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.

After turning on the tv, the power goes on and off automatically


Hi.

The TV goes into protect mode because a internal fault is detected. Protect mode is a forced standby mode that starts when an internal fault is detected. The TV power board supplies power in different voltages. When in protect mode the PSU higher voltages are shuts down. The only PSU line that remains live is +5VDC.

All you can do at user level is turning off the TV and disconnect the power cord for about ten minutes. This will drain power from the TV circuits and can fix temporary problems caused by the accumulation of electrostatic charge in internal components.

If after the power drain the TV still does not restart, then internal components must be tested and repaired. The job must be done by a trained technician. To book a technician or to order parts call the phone number listed on the owners manual.

Regards.

Protect mode shuts down the receiver


If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Sony STR-D611 receiver goes into protect mode when turned on.


I cleaned the contacts on the transistors and it's working great now. Previously, I spilled some drink on the unit and it went into protect mode and it was in the power amp section. It's all up and running again. Thanks for the info. --Steve B.

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.

i believe protect mode is because you have the wrong impedence speakers, they are too low (4 ohm? 6 ohm?) it chols work with 8 ohm speakers

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.
