Eagle Spectrum Problem

[kcray]

My old White Eagle Spectrum has started giving me coin hits all the time. Free air or on the ground, I get tone and different coin signals after each reset. Sent it to White, but doing the same thing. They say I'm getting stray signals, which never happen with that machine. Tried it at different locations and still has the problem. It's going back tomorrow, as I feel it has a component breaking down. Any one else experience this and do they repair boards any more?
