I hardly think this is worth posting, it's so silly.  But you did say
*any* insight... 

A while back my system began doing the same thing (2000, Sony
CPD1310).  Then one day I happenned to be fooling around with one of
those PAL boot utilities that came across the net.  To stabilize the
screen when swiching back and forth from PAL to NTSC required
adjusting the vertical hold control.  I noticed that by moving the
control just a little bit, I could produce/clear up an effect just
like you describe.  So, try fiddling with the vertical hold.

See?  I told you it was silly... :-)
