Hi evryone

Yesterday when I was using my N900 and unlock the screen, it show up with "tearing". But it works fine when I lock and unlck it again. About meybe 4 time when i unlock my phone the screen was black, can't see anything :C

I dissasemble my N900 to check, if the tapes are fine but I can't see anything wrong with them and still nothing. The phone are fine, the touchpad was fine, leds but no screen.

Don't know what to do now? Can i try to reflash it? Or it's for 100% screen problem?
