Macintosh Portable lines on screen

[elemenoh]

I have a Portable with both a vertical and horizontal line on its screen. I have another with many lines in both directions.

I've tried cleaning the zebra strips with IPA and a cotton swab, but it didn't help. Below is a photo of the issue and a video of some suspect areas under the zebra strip on the left side of the display. I can't tell if these rough spots on the glass are expected or what sort of trouble I should be looking for.

Any advice?

You can either rip out the  screen, recap it or just use it like that. It looks good even with lines on it.

The original Gameboy is infamous for problems similar to this, but it is relatively easy to fix with a soldering iron. I wonder if the problem here is a similar one. Of course I wouldn't recommend blindly trying something like this, especially since the portable has an active matrix screen as opposed to the passive matrix one in the Gameboy, and it may have a completely different reason for failing in this way.
