I bought a replacement monitor for our Coastguard unit for $2 from our local Op.Shop (we rely on Charity, cash is hard to come by !) and occasionally it looks as if we are looking at it through rose-tinted glasses, but we rarely look at photographs anyway, so the occasional pink background to documents is no disadvantage
Word is that the connection is the problem, but screwed or not, wiggling it makes no difference.
C'est la vie.
