back panel and there are no visual signs of bad boards. No bulging or burnt capacitors. I verified there is power to the power supply board. All 3 fuses on the power supply board tested good with my meter. Not sure if it could still be a bad power supply board or some other board?

Is the service manual. It will detail how to read voltages at test points and guide what boards to replace.

I see a lot of folk wanting to repair a TV without a service manual. I can't guess why.

At this point I think it's the Main Board that won't let the power supply board turn on. Not worth fixing at this point. Thanks though.

This is where the service manual rules.

Some give tests for a no power up issue. On a Samsung long ago I read in the service manual to unplug some cable then cross some pins to power up and see if the power board was outputting the right voltages. Without the service manual you and I would be working in the dark.
