Nothing, they are in original condition from three sources. Have not serviced these yet. Completely untouched and the storage conditions are the same for all of my PB 100 series, only the 150's are affected.What did you clean the displays with before they were put on the shelf?
Cool! I still have the old display from my Compaq Contura so I may try this.Good news is, you can get replacement polarizing film with adhesive. It isnt cheap but its doable and easily fixed if your careful.
I think it all depends on their previous life and exposures. I know alot of the PB170/180 machines had tunneling, but mine does NOT so it may have been stored differently.
Found a 145 at the office yesterday, exactly the same issue as my 150's. It could only be humidity related, three separate locations, all with the same."peeling" the film will ruin it. I have tried to re-use old polerizing film, and itll develop lines and marks from "peeling" and the inconsistent remaining adhesive will cause optical obstructions.
You can see it when off.YOWCH! Can you see the damage when the 'Books are powered down or do I need to go through my collection and test under power . . . those that'll power up. :/
Wow, just as bad.. Worse on some. Its like a bacterial growth. The last one certainly looks like mould, but I have a 180c with that "cracked" plastic too. Clearly something bad is going on =(Hi guys, I am sorry it took me so long to take the pictures I promised, but here they are. My collection of powerbooks was kept in two different rooms with our dehumidifier running all the time, because of a health condition. Since I am a chemist, it never even crossed my mind to clean the screens with solvents, so this can't be the reason for the excessive damage. Since last time I checked, the PB520 and Duo 2300c screens got even worse. The bright spot on the Duo 230 screen is not a flash light reflection, it is a polarizer damage. Any ideas of what might been causing the polarizer deterioration?

Yes, you can see it on the Duo 230 - it looks as a slightly discolored area, but if I have not turned it on I may have not noticed it. On the PB G3 no way to tell - it is only visible when it is on.YOWCH! Can you see the damage when the 'Books are powered down or do I need to go through my collection and test under power . . . those that'll power up. :/
Why not buy some new film and see if you can fix them? That’s what I’d do.I have a few more which screens are still OK, but I am worried that these too will fail. I wonder if I should stop collecting powerbooks and collect only desktops from now on.
