    i have the same promblem i have even switched jacks around the house and still nothing so i opened it up and i think i could be the fuses inside because when i turn on the dvd i hear a clicking sound inside the subwoofer but it does not turn on so it gets power but it loses it somewhere because it does not turn at all could it be the fuses ?

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.

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!


Hi,

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,

Chris

No power. Will not come on with remote or manually. Switched power cords with no luck. Green light on subwoofer off as well.


On the bottom board is an electrolytic capacitor (C975) that might have failed. The top will be convex (bulged out). Since this is in the power supply, the unit will not work. Also: Check resistor R4843 and diode D4709 for charring on the board (indicates extreme heat). I have been trying to find the value of that resistor and so far no luck. Replacing the cap brought the set to life, but there is still a problem since the sound will cut off momentarily randomly. The receiver unit is at fault, not the sub unit. So I could use some help as well!! Good luck.

SP-PWM505 subwoofer does not stay on


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)
