I just got my A3000 and has worked great (except improperly
seated expansion bus card causing yellow screen and no boot) but I do
have flicker in interlaced productivity mode.  I have tweeked the fine
adjustment pot all the way to the end of the pot but cannot get rid of
the flicker.  The books says that there is a coarse video adjustment
but that it should be made by an authorized service center.  In
looking at the schematics (magnifying glass in hand) I found a
variable cap VC470 that is part of the same circuit as the fine
adjustment pot (VR470).  Is this the coarse adjustment?  Can I just
tweek it or does the coarse adjustment require specialized test
equipment?  If its just visual, I can tweek just as well as the next
guy.


Thanks for any useful info
