You most likely have a short in one of your speaker wires (+ and - are touching somewhere) causing the receiver to enter a protect mode "Click!". Disconnect all speaker wires then connect and test each one at a time to find the culprit. I've seen this happen with speaker wire or a subwoofer cable that is too small of a gauge. Hope that helps.

I have a SONY STR DE915 receiver home theater amp. After 14 years, it decides not to power up! Are there internal fuses? Can i replace the power supply myself?


There are internal fuses that you can check. This model was notoriously bad for amp problems. These amps would burn up a lot of components when they go out.

I have the same problem. The fuse blows every time I plug the Sony STR-DE135 into the wall. I did not find the F901 at Radio Shack, so I bought a fast acting 5 Amp 125V Fuse at the Hardware store. It blew...


There is usually one or two normal clicks on power-up. A self-protection relay activates after a short delay for circuit and power stabilization plus some internal cheking for shorts and thermal issues.

If it keeps blowing fuses you are stressing it a bit more every time you feed it another one. I'd get it in to a Pro for repair.

Sony STR DE-445 unit powers up but no sound


Check the fuse, Sony is known for its random problems with sound. The one I have you must tap it on the side. Its a flicker switch inside.

I have a Sony STR DB930. Something happend and it


The fuse blowing is a symptom of something seriously shorted internally. What preceded the initial problem? Smoke is bad. Fire would be soon to follow without the fuse blowing. Take it to a tech.

you might have burned up some internal parts, it is very important that you keep your unit well ventalated so that it has less of a chance at overheating, check for any internal fuses that might have blown.

My sony v333es say protection panel power off


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.
