Check the fuse on the back panel or possibly inside the enclosure then if blown just replace with another one will cost about $1.00

I have a jvc seteup but reciever is broke.is there a way i can get a adapter to plug sub woofer with power amp into a a yamaha reciever?the plug that goes from sub woofer also powers other speakers, cable...


Here's a manual.

http://www.retrevo.com/support/JVC-TH-M505J-Home-Theater-Systems-manual/id/318dj491/t/2/

That cable not only carries audio but it also powers the sub and other channel amplifers. Even if we could supply the pin-outs for the channels I'm not sure what we could do to provide subwoofer power. We're talking about a major rework.

This is a highly proprietary design, meaning it's really not very adaptable to normal spec audio equipment.

There's a flat-fee repair service for the receiver ($99.95, free return shipping):

Maybe they could fix your receiver.

You COULD try to reach the manufacturer for other options.

The cord /with the pin on both ends that plug in the back of sub woofer & dvd player, i need the female ,plug that on the back of sub woofer


The part is called a Din connector. You may be able to find it at www.jvcservice.com You will probably need to use the sub-woofer or the system model #, it is not listed under th-c30

FYI replacing it is not very easy.

I just replaced the cord running from the sub to the dvd player. now my sub will not turn on


hi,
steps to trouble shoot for sub-woofer detection :
1. please check whether the cord is securely connected at both the ends.
2. check if there is transmission through the cord (there'll be a small static through the cord if there is transmission.)
3. reset the dvd-player to default audio-output and then choose the 5.1 sound system which is the correct setting for the th-c6.
4. also check the settings in the th-c6 whether it is in 5.1 mode(whether it includes the woofer-as it can also simple use the stereo speakers)
5. now check the sound output in all speakers by playing any original home-theatre system enabled dvd.

the system will work perfectly if the cord is in good condition, otherwise please replace the cord again, and this time check it at the store.
cheers

The subwoofer lites but no sound


Have you gone into the menu settings and adjusted the sub woofer volume, some factory settings are set @ zero.

Either the amp for the sub is bad, or the sub woofer speaker is bad. If you checked the fuses, you must know how to get the amp out of the sub woofer box (screws in the bottom of box and around the metal plate of the box). Take it out again and check the wires that go to the sub woofer. It is the red and white wires if I remember correctly. They come from the box and plug into the amp board with a white plastic connector. Or you can check the wires right at the speaker. The cover for the speaker comes off with about 4 phillips screws and then take the speaker out with the screw driver as well.Use an ohm meter and check the ohms on the speaker at those wires after you dis-connect them from the board. That woofer should measure between 3 and 6 ohms to still be good. If it measures less than 3 ohms or more than 6 ohms, it is probably bad and will need to be replaced.

Here is the JVC part number for that woofer.

CR250006-01

Be prepared, the cost is ridiculous. $110.16 at JVC's service site.

http://www.jvcservice.com/Service/JPartInq.asp?PgReq=DspDta&PrtNbr=CR250006-01

Or you could just find one that fits properly and use it instead. They are not the best woofer around and are very over-priced.

I hope this helps, if so a FixYa! rating would be very much appreciated. After all, it is the only reward we get for offering free help to people like yourself.

You need to take apart tthe sub woofer and check the connection to bass speaker for continuity. It sounds like an internal broken connection to speaker on sub woofer unit.
