PROTECT when the volume is turned up to near max, the system shuts down and says "protect", and i have to turn the whole system off before i can restart the system. It only happens with the volume turned up. Are the speakers or woofer too close, or is this a bigger problem???

Well for the issue of the audio it usually protects when you are approaching the maximum that the internal workings of the system can handle. This also happens when it is overheating. Try to limit your maximum usage of the system to 5-10points below may.

Hii I have sony shake 6D system and whenever I turn the volume up it reaches upto 40 and shows the error of 'protect E01' while the maximum volume is 50. Please help

Most likely, your unit is shutting down due to overheating. You cannot run an amp at that kind of volume very long. It is shutting down to protect itself. Try running the amp at 1/3 your normal level. Most likely, it will not shut down.

DVD system shuts down during DVD play with various parts of shows

I think this is the answer you are looking for.

Let me know if you need more help.

Knowledge Article C337191 Error: The message PROTECT or UNPLUG shows in the display.
Follow this procedure to troubleshoot when a PROTECT or UNPLUG error is displayed.
IMPORTANT: The top of the receiver must have proper ventilation to keep from over heating.
  1. Reduce the volume level.
  2. NOTE: If the receiver is played at the maximum volume level it may enter the PROTECT mode. Maximum volume listening will cause the receiver to run hot and drain the output capacitors.
  3. If both the A and B speakers are being powered by the receiver at the same time, turn off the surround sound option.
  4. If protect occurs only when using a DVD player, the sampling frequency may be set too high.
  5. NOTE: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the user manual for specific information.
  6. Ensure the speaker wiring is not damaged and is properley connected to the back of the receiver and speakers.
  7. If the issue is still unresolved after completing all of the troubleshooting steps, service may be required.

Our Samsung HT-C6900W Theater System shut off yesterday and then said it was in protect mode, now we cant get it turn on. This system is only 3 months old. Can you help?

The problem is with the amplifier overheating so the system shuts down to protect itself.

Make sure the ventilation fan is not block or obstructed.

If this is OK then contact your supplier with the equipments warranty.

When i turn the system on the display will read "hello" then "protect" then shuts off. Whats up ?

The "protect" function is shutting the syetm down to protect the electronic components inside it. Usually caused by a lackof earth in the plug or extension lead. Plug it straight into the wall and check it, if it is still the same then it could be a speaker wiring short circuit, disconnect the speakers and plug it in on its own and test it

My system shot down during a movie

The reason why your receiver is going in protect is because there is a short circuit happening. This would either be on your speaker wires, speakers or receiver itself. What you want to do to check would be:
1. Unhook all sources and speakers from your receiver.
2. Turn on your receiver and crank up the volume to maximum, if your receiver does not shutdown or go on protect then the receiver is OK. If it does shutdown and go on protect then its an internal problem on the receiver and you would need to send that over to an authorized service center.
3. Hook up a source and 1 speaker. Play something from the source or the fm tuner, Crank Up the volume to about 46 or 47 volume. If the receiver does not shutdown, its good.
4. Hook up a second speaker and repeat the process until you encounter the pop and shut down
if for example you encounter the pop on the 4th speaker, try changing the speaker wires.
5. If the receiver still shuts down then it would be a short on the speaker itself and it would need to go to an authorized service center.

Protect mode shuts down the receiver

If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Surround sound keeps shuting off

the system go to protect mode in case of trouble in output stage(power output component and cords and speakers.
try to connect each speaker one by one until you find the bad one change cord first for the bad one and check if not working you must change speaker itself.if all above does not solve the problem you must pass your sony to service center

Sony recveir gos to protect it self

The basic reason for your receiver to fail as it does is because of too much heat. Check these:

Is there anything on top of the receiver, bolocking cooloing vents?

Check speaker cable. Make sure no sorts of any kind. A single strand short might no shut the receiver down but it would ne enough to make the amplifier section run too hot!

Are you using speakers A and B? If using both, surround sound must be off.

Have you been running it at max or near to volume?

It also could have been a one time thing so you need to reset the receiver. This is done simply by unplugging it at leaving it be for 2 hours or so. This will thouroughly discharge any capacitors etc that keep minimal power for settings.

There are other solutions such as CD/DVD connections, imedance ratings, etc if none of this works before it needs to be taken to a shop.

After resetting, check these out for your next email (hopefully not!). How hot is the receiver to touch at top? Is it failing with a specific input selected? How long before you get the error message? Does it turn on at all? (if not at all, disconnect the speakers, reset, if still doesn't come on, it needs shop work).

Hope this helps.
