try plugging in another screen using the VGA slot at the back (or side) if this works then there will be a hardware issue with it and it would need to be sent away for repair with HP unfortunatly

Black screen Sony Ericsson K850i


Hi,

I just had the same problem. I tried everything including resetting the whole phone upgrading the software etc etc.

I was convinced it was a softare problem, but my screen only went black when i press the buttons on one side of the keywpad so i started thinking it may simply be hardware related.

I tried taking off the case but didnt have the screw drivers to do this.

Eventually in a fit of rage I threw my phone on the floor (Carpetted floor) and too my surprise the problem got better! I basically gave my phone a few more whacks and it started to work fine again.

I am not suggsting you start whacking your phone, but i imagine if you took off the case and re-fitted it this would work.

Good luck.

try tapping lightly on the tub that matches your color problem.
do you see it come and go? if so then you have bad tubes.
you can try to rejuvenate them but is not recomended.
