Follow the steps below to troubleshoot if PROTECT or PROTECTOR is flashing in the display of the A/V receiver:
IMPORTANT: If model-specific information is required to complete any of the steps in this solution, refer to the operating instructions supplied with the product. Manuals are available online in the Manuals/Specs/Warranty section of the Sony® eSupport Web site.
NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step.
Check the speaker wires and speakers for proper connections.
Reduce the volume level.
IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
Disable the surround sound option if both the A and B speakers are being used simultaneously.
Ensure the top of the A/V receiver has proper ventilation to keep it from overheating.
If the message only occurs when using a DVD player, the sampling frequency may be set too high.
IMPORTANT: Some A/V receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
Unplug the AC power cord for approximately 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.
