Yamaha avx 700 switching itself off

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.

SOURCE: Yamaha Receiver R-700 Input & Recout switches cut out!

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.

Try to provide better cooling for the projector.

1. Check the ventillation for the hall
2. Check the cooling air circulation fan
3. See whether anything is blocking the air supply

Verify loose connection of power cable.

2. Check for damage of power cable

See whether any message is displayed before switching off

2. Try getting help on the error ID

I hope, this solves your problem

T104r timer manual switch not working, clock runs fine, on and off trippers work

The contacts inside the time clock have most likely warn out. If it is coming on randomly it is not making good contact and will create arcing, which is dangerous. Call an electrician, they may be able to replace just the internals.

1999 grand Marquis will quit starting randomly without any cranking either. It will start if the car and steering wheel is shaken vigorously while turning the key. Why?

I would guess that one of the wires to the ignition switch or the switch itself is intermittent. Replacing ignition switch will likely fix it.

Why does my Disco 2 R990 radio switches itself on and off at random

Is there a laptop near by? Some (most older) laptops, can send out infra red codes. Used for infra red communication with hardware. I once was shocked when my lights went on and of without any cause. Till I found my very old laptop did so, when I used certain buttons.
Perhaps even another remote control is sometimes giving the right code, just to switch on?

My dvd wont switch on

Make sure all your wires are plugged in even your HDMI to HDMI because HDMI controls itself from the TV sometimes and will let it turn on without that HDMI cable being plugged in

Fan just quit working one day. Nothing happens when I turn the light switches on and off.

Is it powered thru a light switch? Sometimes those do just quit. You can remove the old switch & replace it. Go to Lowe's/Home Depot, the switch itself is fairly inexpensive (probably less than $5). Remember to turn off the breaker to that room/switch before you do anything. The installation itself is simple - just wire + to + and ground it. Did you notice any kind of noise/smell before it stopped working? If the motor is burnt out - just replace the whole fan (unless you feel like tinkering with breaking it down & finding a replacement motor). Sometimes the lite switch on the fan itself will go out - parts for that can be found at about any larger hardware store, but sometimes that's not an easy repair (depends on what type of lite kit is on the fan). However, if that were the problem -it would not cause the blades not to turn, it would only keep the lights from coming on. Try replacing the light switch that turns the fan on/off first (the one on the wall, not on the fan itself) - hopefully that'll solve it for you. Good Luck.

Randomly switching off and coming back on by itself.

power supply board may be failing or the power button may be sticking. If it is a Samsung, it is the power supply.
