I got iTunes to recognize after cleaning, but realized that the LCD/digitizer is toast, after replacement, and still nothing on screen I figured the backlight coil maybe IC was damaged. I believe I have correctly identified their location because I was able to swap the IC for one off an old 3Gs (a tad larger) and got my screen back! But no backlight :(

Can someone verify I have identified the correct coil? Also can someone verify the coil and IC are the same in CDMA and GSM before I buy a set? I have not found much data online about the CDMA version iPhone 4 or backlight IC and coil swaps.

Thank you for any guidance.

New IC and coil didn't work

Ohh dear, back to the old drawing board. The IC and coil change did not improve the backlight situaiton. The iPhone's backlight is still not working correctly, I can see if I hold it under a light and I know it's loading into iTunes. What else is possibly wrong? I realized several other coils look like they might have had some water evap and maybe burns?

Maybe try swapping them? Any further suggestions, I'm finding the CDMA iPhone or at least this one a bit more challenging to track down problems, but what else are weekends for. ; )
