I own this model and found if powered from an isolation transformer type surge protector, with other equipment, this may cause insufficient line voltage to unit. Try plugging directly into wall socket, if that was the case. Otherwise, protect indicates problem with circuit, take to prof. tech for check out.

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? [email protected]


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.

My sony str-d1o15 says protector


Follow the steps below to troubleshoot if the word PROTECT or PROTECTOR is flashing on the A/V receivers display.
  1. Check the speaker wires and speakers for proper connections.
  2. Reduce the volume level. IMPORTANT: If the receiver is played back at maximum volume level it may enter the protect mode. Maximum volume listening will cause the receiver to run very hot and may drain the output capacitors.
  3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.

Sony STR DB-930 Receiver jumping into protector mode


I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.

Re Assembled unit and it worked OK.

I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.

Thanks for the technical help, sure solved my problem.

Regards

Darryl.
