iPhone 4 Touch Screen is not working?
The iPhone was working properly, had never been opened and all parts were OEM. I was using it, then i set it down for a few minutes and when i turned it back on the touch went out.
I put in a different digitizer and nothing, then i a different motherboard with my digitizer and the touch worked. It's a problem with motherboard? iphone has been dropped many times but always kept in an otterbox.
