This sounds like you have a bad capacitor on the logic board. This will take a bit of effort to nail down. You’ll need to find the schematics and board view drawings to trace out the voltages. Your other option is getting a replacement logic board.

I don't see any capacitor on the logic board what does it look like?
@elchanan1 - Can’t see the tree in spite of the forest! I would say have of the small SMD components on the logic board are caps.
You really need the schematics and boardview drawings and the skills to work off of them with a DVM to ID the bad one as often there is little to go by.
In the end I replaced the capacitors in the electrical panel and now it works
