    I have an iphone, the screen smashed (glass Digitalizer & LCD) so i have replaced all and i now have no screen, i checked the connectors and all appear ok. 1 2 and 3, is there anyway i can test the new screen without trying it on another iphone as i dont have one to hand, i have cleaned and blew any dirt out and still have no joy the iphone itself powers and works as it connects to the pc and makes all the usual sounds i just have no screen it just stays black as if it was off. i have also done a hard reset to no avail does anyone have any tips to tricks to try? should i consider ordering another screen?

    thank you.!

    also does the phone need to be fully build and the two screens at the bottom put back in for the screen to work or can you just plug the screen in and power it up which it is still apart to check it its working. thanks

    um try looking at the #1 connector to make sure there is nothing in it .....i have had this happen before and what i did maybe it will work for you or no.........if you turned the power button on after putting the lcd assembly back in place chances are that it is still powered on ..try calling your phone and see if it rings and or vibrates if it does remove the motherboard from the back housing and then re-install the board and attach the screen agin and see if that works......... just read your post again remove the motherboard so the phone will shut itself off the put the board back in screw it down and re-connect the screens

    i have taken the motherboard out and placed it back in now, it still has no screen and also no power now but i think it may be because the battery has been left to go flat for two days, it was getting quiet warm when it was on before (yesturday) with no screen plugged in..... it is on charge now via plug socket, and it has just vibrated twice? but still no screen. any ideas other things to try... cheers.

    just plugged it into usb and is detecting again. but still no screen. is there a chance the screen is faulty. cheers.

    yes i purchased it comeplete, the reason for it being smashed was because it fell out my pocket and hit the deck, it does look like two of the pins on the screen are slightly smaller and have been pushed back but i think they would make contact still. do iphones have a graphics chip? im just wondering if i tried another screen it would still not work due to a graphics chip fault. but i do doubt it because it seems to power up and make all the right sounds when plugged into usb and that.

    could it also be posible that it was on when it was plugged in and it has shorted out and either blew a chip on the mobo or took the screen out. thanks for your responce again:)

    update: looking at the connector on the screen head on it would appear pin 5 and 7 are slightly bent in towards the base of the connector. could this have shorted it out and is now useless or if i bend them back and get them to make contact do you think the screen will still work? cheers

    Just Connect Connector # 1

    Just Connect Connector # 1 & see if the LCD lights up. Leave the Connector # 1 & 2 unconnected. You do not need to put the two bottom screws to check it out.

    If not working then your LCD is bust.

    I imagine your iPhone still rings when you keep it connected to the Wall charger with just the Mother board assembly.

    lcd

    what a lot of people do not realize is that you have to turn the phone off before you take it apart. you do not want it to fire up automatically when you start connecting the tabs. most of the time when the ear speaker stops working it is because it was on when it was put back together and it blew the proximity sensor.

    now, I had this exact same thing happen to me today. make sure the battery has plenty of charge. now, hold the home button down and the power button at the same time and do a hard restart. keep holding till you see the apple icon. but yes it is real easy to bend the pins or get some debree in there. :cool:
