Fcarelli,
Your fail code(F2 E1) indicates that the ERC(control) is not seeing the touchpad assembly.
If you have checked the ribbon connection as you mentioned.
You should start by replacing the control panel.
It is the most common problem for your complaint.
(90% of the time).
There is a slight possibility that your failure is in the control, but I would not start there.
Good Luck,
