Question about JVC RX-668V Receiver
Try first to disconnect all of your speaker wires and turn back on this receiver. If the problem persists, you will need to take the unit into a shop and have the output circuits checked out, as these are all solid state parts that are soldered into the printed circuit boards and there are no user replaceable parts inside this receiver. Good Luck

SOURCE: my jvc rx-6010v is OVERLOADING?
The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. (JVC - and others - say SIX ohms, but 8 is the "standard" you should use.) Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: The internal overload protection system you mention is designed to help prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized JVC service center must do this. Note, though, that if you have attempted to "cheat" the system several times, damage CAN be done that requires servicing.] But, before you take the unit in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!

SOURCE: it says overload
All the speakers connected right?
ANy speaker fuses not accounted for?
If you moved , someone may have dropped it or bonked it enough to crack a printed circuit board. That would make things unpleasant.
It's fairly easy to fix a cracked PCB if you know what to look for.

SOURCE: overload flashs
there will be 6 amp circuit in your receiver. you can't unplug them one by one. with a multi-meter you may be able to find the shorted channel. (most JVC receivers use discrete circuits instead of an output IC) Check for shorted transistors attached to the heat sink. You will possibly find some open resistors also. Generally this is a job for a pro.
