Possibly a faulty screen. If it is, replace the screen.

SOURCE: vertical line on screen Lenovo T61 Laptop

You have a dead column of pixels. The only solution I'm afraid is to replace the LCD screen.

I'm sorry the news isn't good but can you take a moment and rate the solution as fixya even if it wasn't what you wanted to hear? Thanks! :c)

Generally a screen defect.

You can attempt to reconnect the cables going from the system board to the LCD by removing the screws on the bottom for the Keyboard, Palm rest, and bezel. The system board connection is hard to miss, usually centered near the top on Lenovo's.

SOURCE: black blob on bottom rh of screen,vertical & horizontal lines

The blob is a phisically damaged part of the LCD screen. Unfixable, the screen must be replaced and it will be expensive.

How can i fix white screen in my lenovo T420


Can you plug a monitor into the external Video connector, and do you see a display there? If you see a display on the external monitor, then the LCD is most likely bad.

It's a bad LCD. Replace it. Horizontal or Vertical lines are indications of LCD issue and can only be resolved by replacing the screen itself. Same with dead pixels. Sorry!

Vertical and Horizontal lines are indications of LCD screens going bad. Unfortunately, there is no solution for this other than getting a new screen installed.

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch
