Question about JVC TH-M505 System

1 Answer

SUBWOOFER WON'T POWER ON (Grounding out???)

I have a JVC TH-M505 system. I am using all the factory speakers as well as the factory subwoofer (which runs all of the speakers) I was redoing my floors and I had to put the subwoofer on the fireplace until I finished where the subwoofer was - I put the subwoofer back down on the floor, and now when I turn on the unit, the Subwoofer light comes on for about a second or so and then turns off. I suspect that maybe it is grounding out or something but don't know how to resolve it. I have disconnected, and reconnected the speakers, changed the outlet I had the subwoofer plugged into and nothing changes. ANy help or suggestions would be greatly appreciated.

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.

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.

JVC Home Theater System M505 The subwoofer will not come on and it appears that the system (speakers) will not work at all until it runs thru the subwoofer system.


Wiggle on the long round cable connected to the Sub woofer. If the SW turns on, open it and solder the connector or change the connector

There are very few uses for the subwoofer. Try it on FM if you get audio the woofer is working.
