Problem "protect" whenever i try to turn it on, it says "protection" then it turns off right away by itself. anyone know how to fix this problem? Reset dont work.... =/

Right. This means that either you have a short in your speaker cable somewhere or the short-detector circuitry inside has problems. Disconnect all speaker cables and turn the receiver on. If the symptom goes away, turn the receiver off again and connect one of the speaker wires. Repeat until it starts to go into protect again. When it does, the last speaker you hooked up has a short somewhere in the wire.
If protect always comes on, you'll need to get the unit serviced.

What size is the amp and how many watts is the speaker(s) you have it ran too? If your speakers are trying to pull too much power from the amp it will turn itself into protect mode to keep from blowing a fuse as well as if you are pushing to many watts into small small speakers it will do the same to protect from blowing the speakers I would recommend turning the settings on the amp down slightly and then trying it out also make sure your wires arnt crossed adjusting the setting as it plays is the easiest way to fix the problem also make sure the bass isn't all the way up on your head unit

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

The protect has come on because it senses an output load problem, Turn the unit off, unhook the speakers and wires from the stereo, now turn the unit on and turn the volume down as far as it will go, this should reset the processor ic, if the word protect stays off you have a short in the wiring or bad speaker. If the protect comes back on with everything unhooked the problem is in the audio output ic pack in the stereo and will require a technician to remedy.

Plug it back in WHILE HOLDING the POWER key.

Turn the reciever on for a second or two and then off before the protect mode shows up on the monitor. Repeat this step about five times and check to see if the reciever does not go into protect mode. If it does go into protect mode try it again. Dont know if this is the proper way to fix the reciever but it worked for me. Good Luck

Fixed it by replacing a burned resistor.
100ohm 1 wat designation PR010 on the main pcb.

Microsoft Word document protection has some features that will cause a document to be opened Read Only by anyone except one specific user, so if you have that turned on... it could cause your problem.

So on your home machine, go to Tools->Protect Document... and disable any document protection you have enabled there, then try and bring your document to work and opening it. If you need your document protected, try to see if you can make the protection password-driven only, and not have any user-driven protection.

I ran across this problem before, the only solution the guy found was resetting the receiver, here''s how to do it:
