I am having problems changing monitors. The old CRT went out, and there is no repair possible the whole thing is smoked. The original monitor was a C-5470, Mitsubishi Monitor.

This is out of a CNC industrial machine, not a video game, but this forum seems to have the most knowlegable people in regards to converting CRT's, so that is why I am here.

The original CRT plugged in to a square plugin, but I have been able to determine the RGB, and the Horizontal and Vertical Sync wires. I cut off an old monitor cord and spliced my wires to the replacement monitor.

The screen should have three lines of text, It has three distinct lines, however they appear to be garbled side to side, the lines have a horizontal movement that speeds up and slows down occasionally.

I have adjusted every pot inside the monitor that I can find, with no change. I even hooked a pot between the horizontal leads from the machine to the monitor, trying to change them with no luck, after I adjust the pot a certain amount the screen just goes black.

I have attached a photo of the screen.

I would be interested in being able to convert this to a lcd screen also, if someone could lead me in the direction to do that also.

Any help would be much appreciated.

It looks like your monitor is set up to for med. resolution, and your signal coming in is standard resoulution. You could try and find your horz. hold pot and tweak that and see if that helps to straighten out your picture, and if it does and you got multiple scanning then i am right and you got mismatch sync's.
 
Thanks PacMan

Thanks for the response, I just got off the phone with a guy, that I think frequents this forum, I have an output of EGA, and trying to get a VGA to work, so going to look around for a EGA Monitor. If not he has a 17" monitor that will work, would like to find something closer to the 13" that would fit in the machine properly though, but if all else fails will go with the 17".
