I hope this is the right location for this reply.. otherwise I'll start myself a thread :)
Earlier today I dropped my beloved Tilt on the asphalt in a parking lot.

The back cover came off, and left some good scratches in the bottom right casing. The "Wifi" and "Enter" keys somehow popped loose, and it took some work with a screwdriver to hold them down so that I could slide the screen over without ripping the keys out and getting them jammed under the screen.
After being dropped, the screen and everything worked fine. When i got home to fix the aformentioned keys, I turned off the phone. When i turned it back on, the coloring resolution is drastically limited now. I get the color gradient effect, where the screen cant seem to produce multiple shades of white and blue (in the ATT welcome screen).
Is there a hidden set of display settings i can get to and reset or change? Otherwise I'm gonna try a hard reset and see if that will fix my problems.
Thanks.
