I just read a post that said tap on the top and the line will go away. I tried it on mine and it worked! I had to tap it fairly hard. I just kept tapping harder and harder on the plastic in front of the buttons and voila! The vertical white line disappeared!

SOURCE: White vertical lines in image w/ 2 inch black bar horizontal.

the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.

Vertical lines on an LCD screen are not a good sign. This usually means that your screen is going bad.

One day my tv started having white lines in various places, then one day the scrren went white but still has a small line across the top that works fine


Hello,

The problem is "Vertical Over-drive" and the white lines are vertical retrace lines. What has happened is a component failure between the vertical oscillator and the vertical driver circuit. The component is usually a capacitor that is leaking and allowing voltages to appear where they shouldn't be.problem component is leaking and allowing DC voltages to appear where they don't belong. It's causing the vertical driver transistor to run "flat out" and will ultimately burn out the transistor from internally generated heat.
Hope this help....

Half inch crystal/ solid white vertical line on screen


Adjust the horizontal in the menu then try the overscan adjustment. If the image does not look dim you do not need a lamp.

Vertical white line near the left end of the screen.


Usually when there are colored lines on the LCD its because the screen is going bad. Quick way to verify this, try a different monitor on your computer and if the line goes away then you know for sure the monitor is bad.

If you try a different monitor and the line remains then you know that the video card is bad.
