Guys, thanks for the replies. Much appreciated. So are ALL active matrix displays affected by this problem or just some? And while the passive matrix displays aren't as stunning do they have this problem at all? How about the color active matrix display of the 180c? I would assume it to be worse. I actually found an online source for a new active matrix grayscale display for this PowerBook 180b, assuming they are actually in stock. I sent them an inquiry about it. It's a little pricey but it's purchasable. I also saw a thread where it was mentioned moisture may have entered the screen. I suppose this could also affect old stock, unused displays depending on how they were stored.
