Question about LG Televison & Video
If black strip anywhere in picture and boards replaced did not cure it---about only thing left is defective panel----black is bad, if it was a color other than that a board would cause it, I have worked on a lot of these sets under warranty---order all the boards and change and still black band top to bottom= bad PDP-----Plasma Display Panel.
Let me know if you have ever in career replaced a panel--symptom suggests a bad panel.

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
HOPE YOU HAVE A BASIC KNOWLEDGE OF ELECTRONICS....
