It's hard from the distance to find out what's wrong. Normally replacing all
integrated circuits should solve the problem. But if there is a mechanical
fault (broken part or cable) or a defective passive part (resistor,
capacitor) it might be difficult to find the reason.

I don't know what you mean concerning the A-110 serive manual. It is still
online. I just tried it.
