    help, i cant get my 3gs to turn on. i had a broken home so i bought a glass front with all parts fitted except the LCD as that was ok, i change all over and refitted and everything was working ok. i noticed i had trapped a lot of dust between the screen and glass so took it apart to clean out dust put it back together and now it just will not turn on. any advise would be grateful

    Did you maybe not plugin a cable when doing your cleaning?

    Sounds like Ribbon #1 isn’t connected.

    ive checked it again and all 3 ribbon cables are definitely in the sockets firmly

    could it be the lcd has somehow died, the cable doesnt show any damage

    Hold down home and power button for ten seconds. That will take it out of DFU mode and turn it completly off. Then just turn it back on. Good luck. Hope it works.
    Sorry if it doesnt. :)

    Tyler didnt tell you the whole story....its not in dfu mode. hold the home button and the on/off button down at the same time. this may take a minute! you want to hold both until you see that apple logo. make sure the phone has a charged battery or at least hook it to the data cable and to your computer with iTunes open. this way you will know if it is on if iTunes sees it. you may have to try this a few times but most of the time when the lcd is replaced or unplugged you have to do this to get it to restart.

    ok took the plunge and went to apple shop, apparently one of the connectors on the board was damaged so ended up paying for replacement handset
