Why does my iPhone 3GS have an intermittent white screen?
I just finished replacing the battery, back, and screen on my 3GS. Unfortunately I broke the home button, so I bought a new front panel assembly. After replacing the front panel assembly I'm seeing an intermittent white screen.
The symptoms are that the iphone will turn on after a soft or hard reset, displaying the lock screen and working perfectly. Once locked, however, the screen will come on white even though the phone can be used (it makes unlocking sounds when swiped). Sometimes pressing the power button over and over will fix this problem.
I thought it may be a loose connector so I removed the screen again and reseated connectors 1-3.
The problem was not solved. I'm hoping that, because the problem is intermittent, I'm not looking at a logic board LCD chip failure, right?
What are some steps I can take to fix this problem?
