Convergence Problems

[Steve K]

Chip:

Bob spelled out the convergence routine pretty well. The only thing that I would add is that after you degauss the set initially and adjust for red purity, losen the yolk and pull it back (toward the CRT socket) as far as it will go and adjust the purity rings so that the red spot is in the center of the screen. Then push the yoke back toward the screen just until the entire screen is red. Sometimes if the yoke is too far forward the edges will be off.

Also make sure the convergence coils and purity/blue lateral magnets are lined up at the right place and position on the CRT...I can remember having problems on sets with seperate convergence yoke housings when it was positioned too far forward or back.
