Your tv has it's lcd screen backlit by some special neon tubes, called CCFL tubes. In your case the connection to one of them is bad so it's getting its power only when the heat from the other tubes and components expands the metal from the pins in the connectors.
To fix it you will have to take the back cover of the tv off , take off the tube shrouds and reset the tube in its connectors - eventually pinch them a little with pliers before reinserting it.

    Have you seen those economic bulb that you should use instead of the regular ones? They are exactly that - CCFL tubes. Just that in your tv they are straight and hidden in the frame of the tv , right on the side of the lcd panel - they are covered in reflective shrouds. You can't miss them.

Hi Brandon,

Dark Screen

It sounds like a back-light problem. Check all the CCFL back-lights.

Vizio 46 inch black screen on left side

Sounds like you either have a faulty LCD panel tab, failed LCD driver board, LCD/t-con panel bad connection, or a bad t-con. You will need to get a diagnoses to be sure.

I have a 2008, Vizio VO47L 47 in. LCD TV. When I first turn it on, the left side(facing) of the screen is dark. Not completely black just shadowy dark for over an hour. Then it goes away, It used to last...

Faulty T-con board or mainboard (AKA tuner board)...the tapping would make me believe it to be the connection of the LCD panel to the T-con board that is causing the issue! This board is located on the top of the tv while looking down from the back. Replace it and you will be good to go!

Please rate if this helped :)
