I understand already that the position of the yoke affects dynamic convergence, but this thing was SOLIDLY glued in place, as were the wedges. I finally managed to break it free a few days ago, after much effort, but I wasn't able to find a position where the convergence was good all over the monitor. The best I could get was the center and top of the monitor having good convergence, but blue was still quite a ways off from red and green at the bottom of the monitor. |

Too bad about the Syncmaster. I fixed one once and it was a shorted (melted down) width coil.
I have found that if you have problems getting good purity and /or convergence on a CRT, its usually due to a slipped shadow mask. Usually resulting from a fall. Sometimes the cabinet cracks and sometimes it doesn't.

The place with the replacement CRT never e-mailed me back, so I'm not sure what's going on with them. |

Got a reply from the CRT place, finally. Turns out they sold off one of their warehouses a while back and didn't successfully remove all the part numbers from their inventory. They don't have the replacement CRT anymore. I guess I'll be stuck with a poorly working monitor now (I don't want to get rid of it because I like that the brand matches my XT clone, it'd just be nice if it wasn't so annoying to use with all those multicolored shadows all around the edges of the screen).

There's a NEC 17" Multisync 5FG High Resolution Color Monitor on a CL listing near me. (I'm as central as you can get in Ohio.) The listing is not mine, no relation, etc. It says very low hours. You can do a quick search for it, or I'll post the link in $/cents. I had one of these back in the day, and they're quite nice and sharp for a CRT.

This is starting to sound like a Hitachi TV i had years ago. The convergence got worse and worse and it had nothing to do with the yoke.
Again only thing I can recommend are pieces of magnet strips on the back of the CRT. |
