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.

Hello, it,s very possible that it,s circuit protector built in to the sub (if it,s a self powered sub) gets to the point of overload and shuts off as a protection so that the speaker won,t get damaged and also so the internal amp tha,t pushing the speaker sound is also protected since theese amps all have heat buildup, their are two types of subwoofers ,They are the powered ones and the ones that are powered bt the surround amp ,The ones powered by the stereo surround amp/tuner tend to throw out less power to the sub and the ones that have internal power are mostly higher powered , Another thing you might want to check is your polarity to the speakers and also the omage , Most home theater system speakers are 8 ohm,s but their are speakers and amps that can be changed to 6 ohm,s ..so you might want to check the speaker rating also . Well hopefully you can use theese different methods to at least troubleshoot and discount the thing,s that are not the issues , Good luck and hope theese sugestions might help you , Sincerely Glenn

A connectivity check could provide the solution, notice any wrong wire connections on device or any other devices requiring interconnection. The woofer would perform properly when the connections that provide current for woofing are approapiate

important notes
1. Trace the connection from Recorder or sound output to the woofer device
2. The wiring connections should be sound and video ouput into sound and video output into woofer.
3. The connections if any problems would be located at the stereo recorder or device producing the spund and video. Check the connections of wires on the recorder device ensuring rewiriing
4. finally, adjust the equalisers if any the buttoms could have been disbled by master switch hindering full blaster boost sound.

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)
