Question about JVC TH-C5 System

Open Question

No Power to Subwoofer (SP-PWC5)

One day the light went out on the subwoofer and never came back on. We have electrical storms from time to time so I figured I blew a fuse. I took off the back plate and tested all 3 fuses and they tested fine. I then read that a bad cable from the center unit to the sub may cause the problem so I ordered a new cable and it still didn't come on. I guess I may have a blown transformer because I don't get 12v DC on the cable from the transformer back to the board (not sure if I tested it right since it has 2 reds 2 blues and a black). Any ideas?

    no power to subwoofer

    If you ohm out the primary side of the ower transformer you will notice you have an open. This is do to the internal 5a fuse blowing. There is nothing you can do other than relce the QQT0482-001 transformer if you can find one.

    While rearanging the placement of my th c5 powered sub by scooting it across the carpet, I recall a sudden and loud pop and saw a spark like flash for an instant. Now their is no power to the woofer and no green light, however, the center channel works; but no sound is possible.



    If this was caused by a power surge, how can I fix?



    Also, I found three fuses inside the sub compartment that looked good but was wandering a good rule of thumb when visually inspecting the fuses, and how can I see whether they are still good?

    Yes. Just bought a new DinPin wire, and when I turn the reciever on the sub clicks as if attempting to turn on, then clicks again as if turning off. Light on sub never turns on....is this a problem with a fuse in the sub or reciever, and if so, should I just buy a new fuse or a whole new sub/reciever??? So many questions, so little time.

SOURCE: 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).

It is possible that the power supply, and or the internal amplifier has some components that have failed. The unit will have to be serviced.

Get in touch with JVC to find out if your unit is still under warranty, and to find out who is their authorised service rep for your area.

SOURCE: sub won't stay powered up

well if your getting sound out of your surround speakers then the sub is busted, if your getting no sound at all then your speaker input's are either bad or out... i would test the speaker inputs...

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)

The blue light still continues to flash


Push in and hold the switch on the back of the subwoofer until the light starts blinking fast. Then, with the soundbar power turned off, hold the mute button on the remote. "ID SET" should show up on the display. Then turn on the soundbar, and the subwoofer should link to it.

Can i put an extra sub woofer on my lg da3525 via the woofer out socket and what plug do i require to do this


Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

Power issues: will not turn off or function


Unplug all of the speakers and power on.Its possible that one of the speakers is causing the protection circuit to activate.If powered on and subwoofer works start reconnecting one speaker at a time( after powered off) and retest each time.One Speaker may be bad.Its also possible the output ic is failing under a speaker load.There are no fuses related to this issue.If its not a speaker problem then the subwoofer will need to be serviced.

MOst of the time it is the jack that the cable plugs into that has the problem. .
Also the jack is not broken but HAS broken the solder connection TO the jack.
If you know someone who can safely take it apart and solder, let them try.
