If you had matching TP2's it would make this alot easier, you could just swap screens. You could take the phone apart and clean the ribbons but be careful they all have tiny locks on the motherboard connector. Don't know if it'll help or work but its free and good practice if you do need to swap screens, and remember Sprint and VZN TP2 parts are interchangeable.
