It seems like the device is in a some sort of protect mode, this happens when the power amp ic is in short or it could be cause by a bad regulator in the power supply.It seems like the device is in a some sort of protect mode, this happens when the power amp ic is in short or it could be cause by a bad regulator in the power supply.

I'd troubleshoot first, even though you've already tried the headphones (good thinking). Get a battery (AA battery works) and put the black and red wires on opposite sides to see if the speakers are working. Is there a menu of settings on the jvc, and is it set to 5.1? Just trying to help...
the problem is probably a bad power transformer that will need to be replaced the best way is to contact JVC and they will be able to help you more. it may be easier to purchase a new reciever.
Does the receiver work OK? These are probably electromechanical switches (called relays) which yamaha uses a lot. They use electricity to connect/disconnect something by magnetic force and this causes the "clicks". It is used for example to connect the speakers to the output of apmlifier only after it has finished initializing to protect both the amp and the speakers. When I turn on my RX-V465 I hear at least one click, it is probably connecting power to the amp. When turning it on with Radio button on remote I hear 3 clicks over 2-3 seconds. So these clicks are normal and nothing to worry about. They occur also when you switch to the PURE DIRECT mode.
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.
I replaced R916 with a 10 ohm wire wound resister and that fixed the problem on the unit I have. That resister is in serise with R 915 so they should be close in value. Both were marked 8 ohms but tested about 11 ohms on R915 and the bad one tested very high (over 1 meg) so I replaced it. When I first put it back together it didn't work but I noticed that the ground screw at EP901 was not retighted so be sure that all ground screws are tight and all conections are redone before testing with the power cord.
