Thank you for your quick response... guess I'll start from the beginning.... The set was on while I was in another room, I noticed the sound had stopped, I went back into the room and the picture was on, I tried to raise the volume and it showed on the screen but no sound emitted. I tried other channels and result was the same. The mute button wasn't on. I tried turning off and on, and the neither picture or sound returned, makes no sound and nothing appears on the screen. Purchased in Oct 2007. Have been thru troubleshooting with both cable and VIZIO over the phone.
I think I have a voltage meter, but would I be working with live electricity?
ok. I was looking for the tool, true, not comfortable with it. The Vizio is kind of big, so how do I find a qualified tech in the Reno NV area that might make a housecall?
