STR-GA9ESG Sony Receiver - displays "Protector"

[L Mehl]

Hello --

This message started displaying a few days ago. Approx a year ago one of
the speaker channels started popping, so I changed Balance to 100% on the
other channel.

The operating instructions booklet only mentions the display, but offers no
troubleshooting information.

Is the "Protector" problem expensive to fix? Is it worth fixing this unit?

If it is a board-replace fix, can anyone suggest which component(s) to look
for, a supplier for parts and service manual?

Thanks for any help.

If it does this with ALL the speakers disconnected then one of the
output channels has a problem. The unit needs troubleshot to the
component level and repaired. Any good technician with the service
manual in hand will be able to diagnose and repair the unit.

Until you get an accurate diagnosis and estimate, there is no way to
know if you think the unit is worth fixing.

Call any Sony authorized distributor for parts or service manual, like
TriTronics www.tritronicsinc.com. etc.

Nevertheless, an ES model ought to be worth fixing. My experience on these
is that usually a driver IC is bad, such as an STK350-030 or the like.
Shouldn't be too expensive if this is the case.
