CTM-644 convergence problem

(1/2) > >>

Hello,This is my first post on this forum (which seems very nice) as I've got a CPC6128 and a CTM-644 monitor, 2 days ago.I'm very impressed indeed, it is by far a better experience than with any emulators and the not perfect LCD monitors.

Anyway, the monitor seems to work nicely, except that there are some convergence problems. The red color looks out of focus around the lower right corner. That make things look blurry.How can I fix this ? I know there are some rings to turn inside the monitor, would they help, and if yes, which one should I try to adjust ?
At last, I know that CRT are extremely dangerous and I never go beyond adjusting the focus and G2 on them. I know what not to touch, but are those rings a danger if I touch them with the hands ?
Thank you !

Welcome to the forums!


I'm sure somebody on here will be able to advise you.


(Say @Bryce three times, and he'll usually appear!!) :D :D

Bryce:
Once usually does the trick. I'd suggest you degauss the CRT first before you start fiddling around inside. It may have just been stored beside a big speaker or something. As for touching things inside a running monitor - My advice : Don't!

I will follow your advice, my life's more important that this old piece of electronic, or at least I hope so -_-As for degaussing it, I can only perform it by placing a PC monitor in front of it, probably not the best way ...
Thank for the answer :)

I've got another question ...
I noticed that if I touch the 5v cable a little bit, the monitor brightness slightly change. What's the relation between this cable and the monitor brightness ?Is it worth (I guess it is) to redo the soldering where the cable is plugged inside the computer ?
Thanks !
