This page describes repairs for the HTC Desire HD (A9191) smartphone. I do not tell you how to dissassemble the phone as there are plenty of youtube videos that can show you probably better than i can describe it here. This page assumes that you already have your phone taken apart.
It is very easy to damage your phone beyond economic repair when messing around inside it so follow this page at your own risk!
