Volumne control not working

Avoid some channels because they are the ones who contain this problem

F12 increases volume. You may need to raise the volume on the browser before you go full-screen.

nothing works but the power . it has a great picture but you cannot control the volumn or change channels. what can be done to fix it. ...

I came across this web site while researching similar issues on my radio:

If your volume controls are not working you may need to reinstall or update your drivers. These drivers are available via the dell website just use this link.

I have to turn my volumn to 100 to hear it and the tv is 1 month old.

Open the speaker where the volume control is located then check it if there are lose connections. You can also clean the variable resistor or the volume control with a contact cleaner solution or oil... ^_^

Yes, the sound stays constant, a few commercials like Billy May is louder but he is louder than anything else in the world.

Very pleased with the volumn

You've got a fried output transistor or one of the small preamp transistors that feed the output on the left channel. Both of these transistors are after the volumn control so it would have no effect on the buzz. Good luck.
