Stephen,
I can understand your frustration. I do believe that I have a firm
understanding of the problem. We must think interms of analog instead
of digital. Analog engineering is almost a lost art, and still very
sensitive. A noisy analog signal can give you more problems than you
can handle, and this is the core of our problem. Now the folks who
decided to use this style of connector may not have been in an anolog
frame of mind. (I'm not saying that those folks aren't competent, it
just that they may not have been prepared for the problems of connecting
analog signals) I, along with a couple of EE types around here, agree
that coax/bnc type connectors are the best connectors for the job.
So Stephen our problem is that the connection on the 'video output
module' (the board on the back of the CRT) isn't perfect. The connector
number is 5R9. The surest way to fix the problem is to hard solder the
connector. In other words take the connectors out of the plastic and
solder them to the posts. (be sure to insulate them with heat shrink
of something like it, because we don't want those to come together
and cause more problems)
Good Luck Stephen,
call me if you have any questions.
