My thanks to you all. Apologies to those who haven't seen my previous
replies. It seems I have been responding directly rather than to the
group.

I have been through the extensive service menu options and found the
following settings (with service manual instructions):
Cathode (set to 15 for all picture tubes)
Colour Temperature (select Cool/Normal/Warm) [currently set to Warm]
Red, Green, Blue (set according to table for colour temperature) [they are
within specified range]
Red BL offset, Green BL offset (defaults 7, 6)

So I guess I could tweak the last two upwards? But relative to what? I
can't see an overall black level setting. Should I adjust these up and
the
brightness down, perhaps?

More importantly, Is this the best course of action? My gut feeling is
that
the blue level is so far out, that some component (hopefully a resistor)
must be failing? I have now had a chance to look inside and think I'm
probably out of my depth. Those circuit boards are packed and
double-sided.
If there's a faulty surface mount I don't rate my chances of finding it.
The microprocessor has no faults and no faulty components in its fault
log.
So I'm on the verge of giving up on it, but would welcome your further
thoughts.

P.S. again to those who haven't seen my previous replies this is a 28"
conventional crt, not a projector.

I sincerely feel you should stop at this point. You are in way, way over
your head. Most of the people in this group would have little trouble
adjusting the set in-person -- trying to explain it via e-mail to someone
who doesn't understand the basic elements of color-TV adjustment would be
extremely difficult. You need someone to step through this with you.

If you like, call me over the weekend and I'll try to walk you through this.

I just realized you're not in the States. So much for that.
