No display after repair
I've googled everywhere, and scoured this site for an answer to my problem. My problem IS like a lot of the other questions, but the fixes don't work. I can turn the phone on, hear sounds when I plug it into my MacBook, shows up in iTunes, and it vibrates when I flip the silent switch. The only problem is having no display/backlight.
My friend brought me the phone after finding it laying on the ground with a cracked touchscreen. Everything else was perfect on it, display lit up and everything. I replace the touchscreen, reconnected and it worked fine! Here's the kicker. The Home button wouldn't work, so I pulled it apart to fix the button contact but the #3 cable came loose. I have all the flex cables secured with dental wax (random, but it works and isnt too messy). I tried:
A. Holding Home+Power for 10s or until Apple logo shows
B. Removing the logic board for 5-10 min away from the battery.
C. Doing a full restore
Sorry for the long post, just wanted to give as much info as possible. Can anyone help me? He needs the phone back in a few hours, and I'm at my wits end. Also, this is NOT my first repair on an iPhone 3G. I have had MANY successful repairs.
Is this a good question?
