Question about JVC TH-C50 System

1 Answer

Subwoofer Shutdown JVC TH-C50. Worked fine until few weeks ago when the subwoofer decided it wanted to shut down in the middle of anything that was playing. It is doing it more frequently now and we cannot figure out the issue. We have checked all of the cables, the power strip, everything. It starts again when you disconnect and reconnect the data cable (which connects the unit to the subwoofer) but it won't take long before it shuts off again. The DVD player itself is fine. All of the speakers play great, and all the setting are set to the manual specs. Has this occurred to anyone else, and does anyone have any idea as to why this is happening? Thanks for your responses.

Re: Subwoofer Shutdown

Whay don't you take a look at your data cable and jack contacts to see if any of them are bent or misplaced. Terry

I have a Th-C50 home theater and lost my subwoofer system cord, can I use a regular s-cord to make that connection? or is it useless with out the cord?? Please help!


Yes you can use any 2-core cable to carry the bass signal to the subwoofer. As the bass speaker cone is the largest cone in your speaker set I would recommend a good quality cable of decent gauge (thickness) to carry the bass signal.

You just need to make sure you have the right connectors for the amp and sub and make sure you connect positive to positive and negative to negative.

Hope this helps,

Subwoofer powers on for about 4 seconds and then shutsdown

I don't know if you were able to get the problem fixed, but I had the same sort of problem where it worked and then all of a sudden it stopped working right in the middle of a movie.
I took it to a repair shop and he found that it was the power supply... a $4.00 part.

Subwoofer shuts down

Check the connection in the back of the sub,where your wire plugs in from the DVD unit, the connector is loose in the unit itself. Had mine replaced and is doing the same thing again

SUBWOOFER WON'T POWER ON (Grounding out???)

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.

Subwoofer not powering up

I could either be the sub or the main unit. The main unit actually sends a signal to the sub to turn it on so if that circuit is bad in the main unit the sub is never going to come on. I've also seen bad cables (You'd be amazed at how stubborn people can be when din connectors don't cooperate).

Subwoofer JVC TH-M606

What system are you using it with, how do you have it connected, when you say the system does not work as a result, does it mean that the system does not power up, or no sound?
