What is this?

[miniman82]

This is the FJP I got from Hawkeye. The chassis mods for running an FJP in place of the CYP have been done, and the tube has been degaussed. WTH is this, I've never seen a pattern like this before. It's like the beams from the guns are somehow too large, causing a strange pattern on the screen. It's wierd though, I can almost actually get good convergence.

All the screen and background controls work as advertised, but all the guns will cause the same pattern to appear on the screen when advanced one at a time. Looks like tri-color chicken pox or something. Also, no amount of messing with the purity rings, blue lateral, or yoke will affect it.

Please tell me the mask is not bent...
