I bought this 34" behemoth of a CRT used a few years ago and had to adjust convergence at that point as it was pretty far off. It's been fine for years, even through two moves, but today I noticed that it's way off again (almost 1/2" horizontally). The blue is separated to the left while the red is separated to the right, so I thought for sure YBWU and YBWL in service mode were going to do the trick. But, when I went to adjust them, nothing happened. I tried moving both values all the way down to 0 and all the way up to 63, but there was zero visible change.
Is it possible the dynamic convergence system has failed? If so, how hard/expensive is that to repair or replace, and where would I go to find information on how to do it? I've heard that the minimum cost of getting a technician is probably close to twice what I spent on the TV to begin with, so that's probably not an option. But, I'm sort of a EE so I may be able to work out the fix.
