what i would try is:-
-first of all i would take the phone apart, including the home button flex itself, if you are unsure how to do so
iPhone 4S Home Button Ribbon Cable Replacement
this link should help, my best advice would be take your time, follow it step by step
-then once i had taken everything apart, i would look on the board for any signs of liquid damage, missing ICs and broken contacts. liquid damage can look like either white/grey discolouration or just plain brown dirt,
- then i would try putting it back together, as it is, if no joy i would then replace the home button flex or a home button ribbon cable (there can be a few names for it)

- then if changing the iphone 4s home button flex did not work i would then try changing the charging block(also known as dock connector) itself where the home button "clicks" into
iPhone 4S Dock Connector
these are the steps i would take, let me know how you get on

First step I would try is to simply just clean the charging port with Isopropyll Alcohol using toothbrush and lint free cloth. See if fixed, if not then I would clean the home button flex connector at it's charging port connector with Isopropyll Alcohol.

Craig, your assistive touch suggestion works for me. I am able to access the screen again. Dissecting the entire phone to reach the home button for a repair is the only other option...one which I now will not pursue. Thanks.
