Check for the graphics card whether it works properly .... my computer--> right click-->device manager..

The line is still there even when I unplug my monitor from my computer and turn it on.

If that is the case, I would say u need a new monitor.

I see GeForce 210 but no GTX 210 when I searched in Google. Anyway, what connection are you using? I haven't seen it mentioned yet. If you're using DVI, try VGA or DP. To be thorough, have you tried connecting the monitor to another computer?

This can only be one of the 3 things, the first two is what you hope for, the third is costly.

1. The lcd cable assembly is loose.
2. The inverter card may need to be reseated
3. The lcd itself has a thinline crack and needs to be replaced
