HTC Desire 700 Dual Sim Printed Circuit Board (PCB) Replacement

Introduction

Check to see if the indicator light at the top of the phone illuminates when plugged in. If the indicator light illuminates, the battery is likely at fault as it can no longer hold a charge (if this is the case, see the guide for battery replacement). If the indicator light does not illuminate when plugged in, the charging port may be faulty. The charging port, or printed circuit board (PCB board), can be replaced if the device if it is no longer responsive when plugged in.
