JM intermittent Ball Launch switch

[BurnDizzyBurn]

Just taken my Jonny Mnemonic out of storage, everything is working fine bar the ball launch switch.

I’m stumped, as the switch is intermittent.

I’ve swapped the switch out with a know good switch, same issue .

All other switches on the row are working fine, wiring all looks to be fine but the switch is just not wanting to work most of the time.

In test the switch will register once in maybe every 20 presses.

Any ideas?

Try reseating switch connector at the CPU board ?

Thank you, however, I’ve also tried that but to no avail
