JVC surround nouns system repair cross-question.? I have a reasonably new JVC surround nouns system
I have a reasonably new JVC surround nouns system that is on the fritz. The manager unit will work fine, the problem is within the sub-woofer/amp. When I turn the system on, the amp/sub turns on for a second or so and turns off. I checked adjectives the fuses and such, but all looks fine. Does anyone enjoy any ideas what I can do to fix it except shipping it off for service? The amp weigh a ton, so shipping and repair would cost as much as a new system. Thanks!
Answers: Disconnect the vanished and right channel cable and see if the same item happens. If it still shuts rotten with nil connected to it, then the trouble lies inside the sub.
If you are comfortable next to a volt/ohm meter, you can purchase a service manual from JVC for the amplifier inside the subwoofer and possibly troubleshoot it yourself. It's a pretty simple circuit so the instruction manual should be cheap. Check first for a shorted output device since they are always lower than a lot of strain within a subwoofer.
If you don't already have a meter, and choose to walk buy one, it's helpful if it can tryout for diode effect.
Another route would be to check with a local repair shop. They will charge you, but it might be cheaper than paying the shipping.
Best of luck!
