Is the function corresponding to
selected signal input selected?
Select the corresponding signal
with the input selector.
No
Check the communication between
the CN4701 and around IC4901.
No
Check the circuit between IC4701 and
IC5001 and replace broken parts.
No
The panel is defective.
No
Check around IC4701 and check the
communications between IC4701
and the microcomputer. If there was
no ploblem replace IC4701.
No
Check around the IC that is found to
have a failure in communication and
the microcomputer. If there was no
ploblem replace MAIN Assy.
No
Replace the MAIN Assy.
