If this doesn't work, bring it to Apple Store or 3rd Party service vendor.

Good Luck!

Normally, if a Reset doesn't work, then it would be hardware and replacing the screen at any 3rd Party service would be the way forward, and while you are there, ask for a Hardisk upgrade and a battery replacement.
