Re: Yamaha amp turns itself off immediately
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 :)

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.
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.
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...
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.
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,
