No obvious damage- changed home button still no response. All other functions OK just does not respond to home button. Can't locate schematics any ideas?

Located shorted component from Home Button connection between Cap and GND - removed that and replaced with cap all working now.

Many thanks, located the issue ZD5014 was shorted, replaced it with a Capacitor and Home button function restored.
