My until-very-recently-working Amdek Color-I RGB Monitor (November 1983) has
given up the ghost. It was working perfectly the last time I powered it up, but
now it doesn't turn on. No noise, no hum, no glow, nothing, it's just silent,
as if it died in its sleep. (It's worth noting that it was left un-plugged
between the last time I used it and now, so I don't think it was a surge).
I'm embarrassed to admit this to the many old veterans on this list, but while
I have a good history of working with digital electronics, CRT repair is well
outside my scope of experience. Still, I'd really like to fix this guy and get
it working again, so I would greatly appreciate any newbie advice that anyone
has to offer before I open the monitor up and start poking around (ginerly, for
fear of dying). My first step was naturally to google 'Amdek +"Color-I"' and
'Amdek +"Color-I" +manual', which unfortnately hasn't been at all useful. No
service manuals to be found. Other pointers would be very welcome!
I know that poking around CRTs has given a lot of electronics hobbyists a good,
non-lethal education. I'm hoping to follow in those footsteps.
