The overload light comes on and then amplifier clicks off. Was working perfectly. Must have pressed wrong button?
Might be a shorted speaker wire or speaker ..unplug speakers and try again
SOURCE: OVERLOAD
Turn the unit all the way down. Now, before you try to power up again, make Absolutely Certain that there are no shorts or damaged wiring going to the speakers. Still no go? Then try to power up with no wiring attached. Good? Now just the wiring, no speakers. Make Sure that there are no wires touching! Then try speakers. If there is a problem, you'll find it .....accordianman
SOURCE: Receiver won't turn on. All I got is the flashing light.
Try pushing these buttons at the same timwe for a few seconds:
Advanced Surround + Enter..
'Advaned Surround' will be found in the front panel and 'Return' near the multi-jog dial.

The stand-by light is supposed to go off when you power on the receiver. You should get the display light and you should have power on.
SOURCE: Right light comes on- but then shuts off trying to get to turn on
First, check your fuse, it really could be that simple. Check it with the Ohms setting on your DMM, do not bother with continuity. If it is under 1 the fuse is fine.
It actually sounds like a short in the amp circuit. Inspect the amplifier where it connects to the heat sink. Check for signs of oxidation or any contaminant that may cause a short in the amplifier. Ensure there is ample thermal grease between the amplifier and the heat sink. You may wish to reflow the 22 pin connection on the board. I would recommend desoldering the whole component if you can, cleaning and testing it, and resoldering to the board with fresh lead free solder and no clean flux.
If the amp is blown you can replace it for around $70 USD.
Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
