Television and Home Theater

I have a Sony KP-53HS30 RPTV and i think mi image is a little off center, i need to know how can i move it slightly to the right, you can really notice it in full screen mode (480i) but  in HD (720i/1080i) you can... 

Does any one has an idea on how to fix this?

thank you in advance!!!

We were watching the 5 year old rear projector TV and all of a sudden the screen went black but the sound was just fine. This happened once before and we turned it off and unplugged and restarted it right away. Error code reads 12 (no error) but I cannot get a picture back at all. I've let it sit for 48 hours and plugged it back in and still no picture. The picture was great ...then black. I've searched the forums but don't find anything similar so I'd appreciate any thoughts on what might be going on.
