My sony str- is getting a sony protector check code 22. Is that a fuse problem or do i have to get sony to fix it? napa.king@yahoo.com


Unfortunately this is not a fuse problem, as the fuse would burn before the protector check code appears. Probably there is a short circuit and you should take to an authorized sony repair shop. Good Luck.

Error code - protector


Try disconnecting all the speakers from the back and turn the unit back on. If the "protector" display goes away, turn the unit back off and reconnect one speaker. Turn it back on and check for "protector". Repeat.

If you find that one of the speakers causes "protector" to appear, you either have a bad speaker cable or bad speaker. Try swapping each of those out to see what happens.
