The key operation is not functioning.
Are the contact point and the installation state of the key
switches (SW3000-3005, SW3100) normal?
When pressing each switches (SW3000-3005, SW3100),
do the voltage of Pin(4) of IC2000 increase?
Check the switches (SW3000-3005, SW3100) and
their periphery, and service it if detective.
Check the line between the RS3000 (remote control
receiver) and the Pin(27) of IC2000, and service it if
detective.
