Sub won't power up

Its all going to be proprietary to the jvc system. Unfortunatly you will only be able to use the speakers with another reciever.

check your internal wires inside subwoofer.b4 that try to connect to other instrument to make sure it not working.

sharazanct I had the same problem and posted here many months ago without any success. Just today, believe it or not, I decided i would replace the screws in the top cover and try it one last time. I don't know why, but it now works fine.???? My original problem was my receiver would light up and appeared to be working but I would get no sound out of the sub or speakers. I noticed at the time when I would first turn the receiver on the green indicator light on the front of the sub would light for a couple of seconds and then go out and would get no sound. Today the sub light lit and stayed on and I'm therefore able to hear sound as if everything was normal. I wish I knew exactly what I did, unfortunately I don't. If you have everything back together you might try unplugging the receiver and sub for some amount of time and come back and try it again. Good Luck!

the two issues are unrelated. a few turntables won't show life until the tonearm is moved over to the record area. at this point the motor should start turning wether it has a belt or not.

Try reseting the system. Instructions below.


DVD reset procedure for TH-A10

5. Then the display will change to : "TEST1 JC2".
6. Press "Enter" button on the remote, display will show "EEPROM"
7. Press "Power" to shut unit off.
8. Reset is finished

often your sub need to be change because of its malefunction.

Have the same unit and it does not have the capability to play anything other than commercialy produced CD's or DVD's i.e. no CD-R CD RW

Unplug the JVC and the subwoofer from that outlet. Then, plug them back to a different outlet (where power is constant and not interupted by any switch.) Hope this helps

Check your cable that runs between the main unit and sub for bent pins. If they look fine there may be a short in the sub itself that is causing it to go in to shutdown.

The unit is going in to shutdown. My guess is a failed output. Service is going to be required.
