Yamaha amp turns itself off immediately


I've got a fairly old Yamaha RX-V800RDS amp. Bought it in London whereit worked like a dream for years. It then sat in a box for two yearsdoing nothing.

I've now tried to hook it up in France. With nothingattached to the box, when I try to turn it on, straight after pressingthe on button a click is heard and the thing turns itself off.

Don't get anylights..nothing. Impedence switch on the back is fine. French elecricity is not the issue either.

Any ideas? Thanks

    Checked the internal fuse and that is fine. The thing actually turns on (so there is power) but then switches of after a second. It's as though the security feature is kicking straight in.

    Took it to a shop, plugged it in there and it worked. Took it to a friends house and back to mine and it doesn't work? Bizarre. The security protection is kicking in. Why would it do this in one place and not in another?

You could start with checking the internal fuses for failure.Remember to unlug at the wall before touching any internals, replacing a blown fuse with power up and holding onto a stell chasis can be very unpleasant!! Check back with me here to go from there :)

    I have the same pb !
    Iv'e bought my RX-V800RDS 10 years ago. Work very fine.
    But one week ago I've got the same pb : : when I turn on, tha amp automatically turns off.
    But if I just unplug from the wall, wait a couple of hours, then plug in the wall. Then it's OK !
    I stop it, try to restart : impossible.
    So I don't think it comes from the fuse, since it's working somtimes. Any other ideas to solve this problem ?

I have Yamaha RX-V800RDS

After sitting that long the capacitors in the power supply can dry out and become inoperable. The first thing to check is to see if the power supply inside the stereo is working.

My Yamaha receiver RX V463 is immediately turning itself off after I try and turn it on? (both with remote and on the receiver itself)

Power it On without speakers connected.

If it powers up, reconnect speakers one at a time to find the cause.

If the problem persist even without speakers connected,

these unit needs servicing.

if you have any more questions let us know.

Your receiver probably went into protect mode because you were overloading the output stage with concert blast. In some units, protection consists of fuses that blow; in others protection is provided by thermal shutdown devices.

Yamaha RX V490 Turning itself Off

The amp is in protect mode which means that the output section has a problem. With nothing connected, there are defective parts inside the unit. This type of problem is not likely to have been caused by any shipping damage. I would guess that the output transistors are shorted.

Yamaha Receiver RX-V630 not working (resets itself immediately)

This maybe an easy one. Have you unhooked all the wires going in to the stereo. "SP wires" means you have wires to the speakers are touching and the stereo is shutting down to avoid overloading. Hope this helps...

Yahama receiver Rx-630 not working

The problem might be caused by two major circumstances. 1)Touching wires 2)Overheating. I suggest you unplug all wires connected to the amp then turn on the amp. If it gets turned on then we know that the problem is that you have touching wires. If there is a short circuit somewhere, get rid of it. The ventilation is another important issue that you have to pay attention. It simply causes overheating.

RX-V1500- front panel lights not working

The display on an amp has two components.
A small Lamp (light bulb)
A LCD display with a color filter.
Normally when the display goes out the problem is with the lamp
The lamp on my RXV 870 died after about 9 years of use.
I called Yamaha and was able to by a replacement.
The lamp is an odd voltage 14.5 if I recall.

Looking at the receipt i should have bought 3 for the cost of shipping. It cost about 10.00 cnd,
