I have a laptop with the same problem with a lot of people, vertical lines 1pixel wide appearing on my screen. First it was just a line then 2 ,3 , you get the point! Now, after about 10 months of use, 45 lines and going!!! External monitor works fine.
Is there a way, besides replacing the LCD screen, to fix this?
My laptop is Toshiba Satellite M60.
P.S. This thing with the vertical lines is a really common problem. Shouldn’t Toshiba deal with it accordingly?
Unfortunately, the only way to fix this problem is replace the whole LCD screen. If your laptop is only 10 months old, most likely you still have warranty. The LCD replacement is covered by the warranty.
