The LCD inside my PowerBook 540c is a "Toshiba LTM09C017"...and I believe it's dead. I've swapped it out with

A greyscale LCD from my 540 (which works) and therefore I don't think the boards are the problem.

The Toshiba faded to blank white and it seems permanent...are there any retrofit LCD screens that might work? I found the same Toshiba on the web for $33 but I wanted to see if there were options. Thanks
