Okay.
So I have been having a few issues with the CRT on my Model III, maybe you fellas could help?
First off, when the screen is on, every once in a while, the screen twitches and zooms in and out a little. It's been doing this ever since I got it.
Secondly, I just replaced the old B/W tube with a Green one. Now, even with the contrast knob turned all the way down, there screen is mostly green. If I turn up the brightness knob, it goes away, but the image is fuzzy. And if I reset it, the green comes back for a moment, until the TRS-DOS boot screen loads, then it goes away again.
I have fiddled with the focus adjustment that's on the board to no avail.
I am good and truly stumped, any ideas?
Thanks,
Peter
