Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

I have an older model Yamaha HTR 5830 receiver and I want to set it up for surround sound (5.1). When I test the receiver all five speakers give back a signal, but nothing ever comes out of the center or...


The broadcaster of the TV station has to tell you they are transmitting surround sound - sometimes they are just transmitting stereo. Also, the media as in CD's and DVD movies must have surround sound embedded or recorded on it to allow surround sound.

Bose surround sound system cuts off


Hi when you turn on check all your speakers work check connections make sure the wire has no stray strands touching the fault could be in the sub unit this is possible / or your speakers one or more could have gone short circuit due to exessive volume thats if you play loud. Had a party lately .Just joking .Regards kirk

Hi,

Three (3) possible ways:
1. use the audio out of the TV (if available) which would normally be red/white RCA and connect to any of the free INputs of your DVD surround sound system;
2. remove the cable INput of your TV and feed it to a tuner such as those in a VCR or any other device (some DVDs have TV tuners also). The VCR's Video OUTput would go to your TV while the Audio OUTput would go to any of the free INputs of your DVD surround sound system;
3. if your cable uses a box/decoder and has the yellow, red & white RCA, its a matter of splitting the red/white signal to feed both your TV and DVD surround sound system or simply remove them from the TV and feed them to the DVD surround sound system.

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

Good luck and kind regards.

Thank you for using FixYa.

Am I forgetting something?


Your old TV took off the sound before the volume control and the new one takes it off after that control. Not much you can do without going in and doing some rewiring. You could use a VCR for your TV tuner source and then you would be able to turn down your TV sound and still get sound to your surround system. Good luck.
