When pressing each switches (SW6000, SW6001,
SW6003, SW6004), do the voltage of Pin(30)
of IC2000 increase?
Check the switches (SW6000, SW6001, SW6003,
SW6004) and their periphery, and service
it if detective.
Check the line between the RS6000 (remote
control receiver) and the Pin(5) of IC2000, and
