Unresponsive phone after locking phone

A customer came to me after she dropped her phone. LCD looks fine, the casing is not too, not liquid damage inside.

The phone will turn on, work for a few minutes, then after you lock the screen, the display won`t come back on. Not even a hard reset (home plus power button) will bring it back.

It will start working again after several minutes of being left alone, battery plugged in or not.

I tried testing it out of the casing, with only the lcd, battery and charging port connected. Still the same behavior.

I haven't tried a software flash, it does seem to be recognized by a pc.

have you encountered anything like this before? My gut is telling me theres some small component on the mobo thats messing things up, but i don`t have the expertise nor tools to mend it. At this point i`m just looking for an explanation.

edit: after it becomes unresponsive, itunes will recognise it in dfu mode. maybe its related to the sleep/wake circuit?

Thank you ever so much for your time

Does the phone need an update? Have you tried to plug in a new power button temporarily to the board to see if that helps?
