Question about Audio Players & Recorders
My yamaha avx 700 amp will just switch itself off quite randomly and without warning. Sometimes will work fine for hours and then just suddenly switch off. Other times it switches off immediately i switch it on. This is obviously a very annoying problem and one i would love to find a solution to to as it is driving me mad! Any advice on this would be greatly appreciated. Thanks.
I have 2 of the same receivers. One works perfect and the other had the same problem as you describe. The faulty one I brought to work to use. Since I wasn't planning on recording anything I desoldered both swithces and swapped them. The REC OUT switch is a 6 pos SW, and the INPUT is only a 5 pos SW, but it works. Now my sound doesn't cut out any more and I have a receiver for work.

Try hard reset, check the manual how to set things back to factory settings. Ensure all cables are connected properly, all + on + and all - on - (don't forget to check the speakerterminals!). Some equipment do into auto-protect mode when a + and - are incorrectly connected.

The AMP-ERR message in many Pioneer Receivers is caused by some DC in the output. The microprocessor then issues the warning and shuts the unit off. It is definitely not a relay switch. It could be the amplifier power pack, i.e. PAC011A or similar that is faulty or something else. Not easy to repair for the non- experienced DIY.
