If you are unable to remedy the 
problem using the 
troubleshooting guide
Clearing the receiver’s memory may remedy 
the problem (page 28). However, note that all 
memorized settings will be reset to their 
factory settings and you will have to readjust 
all settings on the receiver.
If the problem persist
Consult your nearest Sony dealer. Note that if 
service personnel changes some parts during 
repair, these parts may be retained.
