Hi,
This is a really cool forum!

I bought a W850 off a friend and had a few days and it suddenly got a blue tint screen and the graphics scrambled (ie. part of the bottom screen was on the top). I did a master reset and then it just went to a white screen. The phone itself works fine (I can hear all of the keytone pads and play music etc etc) but the screen shows white. Now and then it will show the blue tint screen but usually goes back to white.

I've trawled the net and found people with the same problem but don't know what the outcome was of solutions given. I also tried reflashing with XS++ but it didn't fix the problem.

Could someone please give me advise. Is this a hardware or software problem?

Thanks heaps!
