A "next episode in this continuing saga..." just quoting Tom ;-) OK. Here we go. First of all - Simon wrote:

But When I received Your mail my Powerbook was already disassemled. ;-) I was quite impressed. It was much easier than I thought. Unfortunately I couldn't take any photos for documentation because I didn't have the camera today. And Many thanks to your detailed advices Tom. Without your help I presumably wouldn't have been able to do this. And a short comment - maybe also to others that want to disassemble their 500 series - I figured out that the easiest way to lift the front plastics was by starting to open it from the side borders. And I broke none of the little clips. Yeah! But now for what I've figured out. Well. Actually nothing more than the fact that my LCD still has the darkening edges problem ;) Some other findings: - The PB 540 (b/w) LCD has only one backlight at the bottom of the screen. - Tom gave me the advice to switch of the backlight in order to examine if the problems come from the CCFL tube. I did it the day before. I switched off the backlight and let the Powerbook run overnight. And it's definitively not a backlight problem. The dark borders still grew with the backlight switched off. You can take a look at a photo I shot the next morning: http://www.webkreativ.de/temp/pb540_lcd2.jpg - The next hint you, Tom, gave me was to look if the translucent sheet inside the LCD panel is ok. And it was alright. No curling at the edges. It was not loose or anything else. - And I've also checked every connectors. Everything seemed to be in right place. After reassembling the Powerbook nothing has changed. The LCD still has the same problem. I have now also recognized that wen I look at the LCD from a more flat angle than normaly I can figure out kind of inverted pixels and lines at the areas that are affected by the problem. Hard to describe. But it looks like there a several pixels of the LCD that are exhausted anyhow. So I think the only chance will be to replace the LCD by a better one - which should be no problem now. Because now I know how to disassemble the display... ;-) Thanks again to all of you Kai -- PowerBooks is sponsored by <http://lowendmac.com/> and...
