Found an iPad 2 wifi 16gb laying on the side of a country road, it was inside a nice leather case but the digitizer and lcd both where smashed. I want to repair this and had some questions. Will the device work with just the lcd and not the digitizer? I know it needs the digitizer to be able to interact with it but I want to know if I purchase an lcd for it, see if it will even power on before I spend the money on a digitizer. Or does the device need to have the digitizer attached in order for the lcd to light up and power on?
