Model: CDX-4090 No. 380
Subject: No Audio. Date: November 10, 1995


Symptom:
(51) The unit has no audio regardless of the source. In some instances the STEREO
indicator on the display may always be illuminated. This problem may be caused by
Q593 being defective.



Solution: Check Q-593, and if found to be defective replace it. Also, change TH503 to a
different type which offers greater protection against damage to Q593.
