Nokia Pictures/Videos :: X6 Camera Screen Blank And Flash Doesn't Work

I have problem with my X6-00 16GB primary camera. When I turn camera on, screen stays black, only this focusing white box and other symbols are visible on screen. But no picture. When I push "take picture button", then focusing box starts blinking and stays like this, until camera goes standby mode. Secondary camera, in front of the phone is working fine. Also I have a Flashlight program (Brightlight v1.0) on my phone and it doesn't turn camera flash on, like it should be.

I gave my phone to friend who reset phone to the factory settings. After that camera worked for a while, but one day it was again black. I have done a couple of times software reinstall with nokia ovi suite on my computer. After that camera works couple of days or only couple of hours and then goes black again. Software version is the newest for that phone, v32.0.002.
