Unplug the power cord of the receiver box for 10 seconds and then plug it back.in job done..

Are you sure the message is coming from the TV or could it be comming from a component you have connected to the TV?

Sounds like firmware corrupted. A firmware update might be necessary. Contract the authorized service center for Vizio.

We regret to inform you Panasonic TV's do not use any errors similar to Debug. We recommend you contact the source provider that the TV is connected to.

If your tv is under warranty, just send it to them for fix, otherwise you need to get into the "debug" or "maintanence" menu of the tv. Google the model number of the tv and things like "debug menu", "hidden menu" or "change horizontal scanning".

Your horizontal scanning option is set too far to the right of left.

what IE are you using?
the debug will appear when you using IE6. the reason is that most of th web site have activex. IE6 can't handle it. you need to install IE7 sp1.

When I got my new LCD big screen, it had a black line across the entire width. It looked like the screen was pinched.

They claim that it can be repaired but that repair costs as much as a new tv.

My tv was replaced. Hopefully your warranty is still in place to get the unit replaced.

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock.
