Try to check your LCD connection that no pins are bent. Reseat the connector. That connector is very fragile and always be gentle when seating the connector as you can bend pins. Take a look at why I once lost backlight on a 4g Touch: https://www.dropbox.com/gallery/943721/1...
If it looks ok I would try to do a software reset. A lot of times you loose backlight or white screen if you reassemble and accidently have switched it on.

Right now it appears that you can not add anything to any repair or fix other then parts. Please use your profile to place your URL in there.
you need to change the coil, when the backlight blinks and finally dies thats usually the coil going bad due to moisture.

they might have done some mistakes in the wiring while removing the cracked screen. Or it might be something else.
