It seems since replacing the screen the phone sometimes refuses to wake up when clicking the lock button, or when an inbound call arrives. The phone rings but there is no sign of life other than the ringing noise. If you then plug in the charger the screen will turn on and you can use the phone as normal. I've tried a factory reset on it but nothing seems to help.
I haven't replaced the LCD just the glass/digitiser, and can't think of a reason in doing so would break other functions of the phone. Can anyone help or suggest what might be the problem here? I'm a competent repairer and have replaced the screens on many Laptops, iPhone's and iPad's but this is my first encounter with a HTC.
I believe it is a stock ROM branded O2 - Details from the phone are ...
Android Version - 2.3.5
HTC Sense Version - 2.1
Software Number - 188.8.131.52
