There is a very loud static electricity sound through the volume on my television. It is not coming through the cable. It doesn't stop and it gets louder if you turn the volume up.

Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.
A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?
Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.
comcast boxes can either have component cables or hdmi. sometimes the red and white cables come loose. check the cables on the TV and the box. If you are using hdmi, let me know and I'll walk you through some steps...
The sound chip may have gone in the stereo, especially if someone has had it on very loud they sometimes blow, otherwise you have 2 speaker wires touching each other, that way you only get static noise, insidee the door they sometimes come free and touch the body
Yes,loud static usually comes from bad isolation of sound signal path so it's probably a frayed cable or a loose jack. Or if you're unlucky some parts inside have failed.
I have had the identical problem from the beginning. It happens in humid weather. Unplug the set while it's on, wait a second, plug it back in, and turn it on. Sound should be fine.
The static noise may be a defect. If your laptop is still under warrent, contact dell for a warrenty replacement. I had the same problem with my inspirion. Sigmatel
shut down all electrical sets around and check if the static goen the problem will be in electrical sets and you have to check it one by one.if it is not solved check your cables for any bad connector -open circuit- short circuit(try with a couple of new cables).-apply a contact cleaner in all sockets and move jack in and out in all sockets(with no power on)
You can possibly diagnose the problem by trying a different speaker,it does not have to be the same shape as the original but it has to have the same amount of resistance (ohms),radio shack might have one that you can try or one from a broken radio ,if you use one with different value it might not sound as loud but we are trying to see if you hear the static or is gone.You need to unplug the unit from the wall,remove the back cover and locate the speaker,disconect the wires and reconect the one to try then plug the set and turn it on,the antenna will need to be reconected too.Is the most simple test you can do without getting in too deep.Let Us know how it goes by a way of a new question or if you need more information.
