I spilled milk on my iPad 2. It was stuck in a boot loop. I tried to restore it in restore mode & DFU mode with no success. I removed the screen and saw some corrosion up by the camera and a little on the board that the rear camera & power/volume cable connect to (don't know what it's called.) It should also be noted that this is the "old" version of the iPad 2 with the clamp style power/volume cable not the new plug in style. I cleaned the corrosion on the board & camera but the iPad still wouldn't restore. Then I unplugged the audio jack/front camera/mic assembly from the motherboard & sucessfully restored the iPad. Everything worked except obviously the audio jack, mic & cameras (not even the back camera but I thought it was just because the curcuit wasn't completed.) So I ordered everything, audio jack, front camera, mic assembly, rear camera (just to be safe) & power/volume/mute flex cable. First I replaced the audio jack, front camera & mic assembly (since this seamed to be the main problem,) plugged it into the motherboard and everything worked fine. Great, I thought, until I opened the camera app and the shutter didn't open. So I replaced the rear camera & power/volume/mute flex, powered it on, opened the camera app & got a blurry image from the rear camera. I noticed the lense protector on the case was scuffed up so I removed the rear camera, cleaned it with a microfiber cloth & re-assembled. Unfortunately I got the same blurry, grainy image as before & when I tried to switch to the front cam the shutter wouldn't open. I checked my connections, everything was good. Next I tried the microphone, nothing, mic picked up no sound. So I tried watching a video and got sound out of the speaker & headphones. So now I'm stuck. I have no idea why the rear camera is blurry and the front camera and mic don't work. Could it be faulty parts? I ordered everything from Wholesale Gadget Parts, which I thought was pretty reputable (although there was a problem with my volume down button not clicking, it still works but doesn't click & they agreed to replace it.) Could the rest of my parts be defective too? Or is my motherboard fried?
