Question about Pioneer Amplifiers & Preamps

No power on a Pioneer A-77X Amplifier

The switched and unswitched outlets work. The on/off switch is good. The four fuses on the power supply board are good. Haven't noticed any burnt componets. None of the front panel lights are on. No audio. Completely dead.

The unit is probably in protect mode. Do you have any electronics repair experience? If so, we may be able to work through this. Let me know and we will try a few things. You will need a multi-meter at a minimum.

Amp would not turn on after power outages (twice in 30 min), I had it plugged in to the power conditioner, it wasn't hooked to the wall outlet.....please advice

Switch off the amplifier for some time and allow it to reset. disconnect the speakers and reduce the volume level before you put it on. If the power does not come on you will need to probe inside. Get help if you are not familiar but check on the power lines coming in for failure of fuse, the secondary power supply section transformer or the smps power. Hope it would not go further to this but check this out.Check for shorting inthe outputs, if so disconnect and test. Good day

I have a Yamaha natural sound stereo amplifier a-760 but it wont turn on????? How do i repair it??

Try these for starters!
Is the power switch broke? Check the power cord! Are any internal fuses blown. Look inside for damage/burnt parts. Are the printed boards broken? after say being dropped? Is the transformer working? Check around the power supply area for faults.
Note - be careful your dealing with mains electric!
