Same problem with my iphone 4 Nothing on the screen except funny noise " bong bong" Tried restore with iTunes on Mac : no change Tried restart with home and start button : no change Tried to disconnect battery an re connect : no change Dismantled the LCD connections + others on the mother board and back again : no change ! Do not know what to do : usually it works fine but not this time .
Before logic board re assembly it is nice to use scotch tape ( temporarily) to bend all the connections above the battery compartment . Doing as such avoid to have the power button connection remaining below the logic board .
eventually , I got it right , after at least one hour , with the help of Jason : Tip : when removing this clip , take a photo of it for re assembly .Before re assembly : re bend this clip right as it may have change chape . Place the sensors , put the clip above and put the right side on position below the two sensors then , push gently on the left by bending away with a small screwdriver, release and it may be locked.
This clip goes above the earpiece assembly .To get away with all the cables , glue them away temporarily with scotch on the battery compartment.
Same for me :just pull upwards with your nails on both edges.
Excellent tutorial : be careful when removing the woofer connection : do it exactly as it is pictured otherwise you may harm the motherboard.

How to re install this little clip ?
Forgot how I removed it and now I am stuck for re installment ....
Unlock without removing them , the two remaining center 6mm Torx screws securing the display to the upper case.
