Replacement digitizer assy works fine until SIM card is inserted

So I replaced the digitizer/glass/lcd assembly and tested it at each stage of the install and all worked well. I then got it all installed and cleaned up and everything worked just fine. So I took the SIM card out of my back-up phone and stuck it in the S5, booted up the phone and now touch is not recognized. I tried everything including a factory reset to no avail. If I pull the SIM, the screen works. If I replace it, the screen works, but no touch is recognized.

Any thoughts?
