How to trobleshoot and fix a JVC stereo-hardware?
Unplug the unit from AC power for 30 minutes, and disconnect all of the speakers and other associated equipment. Upon plugging back in, press and hold the power button at the same time for 5-10 seconds to force a hard reset. JVC Audio | Answered on Feb 14, 2020 1 Answer.
Why is my class a receiver getting so hot?
Class A receivers such as this are designed to operate in a very inefficient portion of the amplifier performance curve, and then naturally generate lots of heat. Your unit is heating to the point that the amplifier is operating in another region of its performance curve, causing the distortion.
Why is my krv-7070 receiver getting so hot?
My KRV-7070 shuts down when it gets too hot. It is either off or on, so your problem is interesting. You didn’t mention whether the receiver’s built-in fan was working. They can fail, as can the circuitry that turns them on. Also, check that the 8 ohm/4 ohm switch is in the proper position.

What causes JVC amp to go into overload?
The 4 ohm speakers are causing the amp to go into and display OVERLOAD at higher volumes. Page 5 of your manual is poorly written, but clearly implies 8 ohms is the minimum impedeance required for speakers connected to this JVC amp.
