Iphone 4 does not work properly after replacement screen was put in

I do not know how to fix this.It appears that only the backlight is working on the screen. Nothing else shows up. The phone is recognized by itunes and I have already reinstalled the firmware. Any suggestions?

I recently replaced my screen also, but everything worked out fine for me. My guess is that you maybe messed something up with the repair or maybe didn't reattach something properly. You could open the back up again and see if you can see anything not how it should be. If you can't then you should consider taking it to a shop that does repairs.

  • Verizon iPhone 4 stuck on shutter after screen replacement? Only rear camera works? After replacing a cracked screen on a verizon iphone 4 the frontfacing camera is stuck on shutter, while the rear camera only works sometimes… I have tried checking the connections, as well resetting everything and even restoring. I have heard about possibly jumping something on the logic board but can't find where, a picture would be great.
  • My iPhone 5 speaker does not work properly? I have a similar issue and think its software related. Siri sounds very tinny in the iPhone 5 compared to 4s. Lock sounds, key sounds also much quieter but get better if you turn them off and on - hence why I think it's software prob. Same with external speaker and headphones. Please Apple release update. Call volume is great in mine, just Siri sounds terrible and low lock and key sounds.
