First, introductions!
I'm a product of the 80's
In the lost generation. Not quite X, not quite Y. The end of the latchkeys, the beginning of commerical ISPs.
I've been called Mr. Fix It (and given a T-Shirt to prove it).
I am maintaining a Ms. Pac-Man conversion in an original Pac-Man cabinet for my friends' bar, but I'm not very experienced with CRTs.
A few weeks ago the display would start good, but snap to a green overlay with lines showing vertical fold-over during warm-up.
I ordered a cap-kit and replaced the caps that I could find. (two were labeled with 5xx numbers while I only have a 2xx, 3xx, 4xx, and 6xx board).
I did not replace the resistor or the pot.
After the cap kit, there was no change in the display, except now there is no snap. It has the green overlay from the onset of the warm-up.
I researched this a bit more and found a suggestion to swap the green and blue feeds. I did this on the yoke (maybe on the CGA connection would have been better?). Now I have no picture. I'm guessing this was a horrible idea.
I'm about to order an LCD replacement, but i'd like to get this CRT working again.
All four of the boards are in rough shape. Is there any way I can get completely new boards for this thing? Even if I have to populate them myself, I can. If not, what is the best way to clean them up? With the LCD in place I'll have a lot more time to work, and better lighting to clean and reflow everything.
