Blotchy LCD screen

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

I fired up my old Toshiba Satellite T2115CS notebook for the first time
in two years or more and found that the LCD screen is blotchy: a much
darker patch in the upper center than elsewhere.

Do LCD screens deteriorate even when not in use? Any other possible cause?


Re: Blotchy LCD screen

No, not normally, unless exposed to temperature extremes or physical
pressure.  That is a very old dual-scan display (on a 486 notebook), and
some blotchyness is normal.  Now that everything is active matrix, some
of us don't remember just how bad some dual-scan displays were.
