iPhone 3G: iPhone 3G completely died for no reason

Fri, 27 Apr 2012 18:42:57 -0700

Hi my iPhone 3G just went completely blank (black screen) yesterday. It wouldn't reboot using the top & home buttons nor by charging or connecting it to iTunes. Nothing drastic has happened to it. It was fine fully charged on my desk one minute & dead the next!

Anyone know how I can bring it back to life?

Thanks

iPhone 4s - screen replacement: The new display is lit, but its blank

Fri, 05 Apr 2013 09:49:02 -0700

I ordered a iPhone 4s replacement display and followed the guide for replacement successfully. When I turned on the phone again, the screen lit, but it was blank. I did receive phone calls and it seemed to be working.

I tried hard reset with Power and home button depressed. It didn't work. I disassembled AGAIN and checked all connections for looseness or damage. No problems seen.

There does appear to be a 1/2" slightly gray line running vertically in the center of display. I could swipe to shutdown phone (blind) and answer the phone with a bottom swipe of the screen (also blind). The screen is definitely lit too. The new display literally went from the bag to the iPhone, so I didn't "over handle" it. Could the screen from iFixit be bad?

iPhone 4: Blank screen after screen replacement, but phone is still working

Fri, 17 May 2013 08:07:43 -0700

Hi People.

First off let me say, that i have changed 60/70 screens succesfully already.

Anyways, got a broken iPhone 4 32gb from one of my brothers friends, with a broken screen (cracked, could light up but displayed no image). I don't know the history if the phone. After taking it apart, it is clear that someone with no skills whatsoever has been messing with it, and the screen was not an original one. Several screw where overscrewed, the clip for the battery is missing, the speaker is semi-broken, and only 2/5 screws for the top cover is still there.

Anyways, after having installed a screen that i know works (tested in a different phone), the problem is still there. It lights up, but shows either completely white or rather obscure colors.

I was able to take a couple of screenshots with it, and after hooking it up to my computer, these show the "insert SIM" screen.

I can't activate via iTunes, but iTunes recognizes it as an iPhone.

The water-indicator is still white, so I don't think it has been in water.

Any ideas as to what might be wrong? I have checked the connection to the screen 4/5 times and tested with a different screen, same result.

Thank you so much!

Regards
