This morning the screen went completely black without turning on even after battery was taken out and put back. it responds to touch though.
i disconnected the flat cable that connects screen to mainboard and connected it again and it works for a while but after the screen is locked for a while (like 3-5 min) it goes black again. there is no image or backlight. hardware issue since flashing didn't help? something in the screen is taking final breaths? imo N900's are almost impossible to kill without frying or crushing them and spare parts are relatively easy to get
