JVC TH-M303 Home Theater System: No sound out of subwoofer despite the green light

Sat, 09 Mar 2024 19:20:15 -0700

I recently had to unplug my sub due to a move and when I went to connect it back it isn't working. The green light is lit, but there isn't any sound coming from it. The floor speaker have sound output, but the sub doesn't. It also makes this loud cracking and popping noise if I touch the connection cable while on. If the noise is too loud the sub will automatically shut off and then turn back on, but still no sound. Could there be an issue with the connector plug? I did notice a pin or two were bent and I straightened them back. I've had this system since 2005 and it's never given me any issues until now. Thanks for any help you're able to offer.

JVC TH A35: Only the sub and center speaker working?

Mon, 30 Sep 2024 12:52:32 -0700

I have this home cinema with only the subwoofer and the central speaker working. The unit boots up with blue light, so no protection mode nor short detected. All fonctions are available (radio, cd, aux etc...).
I have the schematic of it but no idea what to look at and how. Seems that the sub and center speaker are both connected to the same relay but I don't get how the 3 other have failed as they are all powered from the same supply?

The cable for the Connection of the DVD Player and the Subwoofer (audio Connection) type S-Video has been damaged.

Because of that, the entire Home Cinema system has been disabled

Is it available somewhere, even abroad?

JVC TH-M303 Home Theater System: Subwoofer won’t produce any sound

Wed, 24 Jan 2024 08:34:51 -0700

I got this system a few months ago in very good condition because it was hardly ever used and it’s been working perfect for me until a few weeks ago. One night i was watching TV and the subwoofer shut off on its own which meant all the other speakers shut off as well. I shut the head unit off and back on a few times which would turn the subwoofer and all the speakers back on for a second and it did the same thing. On my last attempt when i powered everything back on the subwoofer made a loud “pshhh” sound as if something popped and was relieving pressure. After that I shut everything off and unplugged everything. I did notice that the back of the subwoofer was extremely hot. maybe it was overheating? Everything sat for about a week or two unplugged and i decided to hook it back up to see if it worked and everything works and the subwoofer stays on and passes the sound to all the other speakers but does not produce any sound its self. I took the speaker out of the subwoofer and tested it and it works so i don’t know what to do from here. It seems like the subwoofer speaker isn’t getting any power. I would like to keep this system because all the new options don’t have the same features like this one does.
