Screen and LCD replaced and now just a white screen, please help!
About a month ago I cracked in the screen on my iPhone 3GS, I bought a new touch screen online and followed a You Tube guide at replacing it myself. This was my first error as when I was removing the LCD from the cracked screen I managed to damage it. I put it back in place and kept the new screen to one side. I reconnected the connectors 1, 2 and 3 and screwed the front back on. The phone turned on fine although because of the LCD damage I could only see half of the screen, it was however displaying the home page.
To prevent further damage I ordered a new screen and digitizer already fitted together so I could change it all in one piece, this seemed the most sensible option and pretty easy in comparison. Disconnected 1, 2 and 3 and then reconnected the new on to my phone. It all went back together fine but I turned it on and got the white back light with no picture. I plugged in the charger and it vibrated as though it were on but still didn't display a picture. I tried plugging in my old cracked screen but it was still displaying a white screen.
I connected the phone to iTunes via USB and it would sync as if no issues. The mute button vibrates as if no issues. The phone receives text message and phone calls but I can not see them or answer. All I get is the tone and vibration.
I have tried a hard reset (home and sleep mode buttons together) but it just turns the phone off and then there is a struggle to turn it on again, it only seems to turn on if it is being charged or connected to iTunes.
I have also tried the restore facility on iTunes and again no difference.
I have tried the original frame assembly and the other screen and digitizer but no difference.
Is it likely to be the picture feed from the phone unit or am I making that up...?
Either way is it wise to stop spending money on new LCD's and digitizers?!!!
Esta é uma boa pergunta?
