Question about Sony STR-DE345 Receiver

1 Answer

Protect Mode Goes into Protect mode at different intervals. Opened up component and cleaned out. Also noticed that if the receiver is on and not in Protect mode, that with the cover off if you push slightly outward on the back panel it triggers it into Protect mode. Like a ground problem maybe. Any suggestions?

There are bad connections on the main board that are effected by heat. I would suspect that when the volume level is higher, the system shuts down sooner. This should be a simple repair that will not require parts. If you can solder, you should be able to repair this yourself. If not, the cost will be the local labor rate.

Stuck in protect mode


Speakers shorted out, blew a fuse. Replace the unit or (cross your fingers and) open up the box and find the blown fuse.

Goes immediately into protect mode


Yep. The wiring to your speakers or the speakers themselves have shorted out. You have a blown fuse. You'll need to either replace the unit or attempt to replace the fuse yourself.

Protect mode


You may have loosened a solder joint on one of the components inside with your air blast. A repair tech would monitor the outputs DC offset voltage and he will probably see one that is not zero volts and while wiggling various things he should see a sudden change in the DC offset voltage on the bad channel when he touches the bad connection. Then it's just a matter of resoldering the connection. Good luck on this one.
