More than likly the built in amplifier is dead and its time to lay it to rest. Before you do that, make sure all your positive and negitives are correct and that none of the wires are touching one another.

I have a Sony STR-SE591 Home Theater receiver. As soon as I turn it on, it goes in to "PROTECTOR" mode. Nothing is hooked up to the amp at all, besides the power cable of course. I am no expert at all when...


could have a blown channel or a bad connection, these where often riddled with connection problems,
get a powerfull magnifier and look for connections that aren't solid and redo them. also check the outputs first for shorts if none amp is probibly ok.

Flashing message on my reciever


PROTECT, PROTECTOR or the letter P is flashing in the display of the A/V receiver. Solution
sp.gif sp.gif 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: Ifthe receiver is played back at maximum volume level it may enter theprotect mode. Maximum volume listening will cause the receiver to runvery 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: Somereceivers provide compatibility with the higher sampling frequenciesthrough alternate connections. Consult the owners manual for specificinformation.
  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.
