Woofer is humming

Usually a faulty cable or blown speaker will cause a humming. If it is a constant humming I would surmise a faulty cable. On the other hand, if the humming comes and goes I would guess a faulty speaker.

Subwoofer is hummig what is this noise

Hum is a constant low-frequency buzz, usually at about 60 Hz or 120 Hz, which results from voltage differences between true "ground" (what you'd get shoving a copper pipe into the ground) and the electrical "ground" of your receiver's chassis When this voltage differential exists, it's called a "ground loop," and the hum it produces is darned annoying. You'll hear the hum mainly from the subwoofer because it's a low-frequency noise, you will need a ground loop insulator they are about $20 at any electronic store

Vizio remote control won't work with tv..

Just unplug the TV from the power outlet and hold down the power button on the side of the TV for 15 seconds. Doing this drains residual power and can clear up odd issues. Then plug the TV back in and power it on. Test the remote again to see if it's working.Mar 10, 2015

My Vizio m55-d0 TV keeps flickering between completely red, blue, white,black and green screens.

Try to turn the TV off and on by removing the power plug. Leave the plug out for at least one hour and then try again.

I hooked up a vizio 5.1 surround sound system to my 55" roku ready tv everthing worked but the satellite speakers what did i do wrong

Are you sure the Sub has power and is working? If the sub isn't working, try re-linking it with the sound bar.

Can the vizio sub woofer be connected to a phone without sound bar

I would have thought that without the other speakers all you would get is just a lot of bass, the phones own speakers would not really be a match for the sub. Assuming the phone has a sub-woofer socket!

Hello, I have an LG42cs560 w/o audio output. I'd like to attach a Vizio soundbar. Is there a work around for this?

Unfortunately no. There must be a source for the audio. If there is no headphone jack or Audio output of some sort there is no way to make the sound bar work with the audio in the TV.
