Re: jvc rx 318 receiver

The problem you describe is common to JVC amps. This control has a motor mounted on the back of the circuit card that drives the volume control up or down using the remote control for this system. The looseness of the volume control cannot be repaired. The shaft has separated from the potentiometer. I don't know if JVC has this part any longer but it has to be replaced as a unit (volume control card).

Wow...I googed for that part and couldn't find it. I'd call JVC and ask to speak to a service technician. I don't think you could replace it with an old potentiometer. You need the one with the right resistance and size.

Iplugged my jvc rx-7010vbk 120v reciever into a 220v outlet, does it have a power supply fuse that would burn out or is the whole power supply shot, what parts do i need to fix it

more than likely the whole board is shot
fuses only control current flow and break when that is exceeded
It is the voltage that does the damage that same as when you put 12 volts through a 6 volt bulb

I turn the power on to my RX-318 and a few seconds later it sounds like something else is kicking on....then I dont hear any sound from my speakers. I dont know if theres a fuse blown, the amp is going out...

Sounds like the automatic circuit protection. Check to make sure you have good speakers and NO shorted wires to them. Too many spearkers conected to the outputs will cause the same problem.

I have a JVC RX 554v Receiver when it's turned on I have no sound their is a mute auto light that's lit in the window....Tried changing the speaker wires with no results...

From the remote control only: Press MUTING to turn off the sound through all speakers and headphones connected. "MUTE" appears on the display and the volume turns off. To restore the sound, press MUTING again. Turning MASTER VOLUME or pressing VOLUME +/- also restores the sound.
