NEXT
- CHECK AVC-LAN CIRCUIT BETWEEN RADIO RECEIVER AND STEREO COMPONENT AMPLIFIER
(see AVC-LAN CIRCUIT BETWEEN RADIO RECEIVER AND AMP ) If the AVC-LAN circuit is operating normally, proceed to the next step.
NEXT
- CHECK RADIO RECEIVER ASSEMBLY
- Check that the malfunction disappears when the radio receiver assembly is replaced with a normal one.
OK : Malfunction disappears.
OK : REPLACE RADIO RECEIVER ASSEMBLY
