The key operation is not functioning.
Are the contact point and the installation state of the
key switches (SW2102, SW2184, SW2186-2191,
SW2195) normal?
When pressing each switches (SW2102, SW2184,
SW2186-2191, SW2195), do the voltage
of each pin of IC2001 (shown below) increase?
SW2184, 2186, 2187, 2189, 2191: IC2001 3PIN
SW2102, 2188, 2190, 2195 : IC2001 4PIN
Check the switches (SW2102, SW2184, SW2186
-2191, SW2195) and their periphery, and service it
if detective.
No
Re-install the switches (SW2102, SW2184,
SW2186-2191, SW2195) correctly or replace the
poor switch.
Replace IC2001.

No operation is possible from the remote control unit.
Operation is possible from the DVD, but no
operation is possible from the remote control unit.
Replace the infrared remote control receiver (RM2002).
Or replace the remote control unit.
Check the line between Pin(1) terminal of receiver
(RM2002) and Pin(25) of CN1001, and service it if
defective.
Is the "L" pulse sent out Pin(1) terminal of receiver
(RM2002) when the infrared remote control is activated?
Is the "L" pulse supplied to the Pin(25) of CN1001?
Replace DVD Main CBA.
Is 5V voltage supplied to Pin(3) terminal of
the infrared remote control receiver (RM2002)?
Yes
No
Check EV+5V line and service it if defective.
No
