I have had the light engine replaced recently on my Panasonic PT-52LCX65. Ever since then my TV's picture alignment has not been centered.

Lets say I'm watching 4:3 SD content, normally the black bars on the sides would be of even size. Now the left black bar is about a half an inch thinner that the one on the right. The picture as it is being projected has been shifted slightly to the left, causing bad overscan on that side.

Is there a way to adjust the alignment so it is centered with uniform overscan on all sides? I went through the standard menus but cant find a way to do this. Is there a service menu? If so how do I access it?

Thanks!

Casey
