Re: No audio at all and buzz in the speaker output.

Sounds like an input device switch is frozen or locked up?? try unplugging for overnight and taking any clock or battys out of the unit as well.

Protect mode jvc


The protect mode is activated when it senses a short in the audio outputs in the stereo. Turn volume down, power off, and remove speaker wires from the back, next power on, if the protect comes on the audio output ic is shorted, if on the other hand it runs, check speaker wires for shorts and then hook up one at a time to find the fault including the speaker.

My stereo won't work. Whenever I try to turn it on, it always turns off saying "protect." How can I fix this?


The protect has come on because it senses an output load problem, Turn the unit off, unhook the speakers and wires from the stereo, now turn the unit on and turn the volume down as far as it will go, this should reset the processor ic, if the word protect stays off you have a short in the wiring or bad speaker. If the protect comes back on with everything unhooked the problem is in the audio output ic pack in the stereo and will require a technician to remedy.

Laptop doesn't see Teca cassette deck


I'm not sure why you are unable to see the usb device, but I am surprised you are using a speaker level output to connect to it and not a line level, which is a much smaller signal. I've never heard of an RCA to USB adapter, but I like the idea if it works. I normaly just go into the line input jack on the back when using a desktop computer. Does your laptop have a line input jack? Good luck.

Sound went out


If your head phone is connected to your system there will be no out put to the speakers. Please remove the head phone and try. If this does not solve your problem then there is a possibility of defective audio output IC.

I had the same problem with mine and the fix for it was to replace the Q401 transistor on the main board. Used a NTE382
replacement and it has worked fine.

Rear Speaker problems


The delay is normal as it's designed to create a spacious large room sound. The buzz however, is not. It sounds like the power supply is bleeding into the amp and should be serviced.

Opening up Speakers


i it wood or plastic? if you cant easily pry the 'screen' in front off and there are no screws, your best bet is just to find a new speaker box to put new speakers in... only way to open it is to tear it apart, unfortunatly.. if you do decide to open it, CAREFULLY cut the screen off with a razor or exacto knife, once inside you'll know better what your dwaling wiht...good luck
