Pioneer DV350 problem

I have the Pioneer dv350 (multi-region) which seems to output the picture to
my tv slightly to the left of centre.

I thought at first that it was the tv but everything else is ok - Sky
digital etc.

It is mostly noticeable on the dvd menus and on title sequences of movies
but now that I have noticed it, its started to annoy me.

Does this make sense or ring bells with anyone?  TIA
