JVC TH-C5 Home Theater System (Subwoofer) Turns On Then Off; What's wrong?

arjun90 1,214 105 December 19, 2012 at 04:56 AM
When I turn my JVC TH-C5 Home Theater System On the Subwoofer Turns On Then Almost Instantly Turns Off; but the 5-disc DVD Play stays on. What's wrong? Do I need to change the fuse? I've plugged the subwoofer into various electrical outlets and also checked other wiring (speaker wires, etc.), but everything else not related to the subwoofer appears fine. Does the DVD Player have anything to do with this? (Since powering the Home theater system (DVD Player) is suppose to turn the power on the subwoofer). Without powering on the DVD player, the subwoofer will not turn on (which is normal). So, what do you all think? Please let me know, thank you.

more than likely the issue is impedance (OHMS) does the subwoofer have a rating and does your home theatre system have settings too low can cause an issue.

The JVC manual shows 3 OHMS which is pretty low

167 watts, min. RMS, driven into 3 ohms at 100Hz with no more than 10% total

Are you using the subwoofer that came with it was it a complete set, don't touch the fuse as you did not say it was blowing but the system as turning off as a way of protecting itself.

The receiver stays on when when subwoofer turns itself off. This is the subwoofer that came with the home theater system. I crosschecked with other outlets, but the same problem persisted. Are you saying its the power supply? Or something else? What should I do?

double check the speaker wire and otherwise it is the power supply more than likely there is a overload circuit that is tripping like a thermal overload switch once the condition goes away it works again since the woofer does it on any channel it is probably bad.

I feel so silly right now. I double checked all the wiring, and guess what? The AC cord was not ever connected to the wall outlet. I don't know what AC Cord I was plugging in this whole time, perhaps the AC cord which belonged to the old cable box. Darn, do I feel silly, right now. Thank you for your help; I greatly appreciate it! :-) I have a bit of house-cleaning to do now.
