I had similar problems with my 4S. Changed the display, battery, and power flex circuit. Everything worked fine and then the display blanked on receiving calls. It wouldn't reset even after pressing the power and home button simultaneously although the Apple logo was displayed during the reset so I didn't think it was hardware related. I ended up reseting it to factory settings without restoring it with my backup. Everything functioned, even the proximity sensor so I went ahead and loaded my backup and it's been working fine for a day or so. It's too early to say it's fixed but it's looking good. I think somewhere along the line the firmware/software got corrupted and only resetting it to the factory settings reset the problem. After it resets to the factory settings it will ask you if you want to restore your phone's options. Make sure you say NO and don't restore your backup but select the "new phone" option. When it finishes disconnect the phone from your PC and see if the basic functions are working. If it looks good restore your backup and sync it. Good luck. Make sure you make a backup before you reset it to factory settings or you will loose all you data.
