Replaced display assembly, digitizer doesn't work in certain spots.
I just replaced an iPhone 4 GSM Display assembly (digitizer and LCD) and connected every cable correctly and fully. However, when tested, there are three small dead spots in the digitizer, particularly the letters o, i, and m.
What is wrong? and in the repair guide, it says to clean all connctions with a de-greaser but don't actually get them wet. How do i do that? I'm thinking debris in the connection is the problem. Thanks!!
Is this a good question?
