Are you sure it hasn't tilted to the left?
I recently had to use the tilt control to even out the picture. My F-38310 was leaning to the left, I got to where the tilt is and slid the tilt to the right. It has held that position for 3 days now. I hope that is it, for you don't have to enter the service menu for that.
Just hit menu and each button down until you see the word tilt, that's on my RCA yours may be 'simular' to mine. If your picture is doing anything else then what I described, I have no idea what the work around is for that problem. Good Luck
