Power interuptiions When I turn my Yamaha on it will play for a few minutes normally. Then it starts to cut on and off every fer minutes.

It is normal to see this center will go of after a few minutes when it is in tape player mode or CD player but no playing. Only in mode "Aux" and "radio" it is permanently "on" until "off" by hand or remote. . If problem persists in all modes then obviously something is not right with control system. You may try "my" idea - switch off, remove mains cable plug and press remote key for example "radio" like normal control. After plug mains back and check if changed. In my center I have other than yours control malfunctions and I do not blame unit but electronic interference or mains voltage defects.

Check out the coil. When a bad coil heats up it can become open circuit - closing up again as it cools.

It sounds like you have a part overheating and failing, then cooling off and starting again. i would take it into the nearest Yamaha repair facility or contact your local authorized repair to come take a look before it goes out of warranty.

Try cleaning the side stand switch, the chain lube covers it and they stick on and off

Your subwoofer has gone bad. It is shutting off the output which is causing the red error light to illuminate on the amp and send it into protect mode.

idiot lites always scan fer a few secs an then shut off theyre supposed ta do that like a car. sounds like a bad fuel pump. take to dealer fer a free estimate to find out fer sure.

Hi,
have you check the filter?

sounds like a flaky power supply or lamp ballast

Mine played for about and hour then cut off. It would cut off randomly after this hour. I initially thought it was overheating but after seeing other people had it happen after immediate turn on it must not be the case. Intermittent problems like this are difficult to troubleshoot which is why I came to this site hoping someone had found a simple answer. I am a technician and will have to do it the hard way. When I find the answer I will report my findings to this site.

the solution #3 should work.. you may want to try again.... first turn off the Breaker to cut power then wait a few minutes then turn back on, then within 6 seconds try (Heated dry)(normal)(heated dry)(normal).. all lights should light up then you know that you are in the service cycle, and the unit should go into a self test and clear the fault. The test take about 30 minutes. let me know if you can get into it...
