check if the line appears in BIOS...dont worry when i say BIOS...not sure how to check...turn the system off...restart the system and keep tapping the F2 key...you would get a Blue screen...check if the lines appear on this screen...if it appears...it could either be b'cause the display driver has gone wrong or the system might have a physical damage.....if the lines does not occur on this screen....it is a manufacturing defect...please contact the manufacturer and report the issue for solution....... regards Rocky
There are two possibilities: That the monitor is bad, or that the video board is bad.
The easiest way to test is to install a different monitor and see if it does the same.
If it does the same, then it is the video board. If not, it is the monitor.
It is the problem of monitor pcb in vertical section.check vertical ic for dry soldring. Resolder the ic if problem still on then change ic or check components related ith it. check continuity of vertical deflection coil.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.

What is wrong with your monitor is that the Horizontal section is going faulty, the lines you are seeing are the Horizontal Retrace lines, usually invisable in a working unit. It is often a faulty capacitor(s) OR a Diode breaking down.. in the area of the Flyback Transformer. Probably time for a new one unless ya can fix it yaself.
