You didn't post the Problem.
1) Yamaha PSR-2100 Keyboard won't turn on
2) Certain keys on keyboard will not work
3) Volume does not work
4) Won't eat it's vegetables. (Just seeing if you were following along, lol!)
Yamaha PSR-2100 will not turn on, when Power On switch is used.
A) Bad Power On switch
B) Bad DC - DC circuit on the motherboard.
(The AC adapter you have converts AC power to DC power. DC power goes into the Yamaha. From there it goes to the DC - DC circuit on the motherboard )
Certain keys will not play on the Yamaha PSR-2100.
A) EACH key is connected to a Capacitor, or Capacitors. If one is bad key will not work.
Suggest see if the motherboard uses Electrolytic Capacitors.
(More specifically, they are Radial Aluminum Electrolytic Capacitors)
IF, Electrolytic Capacitors are used, see if there are visual signs of capacitor failure. The following information applies to ALL Electrolytic Capacitors, not just ones used on a Personal Computer motherboard,
