The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

Bad capacitors.

Vertical colors bars appearing and disappering are the causes by the board that call the T-CON board it is dying or the fiber optic cable that connected to it lose or damages internally.Mostly of the times about 99% of the times the T-CON board it is dying and it is not decodering pixels codes correctly anymore before it send those pictures pixels codes to the tv LCD screen panel.This T-CON board sit at the bottom in the middle of the tv LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a new refurbish T-CON board for the replacement.

If you get the black bar and it is vertical, not horizontal and it is on every input, your panel has failed. It is more economical to buy new than replace the panel. Try a Sony. Mine rocks.

(If the bar is horizontal, it may be an empty closed caption box)

I have 5 vertical black bars coming down halfway on the screen. Also 1 black square that appears on the lower half corner of the screen. What can I do to get them off? Please respond or call me @(510)938-6237 Shon Thanx!!!

The screen does not work properly .Ribbon wire fails.

It will burn into the screen overtime. The Akai units have a resistor on the address board that feeds the PDP that usually has a crack in the solder on one or both ends of it. There are about 4 address boards that are right below the panel itself and the suspect one is the board right below the line that is appearing. Have someone with solder skills repair it.
