Page 1 of Panasonic 28pk3 advice please.

Had a pk3 for 3 weeks now and generally very happy with it.

What I have noticed is when using av1 rgb for dvd & itv digital on a frequent basis I get a small oval pattern of vertical lines, that looks a bit like a fingerprint moving across the screen, in either direction. Is this the rgb problem that I have discovered in the forums that seems common with Panasonic? If so can it be adjusted in the service menu or do I need a call out//replacement. The set was bought from John Lewis in Southampton. Ideally i can`t use av2 s-video because the vcr is using this for q-link to work, one of the reasons I stayed with Panasonic.

Also do the service menu adjustments for geometry allow fine adjustment or is it a more overall thing?

Any comments or experience, including how to get into the service menu would be appreciated.
