It means one vertical output line for vertical pixels for the screen controller is either disconnected or damaged. Most likely the screen needs replacing or the controller itself.

If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.

TV manufacturers know that a certain percentage of TV's will end up with dead pixels. I believe there is an app called UDPixel that can fix dead pixels on monitors and TV's. Google it.

If a LCD TV has vertical or horizontal lines, in most of the case the problem is a defective LCD panel.

Sounds like an impact to the screen. Screens can't be fixed.

How small are the boxes? If they're extremely tiny chances are what you're looking at are called pixels and they're stuck. There are several ways to fix stuck pixels, try the ways listed here- http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor

If it's not a stuck pixel(s) try resetting your tv to default settings by selecting ' restore factory default ' or ' restore default settings ' in the tv's menu.

I've seen this problem before and if caught early (usually only a few pixels), its fixable. But if it has already started forming a "line" it might be too late and you might have a defective LCD panel. Most of the time, doing the factory initialization helps with this problem.

(WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

1. unplug tv
2. press and hold at the same time “Vol –“ and “input” button on the TV set.
3. while holding those buttons, plug the tv back in
4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go
5. then at the same time press “Vol –“ and “Ch. Down”, you should see the service menu appear (if it does not appear, try pressing the two buttons again, it needs to be exactly at the same time)
6. Then use the “Ch. Down” button to navigate down the service menu until you see “Industry Init” (NOT Industry Init +cause)
7. Then press “Vol +” to toggle it to “ON”
8. Then “/////////////////” should appear.
9. when the screen turns GREEN, unplug the TV. Wait about 30 seconds, then plug the TV back in.
10. Then continue on with the initial setup again.

Sorry, you have a defective LCD panel. If your TV is still under warranty, contact Sharp to get the TV exchanged. Otherwise, LCD panels cost more than the TV is worth.

try to adjust Vs & Vsc within 5% of their spec on the power supply board when you notice the problem.
