So I had to take my N900 screen off as in a bizarre accident I got the metal frame bent but not damaged the phone in any other way. Anyway I have reassembled it however the screen isnt lying flat. It is up at the front towards the keyboard and closer to the bottom half at the top. I have tried different tensions on the screws to see if it changes the angle but with little success. Anyone know the secret to positioning the screen before screwing down to get the best results? A.
