Not sure if this is the correct place to post this so i apologize in advance.
About two week ago i accidentally broke the digitizer and LCD on my iPad 2 64GB. I replaced both the digitizer and LCD at the same time, please keep in mind that I HAVE fixed several ipad 2's before, from broken screens to full housing replacements. Now the problem with my ipad is that it will no longer power up... It worked perfectly before the screen broke! I figured the battery had to be completely drained so i put it on the charger for THREE DAYS and still no sign of life. I removed the logic board and used a multimeter to test the battery, it was reading .03v which i know is WAY off... My question is, which seems most likely to be at fault, Charging Port, Logic Board, Battery, or..?
YES I HAVE TRIED A HARD RESET BEFORE PULLING IT APART AGAIN.
