Looking for XT875 Service Manual for Hardware Issue or info on Touch Screen

[twopumpchump2]

Hi-
In spite of replacing my touch screen it will still not respond to my touch (Although LCD display is fine). Does anyone have a service manual or info on the pin assignments? I am convinced a hardware, not a software issue. Any help appreciated...I am going on 4 years with this phone and really see no reason to get another.

You replaced the Digitizer or LCD?

Replaced both in spite of LCD working fine previously and I have several other bionics and have replaced the screens at least 3 times before so I think it is an issue with the motherboard or the pins
