My n900's gone all weird on me. The screen basically isnt going off at all. Its bright then dim then about to switch off and goes back to bright then dim... it keeps doing this. When i lock the screen using the double press of the Power button switch off then second later its back on. Same thin goes for the slide lock on the side. Ive flashed the FW and the emmc but stil no luck.

Any ideas what i should do?
