Question about Panasonic CT-35SF23 35" TV

Open Question

Subwoofer buzzing I have a Sony STR D560Z and when I bought this 12 years ago, I didn't have a subwoofer to plug in. Everything worked fine. Two years later, I upgraded my surround sound and added the rear, center channels, and of course a Cerwin Vega 12 inch powered subwoofer. From the beginning, the sub would buzz using the cord provided from CV. So instead of using the cord, I just ran the right and left speakers through the sub and ran the right and left front speakers from the sub and everything was hunky dory. When the CV Sub fried its card, I bought a lower priced 8 inch subwoofer from JVC. It has no other means of plugging it in except the cord provided. I plug it in and it buzzes too. I can fold the cord over itself and the buzzing stops and the sub works normally, but as soon as I release it, it starts buzzing again. The CV sub did this too so I know it is not subwoofer. I can plug the cord into any other audio out and it works without problem. Is there a cord provided by Sony that will prevent this or is the problem the receiver?

I have a Sony STR-DE597 FM/AM Receiver .It has audio out plug and i have a Jensen js650 100 watt Subwoofer. how can i hook them up? Thanks.


The Jensen JS650 does not accept line level input so you need to use the Front B speaker output from your Sony receiver and not the RCA subwoofer output. Even though your subwoofer is active, it does not support line level (RCA) signals.

Just connect the subwoofer as you would a pair of speakers. Once connected, you make sure the front panel speaker switch on the Sony is set to A+B so you get sound from your existing speakers (A) and subwoofer (B).

I hope that works for you.

Hi, having a problem with my Sony STR - DB790 amplifier. All my surround sound speakers work fine, but my subwoofer is not. The subwoofer has power and is connected using the co axial cable. The...


RCA cable. It's called RCA when carrying Line Level audio; Coaxial when carrying digital data.

Does the sub work when you run speaker setup? It's in the manual.

Can't get subwoofer working with sony model STR-DE845 receiver


read the manual

First, it must be a self-powered subwoofer, then you've got some settings to select in the receiver.

Buzzing sound from woofer when I plug in


If the woofer works fine when plugged into any other port, I would say that you have a connector on the receiver that has a loose connection or possibly a cold solder joint (poor or broken solder joint). RCA jacks can be stressed quite a lot especially if you use cables that have very tight connectors. The female RCA jack gets wiggled or twisted when trying to remove a cable and this causes solder joints to crack. I would have a look at that connector on the receiver..
