    Question Yamaha Receiver turns itself off... Help!!!

    Hello from Byron Bay, I love my old YAMAHA Natural Sound Stereo Receiver RX-570.
    I am no electrician and could only do basic work. Although I would spent up to 100 AUD to get it running again I wonder if it is not "Time to say Goodby..." Here are the 2 problems:

    1. I press the ON-Button. The amp. powers up, lights go on and then it makes "click" and all goes off again. But sometimes it does work for no obvious reason

    2. The Mode Selector is touchy. Sometimes the right speaker does not work but when I fiddle with the Mode Selector, tap or turn it a bit, the speakers come back on again. This problem seems to get worth with time though...

    Is there an easy fix? Can anybody help me or has some advise for me? Thank you very much, By from Chad

    HI Chad,

    I have a Yamaha RX-V1500 amp and had the exact same fault. It was intermittent and would sometimes turn off straight away, or run fine for 15 minutes before turning off.

    I eventually took it into a Yamaha service centre where they replaced an amplifier for the front left channel. Unfortunately they didn't provide much feedback regarding the cause of the fault. They were able to explain that the receiver turns off as a self protective measure when ever it detects an internal fault. This is backed up by the trouble shooting guide in the back of the owner's manual. All up it cost $150 and took around a week.

    I haven't had any problems with the receiver since, and that was three years ago. I found the service centre by going to the Yamaha Australia website and clicking on the "service + support" tab at the top of the page.

    Good luck.

    Cheers, Evan.
    It's better to be thought of as a fool than to speak up and remove all doubt!

    As Tex79 says, its usually an output stage (power transistor) that packs up in older units. The amplifier has thermal protection/cutout in the event of a fault.

    I've replaced output transistors in a mates amplifier, but decent amps tend to use exotic and highly specified parts that are tricky to get hold of. Older units would be especially difficult in this regard.

    Service centre and replacement part is the best option.

    First off: You have two chances of getting your amp fixed for less than 100 Bucks - none and Buckley's.

    The fault, as others have stated probably lies in one of the output stages. My bet is that you have dry solder joints. A bitch to find and work on, in that model.

    The second fault, with the input selector switch, is due to Yamaha's cost-cutting, by not using decent, gold plated switches. The replacement switch from Yamaha (ca: $40.00) is gold plated (though it is the thinnest gold plating imaginable). For a good tech, it is not a big deal to replace. For a novice, it is a job fraught with risk. I'd charge around $180.00 for the switch replacement on it's own. The other fault is unknown.
