Re: 1 thin horizontal line across Laptop lcd screen
Well, I can think of a couple of reason for that behavior:
- one pin of the ribbon cable went loose (cold solder joints), which are a pain to fix
- a micro break in the LCD glass that cuts an entire line, or transistor inside the glass that activates the entire line, is dead -- can't be fixed
- video card artifact - check if the external VGA output port shows the same line
- the board that converts the analog video signal to digital is broken - diagnosed through elimination
Basically, go to a service and ask them to test your laptop display on another board, and see if the problem persists.

Probably driver chip on panel flex failed -- would need screen swapped.

Could be delamintation of the ribbon cable to the panel. Try gently squeezing around the edges where the line goes to and see if that affects it at all.
