Just an idea other than long screw but did you check to see if you blew out your backlight? If you removed the screen with the battery connected and as you said pressed down and twisted the connector you may have blown out the backlight filter. If you disconnect the battery, reconnect it, hit the power button and then shine a flashlight onto the screen at an angle you may see the apple logo then your homes screen (it will be very dark). If you do see the apple logo or home screen then you blew the backlight which will require micro soldering to replace the filter capacitor. Good luck, hopefully this helps!
