The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

I need help


It shows "protect" because the amp IC is blown. You would need to replace it or take it to a repair center and have them do it. The repair cost is normally from $125 to $150, depending on the rates of the shop. If you do not have really good soldering skills and know how to dis-assemble and re-assemble these type of units, you really should just take it in for service.

Let me know if you need any more help.

My audio system says protect on display


Hi Jean,

Without a brand and a model, best that I can provide are generic possibilities:
1. unplug the unit from the mains for a couple of hours. This is supposedly to reset most systems; and/or
2. check the speaker wires and make sure none of any bare wires are touching each other.

If your concern has not been corrected after completion of the above procedures, pls post back brand and model.

Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

My audio system says protect on display


As Shown Here, A Sharp-Associated Repair Person Suggested Replacing A Specific Output IC, As Well As Two Other Small Components. The Total Of The Three Replacement Parts Is $55.43. I Suggest Doing The Repair Yourself, As The Stereo Would Be No Longer In Warranty, Unless You Have No Experience With Working With Electronics. You Could Also Get The Repair Done By Circuit City, Best Buy, Or A Similar Electronc Consulting Business
