The liquid forming on the screen I have found and the smell is undeniably acetone. Im assuming the glue used had an acetone base. Stupidity. 

Did you end up finding replacement polariser?

All of my batteries are removed and have been for 10+ years. This is not. Battery issue. 

What does it look like, its very hard to tell from your photos of what the issue is, is one of the plastic layers just shattered? 

I don't want to sound like a dullard/luddite, but what kind of troubleshooting can you recommend. Visually everything checks out, do I start looking for shorts to ground?

Hi Everyone, My Powerbook 270c wasn't working and ticking, so I cracked it open and saw that the caps were leaking. Removed all the SMD caps, cleaned and replaced with Tantalum. There was no change. So I washed the whole board and the unit still is not powering up with this buzzing from the...

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 =(

You can see it when off.

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. Surely there must be a way to remove, clear off the old adhesive and even just sit the polariser over the top?

I just recapped a leaky 270c but the ticking continues. Anyone kow any other common issues in the DC circuit? I did wash the area with pure Isopropyl to assist prior to install of of the new caps.

I've recently had amazing results with Loctite precision super glue. Its a watery glue in a vial, it's ability to hold weight and super fine properties and grab time for me have fixed numerous little issues in my collection. I have not used it on the display housings yet, but its first in line...

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.

I doubt it. Its melamine and it would have affected the other 12 machines stored directly next to them but didn't.

All of them from different sources. They were stored 20 meters apart and the only thing that is similar is they sit sideways on Ikea shelves. I always store my machines sideways to prevent damage to the LCD's if you stack them. The only thing that comes to mind is that humidity might be a...

I can only think that, but it doesn't explain why my 140, 145,160,170,180c,2400,250,2300 all sitting with them are fine. It's just the 3 x 150s affected. Arggg

I wouldn't until we know what's caused it. Hopefully someone else has seen this before and we. An correlate something that's caused it

Seems like the polarisers are de-bonding and the layer underneath is cracking from the gas- it must be a chemical in the glue of the polarizer 

In my living room 2 units and bedroom another 1. They have no batteries installed and. The right hand side and middle of LCD is purple and white with blisters under the LCD polarizer. I'll post a pic

So I was showing some people my collection yesterday when I pulled out my PowerBook 150 and the screen was all bubbled and warped. I pulled out another, the same. Almost like heat damage! i went into my storage in another room and a third Pb150 was the same, bubble in the screen and what looks...
