Screen zipped down to dot of light in center and went blank. No audio either

The TV was on and quite suddenly the picture zipped down to a point of light in the center and went black. No audio at the same time. Unplugged for a period of time and plugged back in. Power light comes on, no picture or audio.

My 2006 manufactured Viore flat screen plasma tv suddenly went blank. Still have sound. Please help!

Read the following:

Different TV, but most likely same problem and, in fact, quite possibly literally the same boards, so maybe practically the same TV.
Can't be sure since you haven't posted the model of your Viore.

If you have specific questions, please always include the model number in the question...the model is on a sticker at the back of the TV, right after or below the words "MODEL:" :-)

Tv doesn't work

If your projection went down to a single dot in the center then you are most likely at the minimum replacing all three projection tubes due to that dot. It will leave a permanent mark in the center of each CRT and not repairable. The cost on that old set aren't worth it.
