Duo 210 screen artifact

[Challenger 1983]

Hello all

I was going use my duo 210 one day when suddenly I notice dead pixels, is there anyway of fixing this without buying a new screen

It's a common issue in early passive matrix displays - some sort of delamination of the LCD layers/algae?  Not repairable or removed sadly.

If you stacked a bunch of stuff on the laptop, its caused by the trackball. 

It usually wont show up right away once the pressure is relieved, but it does show up within days. 

In storage, I stack all my laptops sideways on the shelf.
