View Full Version : Odd (to me) monitor issue

May 20th, 2012, 02:58 PM
I have a Commodore 1084 monitor that has a bit of an issues. If I set it to composite video it works fine. If I set it to RGB (analog) then the red is shifted almost one char space to the right. Anyone have any ideas ?

i assume its not a lose connection?? Does the cable have any sign of damage (http://www.howtobuildyourowncomputers.com)?

Sounds like the delay for the red signal is off. If you're 100% certain it's the monitor, then I think it can be adjusted by turning some potentiometers on the yoke board (board that connects to the end of the CRT, I think it's called a deflection circuit). Of course, it is very dangerous working inside a monitor so make sure to take precautions or take it to someone who knows how to safely work on monitors.
