Sure it's not a CT35G25
B?
What is the input source? The reason I ask is that someone else seems to have had your problem:

I've got a Panasonic Viera that has horizontal shift - but only on DVD or Converter box. Off air, it's centered. Dunno why it shifts to the left - I tried all modes - letterbox, fill, or 4:3, all the same. I did find a document in Portuguese that suggested the horizontal count-down resonator may be slightly off. (Horizontal frequency is determined by crystal resonator off of the jungle chip in mine)
Do you have access to the Sams? (4548)?
