K750i White Screen of Death

[Overmind]

My K750i just went WSOD.
Very rarely it comes back to normal, but 99% of the time it's a white screen.
I flashed it with official SE software and updated to the latest 'D' firmware, but still no change.
Is there anything else I can do or is the display totally dead ?

UPDATE:
I opened it up; the problem was that the LCD screen was damaged near the contacts. Best I could do was to get half of the screen working.
Guess I'll need a new LCD.
