There is a chance that your wiring is producing this problem. Manufacturers don't always make equipment that is compatible with each other. The biggest problem's are "ground loops". Radio Shack has a non-electrical device that separates the common ground from all equipment. You basically connect it between your amp out's and in's - cables included. It is possible that other manufactures also make and sell this device too. It's main "Google" name would most likely be - "Ground Loop Isolators". If you are using the actually speaker outputs into your subwoofer amp input(s), check your polarity wiring again. Good luck with your system - it sounds like it'll rock when it's all setup correctly.

The subwoofer output on my Kenwood VR-606 has suddenly stopped working. I have tried the "setup" several times, turning the subwoofer off and back on. Also, when I first power up the system, it emits a low...


It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps.
Cheers, Don.

My center speaker is humming after i turn the tv on.


If you center speaker is humming, you when you turn on your TV, you may have the audio signal over amplified and the hum may be coming from your TV itself. Try moving the speaker further away from the TV or the amp further from the TV and see if it solves the problem.

Hi, what causes hums from speaker is when there is no ground shield from either the power supply or from the cable you plugged into the socket from the power supply.

So you will need to check that out and replace untrusted cables for connection..

If after doing this troubleshooting exercise, you will now need to test the speaker with another set to be sure the humming sound is not coming from there.

I guess that will Do.

Have a nice day...

Sorry this is not a solution.

I am having virtually the same problem and I wanted to find out if you managed to fix the issue?

It seems to be my LCD causing the static noise (even when it is powered down). The static noise goes away when I physically unplug the TV or disconnect the HDMI cable to the amp.

Speakers work only on DVD


You might have connected your TV/Stereo Receiver up to the wrong audio outputs of the DVD player. Make sure you are coming out of the FRONT left/right audio outputs and not the CENTER?REAR left/right audio outputs.

Hum from speakers


I suspect an open ground or bad cnnection in your hdmi cable to the amp from the sat.A hum is very indicative of that situation

Sound not coming from left side surround sound speaker or my right side front speaker


it is highly likely that you're TV is outputting mono sound, hence the left channel only. check your physical connections to the TV and the balance / channel volume on the television as well.
