Here's the short end of it. I cracked and replaced my HTC EVO 4G digitizer. Much more difficult than the vidoes suggest as whoever put mine together was glue happy that day. I reconnected all 3 cables (digitizer, screen, camera) and at first, it would boot, play audio (how I know it was able to boot). Now I have no audio. The screen stays white. If I swipe, I can change the intensity of the LCD (so I know something is working) brightness. Obviously the new digizers works. Ideas?
