From the LCD replacement hunt thread:
I'm wondering if
plasticizer leaching within the close confines of a closed PowerBook over many years may be the culprit? If they're worried about the effects of leaching on drugs and foods for human consumption stored in containers within their expiration dates, multiple years of it concerns me. Dunno, but it seems to me it wouldn't take much to eat away at thin film plastics and adhesives? The variety of storage situations across environments and continents has made this my primary suspect.
As a chemist, hat do you make of that notion, techgeek?
