The ribbon cable to the drive has either came loose of the drive itself went bad. You can open up the back if you are confident and see if adjusting the cable gets the line back. If not you will need to replace the Upper Y Drive.

Thanks

I have a 2" black line at the top of the tv. And also smaller black lines across the middle of the tv.


Dear Jeff,
It seems like the Horizontal IC in your TV is dying. This and the Vertical IC is responsible for displaying images on your TV. (Look at your TV through your Phone Camera and you will see upward scrolling lines.This is the Horizontal IC in action.)
I would strongly advise you to get your TV repaired immediately.

Horizontal black line running entire screen an 4 more lines running vertical


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.

A horizontal thin black line has appeared across screen.


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

I have a Phillips LCD tv just coming up to 2 years old. I now have a black line across the screen about 3" from top of screen. What is this and can I get rid of it??


You probably have a bad plasma panel. Have a repair shop check it out though because it could also be one of the buffer boards.

Faded section of screen


Is it an LCD or plasma monitor? If it's an LCD, it's possible that one of the fluorescent backlight tubes is bad. In some early ones, this is bonded to the LCD panel so it's not replaceable. Maybe it's under warranty?

Are the solid horizontal black lines or colored lines. If colored lines there is a posibility that your Y-main, and upper and lower Y-buffers are bad. If black you have a bad plasma panel.
