Do the lines go away with the bezel off? You could put a piece of foam on the screen behind the bezel. Sounds like something is loose and if you can't tighten it, you possibly can keep the pressure on the screen to keep the display normal.

The screen is fully damaged. You will have to get it replaced. Prior to that click a few snaps and transfer them to yous PC and check whether all the images are sharp and do not show any problem. Cause the service centre might try to get more money from you saying a different problem was found. If the images are fine. dont forget to mention the same to the service centre people.

Vertical lines in my laptop screen


This could be a failure in several areas along the path from the video card to the monitor.

Being that there is not an issue across the entire monitor the video card should be considered a last resort check.

Usually this is caused by a loose connection between the LCD driver and the LCD panel itself. Sometimes light pressure applied near the affected line will clear it up. If that does then it is a connection between the LCD panel and the connector to the LCD driver at the panel's edge.

Not much can be done unless you have it repaired by a professional or you can take it apart yourself and apply a pad of some type inside the monitor's edge to apply the needed pressure once assembled.

Parallel vertical lines through left side of Panasonic Plasma tv


This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

Plasma TV technical difficulty


if you can still see the picture its most likely the control board that's going bad, you will still need a tech out to fix the issue.

Vertical screen lines and resolution is in extra large format.


Possibly either or a hardware fault..
Does the pc have an external monitor port? Most do.. If you can get another monitor, plug it up and use the correct hot keys (keys on your keyboard) to switch between the laptop monitpr & the external, it might help diagnose the problem. Maybe select a generic driver for the external monitor.. Although the pc will probably pick it up ok. If you need further help, let me know. Rgds.

Printed lines shift to left and double images


Are the lines vertical? Have you tried to align the printheads? This can be done using your printer's installed maintenance software.

LG Plasma picture probles


hi there. I have this same TV, and the exact same problem. Last night, i was playing around with it, took off the entire back of it to see if I could fix it. After a few minutes of tinkering, I found that if I apply pressure to the TV in a specific way, the left side of the picture comes back. Here's what I did: standing in front of the TV, I hold the top of it, in the middle with my right hand, and the upper left corner with my left hand. Then, I gently apply pressure, forward (away from me) with my right hand, and backwards (toward me) with my left hand. Sort of like trying to "bend" the screen. At some point, the picture comes back .. . the problem is, if I let go, then the colored lines come back . . . maybe one can mount it on a wall in such a way that the pressure is still there . .. i haven't tried. That's all I got.
