Not much to go on here.. what’s the history?

The connectors on the boards for the main cables have extremely delicate pins like a CPU pins. These bend out of place easily. Have you take apart?

Schematics are difficult to come by on this one. If you need to check anything against a known good board, let me know.

Use cotton ear stick, or fine tweezer with cotton on tip.
