The most common problem found on FixYa for Audio Videounit says overload - 2_bing.gif 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 just purchased a used Denon AVR-3200 and have nothing hooked up yet but plugged it in on my kitchen counter and upon turning the unit on, noticed the error overload button was lit up but the unit did not...


Hi

I've had an AVR 3200 for about 10 years - occasionally (maybe once every 6 months), the error overload button comes on... for no real reason than i can detect (ghosts in the machine, maybe)... rebooting has always fixed it for me.

When i turn the power on my receiver it turns off in about two minutes = overload, this occurs when nothing is even hooked up to it.


If no speakers are hooked up to it, then the unit has internal damage. It works only until the damaged portion overheats. The safety relay trips in order to protect the rest of the receiver. Take it to a qualified technician. Even if the speakers are disconnected, make sure no cable leads were left in the connectors, shorting the output.

Unit plugged in but nothing hooked to it overload light and alarm comes on


I am confused, you say something is plugged in BUT nothing "hooked" to it, what do you mean???

Possibly the capacity of the UPS is too small for your PC / monitor etc.

Ran for about 15 minutes. Hooked up to one


Ether the unit is overloaded or the internal battery is given out, or the overload circuit has failed there are only 3 problems that it could be. Not to go to much in depth on this unit APC does have a garentee and I trust you will call them and tell them this exact same issue if they find the unit is faulty they will replace it even though it may be out of warrenty if you get them on the phone and explain to them they will help I know a Greg over there.

Overload flashs


there will be 6 amp circuit in your receiver. you can't unplug them one by one. with a multi-meter you may be able to find the shorted channel. (most JVC receivers use discrete circuits instead of an output IC) Check for shorted transistors attached to the heat sink. You will possibly find some open resistors also. Generally this is a job for a pro.

I have a Pioneer receiver (Model # VSX-1016TXV) and the MCACC indicator is flashing. The manual says to check for loose strands or loose wire speakers. I have completely disconnected the unit from all...


can you tell if its a error code. Also what kind of speakers are you hooking up and what connector style?

if there is a short somewhere this could be your problem as it seems that on this model it is the overload protection. So it may have been overloaded and needs to be serviced or you need to ensure there is no short. if you can provide me with more information i will be glad to be of more assistance.


thanks,

Nate
