So I have a 50 Lg ( LG 50LN5700). There is still a picture however about every 3 seconds it goes from regular to blurry and repeats. There seem to be about 3 black lines across the top horizontally about 3...


To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

About two months ago my flat panel plasma tv


Most like likely, this is a panel issue and it will be too cost to fix.

Other things you can try, reseating the ribbon cables on the buffer boards located running across either the top or bottom or both. If that doesn't do it, replace those boards and still no luck. Panel is bad.

HORIZONTAL LINE THROUGH PICTURE


Defective LCD panel. I hope it is under warranty, otherwise you'll have to live with it or buy a new set, as the LCD panel costs almost as much as the TV itself.

Issue with LG Plasma tv model # DU-42PX12X


Another "same probelm"

My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?
