Panasonic TH-50PZ77U 1 1/4" inch vertical line

My Panasonic TH-50PZ77U has a 1 1/4" inch black vertical line on the right side of the screen that travels from the top to about half way down the screen. I have the same identical plasma with a cracked screen that I can use the parts from. Any suggestions before I start swapping out boards?

This problem is usually the ribbon cable connection at the top of the stripe. Reseat the cable first. The other possibility is the panel itself, but that is rare.
Keep us posted.

A black vertical bar appears on my tv screen when I turn it on?


Hey!
With Plasma screens and just screens in general, that tends to be a big problem. Here is a link that kinda goes over the problem. http://adf.ly/1fNBRK . You most likely just have dead pixels which could either be a easy solder job or requirement to replace the screen. If you go with the latter, you might just want to buy another TV screen. http://adf.ly/1fNBRK

Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

How do i get rid of a black virtical line on tv screen or is this a costly repair


Very costly repair. A micro circuit has probably failed. Could be covered by your home insurance if the item was knocked accidentally from the TV table for example.

Vertical line down the screen about 2 inches thick


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

HOPING THIS WILL HELP TO SOLVE THE PROBLEM....
