Let's re-think the temperature before you bake the second screen.

I'm not sure what the polarizing film is made from but here is common plastic film characteristics:

http://en.wikipedia.org/wiki/Polyethylene

Polyethylene is a thermoplastic polymer consisting of long hydrocarbon chains. Depending on the crystallinity and molecular weight, a melting point and glass transition may or may not be observable. The temperature at which these occur varies strongly with the type of polyethylene. For common commercial grades of medium- and high-density polyethylene the melting point is typically in the range 120 to 130 °C (248 to 266 °F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).

What is the lowest setting of your oven?

There might be some differences between the powerbook 170 screen and the 540.

The screen does go all black(when baking), I do remember that when I baked mine.
