New Display installed/reassembled (twice) Still no power.
Hello folks. I'm having some issues with my iPhone 4 that I recently purchased some replacement parts for. Here's some background..
My LCD was cracked after a few untimely drops. The phone was still working until one final, fatal drop. The big CLUE I will say is this, about 3-4 days prior to the phone stopping working, the LCD would randomly turn off and would only come back on when the phone was plugged in (car charger/wall charger). This led me to believe it was a battery issue, but when I dropped it one last time, the phone no longer responded to anything.
So, I purchased a few items. I bought a new LCD/Digitizer, new volume button/headphon
Am I dealing with a battery issue? Could there be another issue?
After assembling, disassembling, re-assembling, I have no noticed anything visually/physic
Please help. Opinions?
Kyle, just out of curiosity, have you check the battery connection and the dock connector with a multimeter? Have you checked for continuity on the traces? I believe that there is a fuse on the VCC trace to pins C3,C4 and D3 of the 338S0867 Power Management Unit. You can also download the iPhone 4 diagram from here and see what you get. I know this is more of a comment than an answer but I can not attach images to a comment :-)
Kyle, the problem you are having is the mother board is dead.
If the phone is not turning on with or without the charger and you have replaced the Digitizer and LCD.
There is only one other part that i can advise you to replace and that is the chargeing port but if that does not fix anything then like I said the mother board is dead.
