SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

It sounds like the Screen is coming to the end of its life. Has the screen been recently moved or dropped? Plasmas tend to lose its contrast after 60,000 hours of use. It could also be a loose connection from your source to your TV. Have you checked all your connections to the TV?

SOURCE: Vertical Line started on left side of HDTV, and now

This problem is down to the actual LCD or plasma screen, if this shows as the screen warms up and stays on then the screen will need to be replaced, you should go back to your retailer (not manufacturer) and report this problem, depending on the store and how long you have had the tv, the tv can be replaced for a like for like tv at store as this is not a cheap standard repair.

SOURCE: horizontal black line

Hello
This type of fault in Plasma TVs are of power supply regulator capacitors. If any one of these DC capacitors, go low in rated value, proper smoothin of DC power does not occur. and black bars across the screen fro top to bottom will be the result. Just check for any capcitors of it power retulator side for bulged out or leaky. You have to open the TV to see whethere there is any of them is damaged. OK.

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.

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .
