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 can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.

My sony shake 55 keeps saying protect eos when powered on, why?

Hi the link below is Sony esupport and you should find your answer there,
. The 1st solution I copy and pasted here..
  1. If there has been an electrical surge or power outage, then the internal surge protection inside the home audio device may have been triggered to protect the device from the surge. This is normal. To reset the internal surge protection circuit unplug the AC power cord from the wall for at least 30 minutes.

How can I get Dynex TV out of "protection mode"?

the protected mode kicks in when there is a safety issue with the receiver. This usually comes from an overload to the system via a short in the system or perhaps a surge in power. Your receiver shuts down, and you'll need to shut the entire system down to fix it.
In some older homes, some of the wiring doesn't deliver the "cleanest" power, delivering minor power surges to the items you plug directly into the wall. If your receiver is plugged directly into the wall, purchase a surge protector to stop this

Have a SONY DAV DZ370 Home theater system. Displays 'Push Power Protect'. Tried 'cold reset' and all the manual stuff to no avail. Should I reset the M16C micro-controller or is there...

Push power protect is an indication of an output failure ( Amplifier ). The Home theater system is asking you to switch off the power to prevent further damage. This mode is called protection mode and you will need professional help sort it out.

Hello, if you have the manuals, go to page 54 or at this site if not try resetting them, for the 10av. It says to unplug it, plug it back in(I'd wait like 10 secs), then press clock set-enter-on/off at the same time. Keep in mind when you reset you will lose all saved information.
Ok, This is all I found so far. I would try the reset instructions on both units. I can't find the manual for the ZX 10D.

Sony XM-D1000P5 in protective mode

Sounds like a wiring short somewhere in the powerline from the battery to the amp. I'm guessing the fuze you're refering to is the one inline from the vehicles' battery to the amp. You'll need to find the short, fix it, then replace any blown fuzes before the amp will power up. Just take your time and go over all the wiring to and from the amp. Make sure the battery power cable hasn't shorted against the firewall(use a rubber grommet here), no screws have gone through it while reinstalling interior panels, and that your amps terminal connections aren't grounding out against each other due to stray copper strands.

Sony STR-V333ES repeatedly clicks when i try to power it up. is there an internal fuse???

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.

HCD-XG500 it says push power protect

Power protect tends to mean the main power amp chip has "blown" and needs to be replaced. It only costs about 20 dollars (10GBP). If you are handy with a soldering iron it is easy to do (after you get the thing to bits !) It is the big black thing on the big heatsink inside. The Sony part number is STK442 - 130. Seems a waste to throw the whole thing away for the sake of 10 pounds !. Hope this helps. Nik Howell (
