Coats 950 balancer help needed

[Junkman68]

Hello all, new to the group. I have a coats 950 spin balancer that just acted up today. The only key on the pad that works is the shift key. I can't set the parameters for the tire to be balanced. Has anyone come across this problem? Parts are few and far between and extremely expensive. Thanks in advance, jeff

probably a good place to start is the circuit board looking for swollen capacitors or something burned or popped
