The LVDS cable between the units mainboard and LCD is loose, or the LCD driver IC is on the way out. the only way to fix this is to reseat the cable or replace the mainboard

Samsung TV LN32A550P3F problems. About 4 minute after turning on screen displays some picture with vertical lines & a lot of louder white noise over the normal sound.


Please check sound on main power board. Could be a failing component that is heating and not functioning normally that is causing interference and thus the vertical lines.

Vertical line down screen


This problem can be caused by a lose connection between LCD and motherboard, however you can check it by opening the LCD or hinge bezel to ensure if there isn't any lose connection.

Flashing black and white vertical lines


Vertical lines in the display indicate a failing screen. New screens are expensive and not worth the labor and parts charges to repair it. It's new monitor time.

Colored vertical lines on monitor


Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

Gateway laptop vertical dotted lines across the screen


Sounds like a problem with the LCD assembly or cable. You may want to reseat the LCD cable at the LCD end. It could be a loose internal connector in the LCD assembly.

White vertical line in the center of projected image


I have a Dell 2400MP projector that had the same problem of vertical white lines appearing over the screen.

This may seem like a simple solution, and I don't know if this will work for you, but the way I solved the problem was simply to press the bottom side of the projector, until the white lines disappear . Until now, the problem has yet to resurface.

Here's some simple steps:
1. Turn on projector
2. Connect projector to computer
3. Focus projector
4. If white vertical line appears, firmly press underside body of projector
5. See if vertical white line disappears
6. If not, try slowly pressing other parts of the body of the projector and see if white lines disappear.
7. If solution doesn't work, you may need to send it to the service center.

Hope this solution works for you.
