Quoted from Leo13:I'm interested in the solution of your problem. I have 1 button (+) acting really weird (+ or "Enter" depending of its mood) and I could not find any anomaly.
Define wierd for us.
Debugging info...

The vast majority of direct switch failures are one of three issues...
1. Alkaline corrosion on the MPU. The ICs just left and down from the battery holder service these buttons.
2. Broken wires on the coin door switches themselves.
3. Coke/Beer/Whatever dripped down into the buttons.

Quoted from mrserv0n:Chris, from the picture I took of mine can you see the ICs your referring to if mine look good?
I had a look at them. They look fine. The are U14, U15, etc.
The only thing I saw in the pic was =perhaps= some corrosion on the 10K resistors below the center battery. But the pic was a little fuzzy. The legs of those resistors should be as shiny as all the rest.
