Hi Fred,
Thanks. Yes, I do have another monitor I've been using for the Model 1
(see http://www.classic-computers.org.nz/collection/trs-80-model1.htm) ,
but I'm slowly acquiring the full system. So it's not that I just want a
working system, I'm wanting a working Tandy badged system.
In which case, the ancestral RCA information probably
doesn't give you
any additional help.
No, actually it might. The SAMS document, although it has a
troubleshooting guide, seems to assume a knowledge of how a monitor
actually works. What I'm looking for is this generic higher level kind of
knowledge. I could just follow the troubleshooting guide through step by
step but my monitor is 240V, while the SAMS guide is for 110V. There are
bound to be small differences. If I know, conceptually, what's suppose to
be happening, it will help. I might also stop me electrocuting myself! (-:
Terry (Tez).

True.
At least in USA, the TRS80 Model1 monitor is a slightly modified RCA TV
set. One of that specific model was visible in the background
occasionally on Al Bundy's kitchen counter in "Married With Children"
after many years. I've done no tests yet, but
I have Sam's Facts for the
model 1, and they provide a troubleshooting guide for the monitor and say

Until you succeed in fixing it, the TRS80 Model1 will work just fine with
a generic USA RS170 monitor, if you make an appropriate DIN to video
cable, or open the model1 and tap the signal.
