AC Question

Phone was left unused for a couple of months. When charging it got warm but would not function; no lights, nothing.
Installed new battery.
Now it warms up when charging but still no response: no lights at all.
Tried various combinations of pressing power button, volume up and down and the home button.
No improvement.
Suggestions please?
