Hey, just wanted to share how proud I am of my "extreme" repair.
This PB100 screen has a problem I don't really understand.
At first I thought I caused it, but the more I looked at it, it seems I did not.
I got the PB100 is a sorry state ( yellowed, stuck hard disk heads, needed a complete recap , and... screen was you see it )
The problem is that the opaque paper just behind the backlight has somehow "melted" on top of the LCD glass.
This was a difficult repair as that thing really melted on top of the glass for whatever reason
I cleaned that residue with Acetone (after carefully testing) then quickly wiped with IPA.
I then created a new silk screen out of translucent paper I found in my daughter's school stuff.
That's the original paper there, with the horrible stain/melted zone. And the cut I did to replace it.
And here's the result
(ignore the white balance which differs - the screen color is the same as it was)
I can live with the 30 or so dead/red pixels in the middle - due to impact of the trackball ( thanks @desertrout for the explanation )
Just shared this in the hope this helps someone in the future.
