My Onkyo TX-SV525 keeps turning off 1 second after I turn it on. Any help please.

SOURCE: amp keeps switching off

There is a problem with one or both of the audio amp circuits. The amp is going into a protect mode as to protect and save your speakers. Sorry but there is no simple fix. this will need to go to the shop to be diagnoised. Good Luck

Yes turing on the "A" speaker is required for the Onkyo, but that only turns on the 2 front speakers in the "A" speaker jacks.

You may also need to check and see if the Onkyo has a menu selection in the setup menu that will turn on the sub woofer output on the back of the receiver.

I have seen on countless occasions where people just have a hard time finding that sub woofer option on their receiver.

I do not have the manuals for this Onkyo, so I can not tell you the exact way to find it.

I have been repairing surround receivers since they have been on the market and beleive me, you are not alone in this situation.

Sometimes it seems like you need a Phd. in programming or something similar just to firgure out how to set one of these up.

The solution should be in your owners manual, with the problem then being, just where in the manual. Go slowly thru it paying the closest attention to anything about set up procedures.

I have also seen at times where the setup for the sub-woofer is not listed as sub-woofer, but as "LFE" (low frequency effect) . So keep your eyes open for that.

something else, your sub woofer may have an auto turn on. That means it will only turn on if it detects an input signal. Make sure yo uhave the volume up enough on the receiver to trigger that auto turn on if yours has one.

I would like to have been more help, but without the manuals I can only give you general type thngs to look for. These type of receivers are all so different and all so complicated to operate. The days of just turning on a stereo, selecting your source and turning up the volume seem to be over.

Let me know if you need any more assistance from me.

p.s. Very nice system you have, when you get the Kef working I think you are going to just love this system. and Onkyo has the best quality receivers in their price range.

Here are your options:

1. An electrical problem, where your receiver has a grounding problem.
2. Your speaker wire connections are actually touching each other and that's why your receiver is not turning on.

hi, when the unit shuts off by itself, it means that the protection circuity inside has been activated. it can be a problem with the receiver itself or it is just detecting something hooked up to it that can cause possible damage so it shuts off.

you would need to disconnect everything from the back and by itself, try to turn it on, see if it will stay on and then crank the volume way up to max. if it stays on, the receiver is ok and you then need to rehook your devices one by one starting with the speakers until you determine the one causing the receiver to shut off.

however, if the receiver shuts off and won't turn on even by itself, it means that the problem is internal and it either has to go back to your dealer for an exchange or it has to be sent to a repair center for servicing.

hope this helps a bit.. ^_^

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.
