Can you give it any other color feed to verify if red is truly gone?
My 1084 (not an "S") has composite-in, or maybe it was chroma+luma.
but there were lots of different kinds of 1084's; yours might not have
one.

I've experimented with wiring my Samsung flat panel monitor's SCART
input to the IIgs' RGB.  I also found one color lacking - I think it
was green.  I bring it up because it seems like my GS put out a less-
strong signal on green.  I could re-wire the three colors and get
great results for any two out of three colors on my monitor.  Just
never all three at once.


Hi,

Well i connected the GS via the composite in and it only came up in
BW, so connected my xbox 360 and to be honest at first glance it look
ok, but then again it seemed a distinct lack of red in any of the
images (was using it as Media Centre extender), so watched so TV and
didnt notice any red and all looked slightly drab. Shame as the
monitor was it great condition. My mate has an Amiga so was going to
take it over there and see what it looks like.


As long as the color CRT red gun is still working, it shouldn't be
hard to fix.

You just need to find out where the interruption in the red signal
path occurs.  It might be as simple as a broken connection but no
worse than a dead transistor.  It certainly won't be an expensive
fix--as long as the CRT red gun is working.

There are "background level" controls for each gun--like separate
'brightness' controls.  That control may need adjusting, or it may
be intermittent or open.  In any case twisting it a bit may do the
job.

Use an insulated screwdriver to adjust the pot(s) and don't bang
on the neck of the CRT.  Stay away from the high voltage connection
on the bell of the CRT.
