w890i blank screen

[whone]

Hi!

I have been searching for a while now for a solution, but with no luck.

The trouble is that my w890i has a blank screen and when i start the phone a red ligth is shining on the back next to the camera.
You can play music but you dont see anything on the screen, the keypad lights up also and the phone vibrates on start.
I have change the lcd and the big flex, but no luck, still the same problem.
Have also tryed to rehot an ic on the board, no luck.

I have read about setool, but i dont know how to use it and if i must have a box to be able to use it or if i only need an usb datacable.

I dont know what to do now, so please, anyone, a solution for this problem and i would be very happy.

Thanks in advance, and this is a great forum.
