Faint Black Line down the middle of TV

I have a 42 Aquos LCD and there is a faint black vertical line in the middle of my TV. You can only see it if the background is a light colour. Is there any way to get rid of this or is this the start of a problem with the TV?

Same problem on the right

Re: Faint Black Line down the middle of TV

Sounds like it could be pixel problems or board problems, this depend on the location. Most are mostly to the left or right, or going across the set to the upper or more to the lower side. For more info visit

SOURCE: Faint Black Line down the middle of TV

I have a verticle line running up the right side of my 32" Westinghouse LCD screen. This happened only 6-7 weeks after I bought it. I thought maybe it would go away but it did not... Interestingly, I found that it is exactly where the screen changes from 'normal' mode to 'extended' view mode.

In other words, when viewing the picture in 480 normal mode, you have black on the left and right side of the picture. At that exact line on the right side, is where the permanent black line appeared.

I called the company, and they said that is it NOT an uncommon problem. He said to fix it, I could hook up the tv to my computer and send an all white picture to it. Essentially, burning out the black line. He also said if I couldn't do that (I don't have that cable currnetly) that I could unplug the tv from the wall for 2-3 days...that should also fix it. As this is my only tv, I can't do that...but I am going on vacation in a couple weeks, and I will unplug it while I am gone.. He said if neither fixed the problem, that I should call back and they would deal with it. It is under warranty thank God.

Maybe someone else can try that on theirs, and see if it fixes the problems for them.

I have a brand new 1day old 60inch sharp aquos led tv since we hooked it up it has had a faint greenish line going vertically right in the middle of the screen. nothing makes it go away. do you know what...

This greenish line is due to physical screen damage. This is not repairable and not your fault.

If you didn't drop this tv, then the TV was damaged in the box.

Return your TV to the store you bought it as soon as possible. The longer you wait, the more chance they'll tell you that you damaged the TV and that they're not responsible for customer's physical damage.

Faint black lines going from top to bottom when tv is on for about the first 15 min

If I'm understanding this correctly, you have a faint line, horizontally on the screen that moves vertically right? if so, It's AC noise. If you are mechanically inclined, the quickest fix is to replace your current AC outlet with a GFI outlet. Works 99% of the time. Hope this helps.
