Rear camera no image or shutter does not open.
After a broken screen replacement on a Verizon iphone 4 I noticed the rear camera isn't working. The front camera works fine but when you switch to the rear, it freezes, shutter doesn't open or no image black screen. I've cleaned contacts with 90% alcohol and let dry for hours. I've replaced rear cameras still nothing and I've tested all cameras on another working iphone they all work fine. So what am I missing, I've went over everything a hundred times. Is there a capacitor that needs fixing, please leave a picture of a CDMA iPhone 4 if that it, thank you.
