Chosen Solution

I replaced the screen on my 3gS with thanks to the instructions. It went smoothly except the old screen was a little tough to get off until I got the hang of it. However, now the slide to unlock or slide to power off is really hard to do - usually doesn’t work. Sometimes with a really light touch I can get it to work. However, the e, s, d keys no longer work. The other keys do work. The phone worked great before I changed the screen. I’ve tried re-seating the three connectors several times, no dice, same result. Any ideas on what to do? Update Problem solved. I got a bad screen. Ifixit sent me a new one right away and it works perfectly.

is it definately the right part? not for a 3g? try doing reset. press and hold power and home button for 10seconds, apple logo will appear then allow to reboot.

I contacted ifixit, they are sending me a new unit. Maybe I got a bad one. Good customer service on their part!
