The most common problem found on FixYa for Audio Videomy receiver said amp failure and wont turn back on - 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.

Mum pressed some buttons on amp now the amp wont respond to the original remote or the universal remote. buttons wont work, batteries good and lights up. is there a button that blocks ir signal?


Looking at the user guide it appears that the amp has a standby mode.

See not below on turning standby on. Question can you see the standby light flashing.

I would also suggest using function on the amp to remove any possible issues with the remote.

One would expect the system to return to normal operation by pressing the power button again. If not what do you see on the display.

Note:
Press 1 to turn on the receiver.You can also turn on the receiver using 1 on the remote control. When you turn off the receiver, press 1 again. "STANDBY" flashes on the display panel. Do not disconnect the AC power cord (mains lead) while "STANDBY" is flashing. This may cause a malfunction.

Pioneer sc-lx83 wont turn on. After a short circuit of speaker cable amp does not turn on? what is the circuit reset key combination anyone knows?


This is mostly the receiver going into safety-mode and shutting down.You can try if your receiver comes back on after disconnecting the powercord for a while (10 minutes should be sufficient). If that isn't the case, the receiver will most likely have blown a fuse or (an)other component(s). The only thing to do then, is to bring it in for repair.

Sorry but it does sound like an Amp failure and testing the unit for other electronic component failure will be needed

I bought my fender frontman 15 about 5 months ago, and yesterday i was playing it and it just stoped to work. Now the amp wont turn on... what can i do?


On the back of the amp, where the power cord plugs in, there is a cover that holds a 500 milliamp fuse. Check that.

My amp, was working fine last night, it wont turn on, and i tried switching guitar, cables, even power supplys and still wont turn on, i heard a pop last time i used my amp, and then the signal was lost...


The unit will require repair and if you are not adept at electronics, you will need to take it to a shop. Likely there is failure in the power supply or amplifier that has blown the fuse. Replacing the fuse WITHOUT repairing the cause MAY do additional damage.

My receiver gives me a PROTECT message when i turn the volume up to high and it shuts itself off what does this mean? this started after i hooked up a subwoofer


There is likely a problem in the power amp section that only becomes apparent when the increased volume demands sufficient current in that stage to push the amp into a potential component failure situation. The protect circuit clicks in and disconnects the speakers from the amp to protect them from damage should the power amp stage experience a catastrophic failure. Unless you are a trained technician, you should have the unit repaired before major damage occurs.

My amp wont turn on


first check the fuse located on the back and if your receiver does not have a fuse on the back then open the receiver and check the fuse inside. 80% of the problems are fixed by a fuse replacement

Stand by button flashes but receiver wont turn on


I have vsx-d812 that has an AMP ERR in error menu. the troubleshooting was found to be Q696 and Q697 in the DC prot. area on "C" board, up near front toward diplay in center of c board. You can get access to error codes on VSX pioneer unit by pressing "enter" and "adv. surr." simultaneously for 2 sec. The display should show what error code you are experiencing. I believe there are three diff. error codes. 1) AMP ERR 2) OVERLOAD 3) BOAD ERR (not mistyped) I hope this helps pinpoint error code for ya.

Standby Problem


No, I think you have a bias problem in the audio output circuit of this receiver. There is really not a lot a user can do to fix this unless you have the electronic know how and know how to trouble shoot solid state electronics. Good Luck
