    It depends where the line is centered most, to the right or left of the center, there are buffer boards that control the vertical video, on the bottom part of the unit if you take the back off and look at the bottom part of the set you will see these address boards, they are usually about 2 inches wide and could be labeled J or K, if the unit is High Definition then you could have these buffer boards on the top part of the unit also

    it also happens if The Graphics Card is broken or cracked.

  • mastermind10 Oct 08, 2008

    You must have a CRT. What happened is that the vertical deflection circuitry has gone out or the yoke has failed. You see this line because the gun isn't scanning the sceen to paint a moving picture. Instead, it's just tracing back and forth in one spot. I have some clue about this because it was one of the most classic problems back in the fifties and sixties, usually indicating the need for a new electron valve or two. The problem still crops up, but transistor's reliability have made it rare enough that the average younger TV owner hasn't heard of it.

    also try this before reparing.

    try disconnecting it from the wall for 15 minutes, disconnect all inputs, then plug it back in - do not reconnect any inputs. Turn it on and see if the line is still there. If yes, then off to the store you go knowing its a fault in the guts of the unit. If no, then reconnect the TV input and see. If it reappears then the fault is the signal not the TV.

    you can try.

    hope it works......

How do you fix samsung ps50a457p1dxxu has black verticle line down centre of screen

A vertical line could indicate a faulty lower scan (long skinny boards along the bottom of the set) board, a faulty lower scan connection to the screen or a bad screen altogether!

I have a HL-R5067W Dlp. Turned it on and have verticle black lines. Eight lines then 1 1/2" space then Eight lines repeated across complete screen.

It sounds that dlp chip got defective and need to be replaced to fix the lines issue. Local tv repairman will help you to get it replaced if you do not have experience of tv repair.
Hope this info will help you.

Horizontal line across screen

This is called "Field Collapse". Line collapse is different (a single vertical line) in the centre of the screen.
But field collapse is usually a fault in the field circuit (possibly a field output IC has gone short circuit) or electrolytic capacitors have dried out. The same can happen in a CRT TV - looks as if LCD panels are the same way! I think you will have to take this to a service centre.

I have a verticle black line about 3 inches wide on my panasonic

Normally when a line appears on the screen of a plasma or LCD it indicates the TV needs repair. There are circuit boards inside the set that, if bad, will cause problems with the picture. The only troubleshooting the manufacturer will offer is to unplug the TV for 30 minutes. If that doesn't solve the issue, the unit needs service.

Call Panasonic at 800-211-7262 to see what they're willing to do for you. If you're under warranty they will service the TV for sure. If you're out of warranty they still might give you a break--they've been known to do that.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

I have a black line accross my LCD t.v. screen

if it is a thin black line then it is probably a line of pixels out. if this is the case, the whole screen will have to be replaced and that can get pricey. i would suggest that you get it checked out by a tv tech and get an estimate, but it'll probably be cheaper to just get a new one

Black verticle line

You most likely have a bad address board or the conntection is dirty between the address board and the PD (Plasma Display Panel). This is not a do it yourself repair as any damage to the cables to the PDP would require a PDP replacement.

Verticle lines on screen

This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
