Try unplugging each set of leads 1 set at a time,and after each set of leads are unplugged switch it on as it may be a set of faulty leads,it sounds like the safety cut out is coming on and switching off the power to save your system blowing due to bad or broken phono leads or speaker could also be that you could have blown your output transisters or something else thats causing the saftey cut out to cut off the power,also make sure there are no loose connections inside your mains plug as this would cause the same thing.

If it's a straight-up power switch then it will need to be replaced if it works off a relay then the relay is gone.

SOURCE: Yamaha DSP-A2070 intermittently fail to output audio to speakers

Probably selector switch when you turn to CD mode. The ball bearings inside the switch make poor connection resulting in intermitant problems to either speaker. Yamaha knows the selector switch is defective but has stayed silent. I've had mine replaced for $144.00 Can and it works AOK now. Different switch of course. I've had my problems with that switch for a long time and it was after a few years that a knowledgeable technician knew of the problem. Poor support by Yamaha! I'll never buy a Yamaha product again nor will my relatives and friends. Do the calculations and assess whether the cost of the switch is worth the value of the receiver. I think it is worth it as the receiver when it works is excellent. It is at a stage now when other problems could creep in though including corrosion on the boards and solder joints so have the technicians do a entire quality check at the same time...

SOURCE: I have a phonic powerpod 7. the speaker

In bridge mode, the left and right amplifiers are in essence connected together. Typically, the speaker connections are to the positive connectors for each channel for this mode. WIth the speakers still connected, you essentially shorted the outputs to ground and smoked the output section. The unit will detect this now and not turn on the output section. Your unit is in what is usually called "protect" mode. This unit will require repair. Expect to have the output transistors replaced at the very least. I would estimate around $16-$40 for parts.

SOURCE: yamaha dsp-a492 amp keeps switching

Amplifiers have protection circuits that sense current overloads, and especially internal faults, and theyt shut themselves down to prevent further damage to the unit, until it can be troubleshot and fixed. They're designed to allow minimum damage to the unit, and the cause of the overload must be found and fixed by troubleshooting the unit systematically. Sometimes you can get lucky and ohm out a suspected power transistor or IC regulator and replace it successfully, but most of the time a scope is required.
Take it to an audio repair shop and get an estimate first, but know that they do charge by the hour, and it can get a bit expensive.
I noticed this same problem was posted in a couple of forums on the net, but they never got a solution or followed up, so service is in order.
Good luck, and hope this helps.

NAD C320. Only one channel sounds. Problem with the volume control?

Did you try to switch the loudspeakers? Before changing anything always lover the volume and switch off the amplifier.
Assuming you tested already different inputs, you can be sure no cable from signal source is out or defect. (or did you nit check that first?).
When the amp is switched off, disconnect the speakers and switch left to right and right to the left output.. If the other speaker is quiet now, you are sure it is in the amp. Still his can be anything.
You can check the connections between the pre and main amplifier on the back side. When you have an extra set of interlink cables, perhaps you can cross the in and output there too. Take care every time you change something, lower the voltage and switch off the amplifier. Sudden clicks when switching on or changing anything can damage the amp and or the speakers.

Perhaps when you checked this you can locate where the problem is? Speaker, speaker cable, power amp, pre amp, (only a part of the pre amp.

My machine flicks the mains switch as soon as i turn it on, both washing and drying. it first flicked the safety switch about halfway through a dry load...what could it be?

there is a few things that will do this to your electics 1st & formost if your trip switch is tripping off remember this is a safty device to prevent fire so ignoring the problem & switching the power back on to try again could run the risk of fire!!

This sounds like a heater issue since it's tripping the power on both the wash & dryer, in events of overheating the machine will trip your power for safty & to prevent the risk of fire however since you mention that it trips the power as soon as you switch it on you could have a blocked pump or burnt out motor too if your finding that the machine is tripping the power earlyer & earlyer each time you retry i would focas on the motor or the pump 1st

on rare ocasions you can spring a leak & if water gets on the electrics this will also trip the power but this is 1 of the least likely posabilatys..
remember always get a qualified electrician to work on your electrics to ensure the job is carried out correctly

Hope this helps

Amp powers off after switching on

The DSP-A1 has an internal self diagnostic program which you can access from the front panel. The service manual shows how to do it and what the readout codes mean as far as the fault that caused the trip. Service manuals are cheap and readily available on the web.
