Hello everyone, this is my first post here. I've been a lurker for quite a while now and personally have have a wonderful experience with my N900 up until now.

Recently and somehow annoyingly my N900 got a lot of dust under the screen. Instead of taking it apart myself I took it to an apparently 'Authorized Nokia Service Center' (I won't mention names for the sake of discriminative purposes)

I asked them to remove the dust that was under the screen, I'm not just being picky about the occasional bit of lint under the screen, but there was a lot of this dust. The removal of this obviously wasn't covered by the warranty so I had to pay.

When I was returned my N900 all seemed fine until yesterday when the screen kept snagging and wouldn't open fully and felt loose. Then I noticed that one of the screw heads had been snapped off. I had read about screws prone to snapping elsewhere on the forum.

I was wondering what my options are now. It seems clear that the guys who worked on my phone were incompetent and were certainly not Nokia approved. To make it worse, when I confronted them I was shrugged off as I had no proof of purchase since they didn't supply me with a receipt.

Seeing as this now makes my warranty invalid, is there anyway that I could remove the broken screw(s) and replace them with new ones? Yes there's more than one of them broken. (Top left and bottom right of screen assy back plate

I was also curious. Since it's going to be difficult to drill out and re-tap a 2mm ø screws, is there anywhere I could just buy the screen assy (which contains the stand-offs for the screws), and also buy replacement screws so I can do a much more professional job myself?

I looked at here, but they seem to be out of stock of screen assys and don't have screws.

Thanks in advance for any help you can provide me.
