    I actually sent my to the company under warranty to get it fixed. The stupid people couldn't even figure it out themselves and they work for JVC. I am no longer under warranty and now they say I have to pay for a fix. I think they did that on purpose.

Well i had exactly the same problem, my sub turned off right away when i turned the whole thing on. Well i opened the subwoofer and was trying to find out something unusual, i took out, i believe, internal amp, well, whatever that thing is, under the lid. Which one is screwed with 6 copper screws, so you unscrew those screws, lift that lid and that whole board comes out. On that board i find something like burn around one of the parts.

you can see it in the pick, the part q2902, then i contacted JVC. At the beginning they said i need to take the whole thing to service center and so on. But later i made them to tell me what kind of part that is, so here :http://www.jvcservice.com/store/ProductDetail.asp?Part=KTC3199/GL/-T
bought soldering gun in home depot for $15, returned after i was done. And that is it, just have to replace it, but total cost only $12 ($5 part +$7 shipping)

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.

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.

Why can't we get the sound to work by hooking the DVD player directly to the tv?


The JVC system is designed to output audio only via the speaker terminals at the rear of the system. There is NO provision to send audio directly to the TV from the system.

Page 14 of the manual (link provided below - free to download) details the connections available to a TV. These connections are limited to three types of connections: 1) "Video" for standard TVs which is "good" 2) "S-Video" for TVs that have an S-Video input jack which is "better" (both #1 and #2 are considered "composite" types).

The third type is called "Component" which is used for TV's that are capable of "progressive scan" video input which is "best" for the system. Notice that the jacks on the DVD player are labeled "Y", "Pb" and "Pr", not "Video", "Left" and "Right". This type video signal requires the use of three cables - they do not send audio as you may be used to see on all but the newer TVs. TVs capable of displaying "progressive scan" video have a better looking picture when using these jacks. Incorrectly connecting the video from the DVD to the TV audio inputs (Left & Right) will likely result in noise or hiss from the TV speaker.

To recap - audio can only be played through the JVC system's speakers. Use the highest quality video jacks that BOTH your TV and the DVD player supports.

I hope this was Very Helpful and enjoy your DVD and TV!

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.

JVC TH-M505 powers off right away


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

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).
