B speaker shuts unit down...

Hi, I have had this infuriating problem with this unit for a little while now. My Xbox 360 is connected to the receiver via an Optical cable, and I'm using the DVD input of the receiver. Whenever I want to listen to music on my B Speaker (connected to 2 speakers elsewhere in the house), the amp automatically shuts down and goes into standby mode if the volume exceeds the -20db range. It does this if B speaker is ON by itself or if both A and B are ON at the same time. There is no problem with A by itself though... Help!

    Thank you! It turns out my B speaker wires were twisted and the ends were touching eachother a little. I separated them and now it works fine!

    have a sony legato linear str-vx4 i know it sounds old but was made to last a lifetime, b switch makes things go haywire loud humming, then no sounds at all, lent it to a friend for a party and this is what it comes back like, any ways sometimes it works full out for a couple hours or just 20 min. then nothing when i but b channel on, i know he crossed some wire somewhere cause i've never had a problem before, now i checked wires on speaker hook ups nothing touching a friend said something about re-soldering something but i just don't remember what, i'm still buzzed about the humming noise. thanks

    Unplugged all the speakers like manual said. Ventilation was not a problem so unit is not overheating.

You will have to disconnect the B speaker wires and disconnect the speakers and measure the wire with nothing on the wires as it sounds lkike you may have a pinched wire or shorted wire somewhere, or the B speakers one or both are bad. I am leaning towarods the shorted or pinched speaker wires. I say this because if there was an amp problem, it would happen on the A speakers too as the speaker A and B is nothing more then a switch to turn the desired speakers on and off. Good Luck

How to repair a onkyo A-812XG if a volume is higher the unit is shutdown

Hi Ryan, It could be that there is a frayed speaker wire touching the back of the receiver and when playing at a low level the speakers do not require that much power, however when the level from the speakers increases more power is required and if there is a frayed speaker wire touching the back of the receiver there could be a short causing the receiver to shut down. A way to avoid the frayed wire is to use "Banana Connectors" that the speaker wires goes to and the connector will plug into the speaker posts. Please try the following to see where the issue is coming from. Have the receiver turned off, make sure all the speaker wires are labeled, and disconnect them from the speaker terminals. Turn the receiver on select a source that would give you sound if the speakers where still connected and turn the volume all the way up. If the receiver shuts down than it would need to go to a service center as it is an internal problem with it. If the receiver does not shut down, turn the volume down, shut the receiver off and connect one speaker and than turn the receiver on selecting the same source as before and raising the volume up. If the receiver shuts down, remove that speaker from the post and connect it to another speaker post to determine if it is the receiver or the speaker itself that is giving you the problem. If the receiver should shut down after moving that speaker you know it is a problem with the speaker or the wiring. If the receiver does not shut down, turn the volume down, shut the receiver off and connect another speaker followed by doing the previous test procedure. Keep adding speakers until you have them all reconnected to the receiver as long as it has not shut off while trying the test procedure. After determining whether it is the speakers or the receiver you would need to bring either to a service center to be repaired. To locate an authorized independent service center, check the dealer and service locator at our website:, Thanks, JT

Skylanders giants start the game on xbox 360 saysd memory error use another device or continue playing without saving. Whats going on

There's some problem with your memory unit/harddrive.

Try to turn of your Xbox, and remove the harddrive/memory unit(s).

When removed, turn on your xbox, let it start up, and then turn it back off, connect the harddrive/memory unit(s), and start it again.

Then it should be able to start.

Note: If you have the Xbox 360 Slim, the harddrive is placed at the left of the xbox if it lays down, and you can get it out by pulling back a little thingy on the back of the left side.

hi marnie, if all the power and speaker cables are connected correctly, then you might have a faulty or shorted speaker in the vehicle.your unit is sensing a fault condition. check the impedance of eack speaker connected to the unit from the harness plug. if this does not help then your unit needs to be bench tested.

Xbox 360 shuts off on its own

Hi m8, this is caused by the machine is overheating

you could try installing one of the cooling units that slot into the back of the machine or by replacing the fans inside the 360 for whisper ones (faster rpm)

dont lay it on a carpet and if you have it laid down try standing it up to see if that helps if it carries on doing this then it could be the motherboard overheating.

overheating/board failure: this is more than likely whats happening. you will need to strip down the console and take the mainboard out. take the x-clamps off (both of them) and go over the whole board (paying more attention to the memory and cpu,gpu etc) in a circular motion around 2-3 inches away from the board. let the mainbaoard cool down and then put it all back together. then try again. i guarantee this will probably fix your problem.

When I turn up the volume the receiver shuts down

You should first chech out all the speaker wires, the connections on back of the reciver, and on the speakers and make sure there are no little strands touching. If all thats good , disconnect all the speakers and see if the reciver still shuts down. If it does not, then there is a problem with the wiring or the speakers. If it does still shut down, im sorry to say that the move must have joggled something and there is a problem in the unit. Unfortantly, these are solid state units and have no user replaceable parts inside. It may not be worth repair due to the high cost these days for labor, but for sure see how much an estimate would be first. Good Luck Ps Please dont forget to rate this thread
