I've lost the backlight on the screen on my 9900. It's amazing how difficult a touchscreen can be when you can't be sure what you're touching.
I know the screen still works, because if I hold it under the light JUST THE RIGHT WAY I can see what's on the screen. Sorta-kinda. I was actually able to even take a picture with the camera.
Is the light replaceable on its own? Or is it sealed into the screen?
