[AC Question]

Dropped the phone, screen broke with no working touch pad - bought new LCD display with digitizer - swapped the motherboard over and the phone was working perfectly for around 4hrs... then for no apparent reason screen went black.

Touch/ vibrate/ sound all work - samsung logo comes on for a second or two when the phone is turned on then goes black. Same with battery logo when it's charging.

Got in touch with the replacement screen manufacturer - They sent me a new screen and i'm still having the same problem.

Any ideas much appreciated. Thanks.
