HELP! Sanyo DS20425-02 wont display image!

[dethstryke]

I was adjusting the horizontal and vertical on my TV so the over-scan wasn't so terrible (couldn't see life bars on the bottom or top of screen) and as I was moving the image left and right the screen went BLACK. Sound still playing and everything, but no image. Did I "brick" my TV??

Please help!! I searched high and low and couldn't find anything. It's possible I didn't know what to search for exactly, but 10 different ways of saying screen went black during service menu turned up very little.
