The job and kid situation has really been making hobby time near impossible to find! However, I've been motivated to really come back to this and make headway since I restored a mid-80's linear stereo VCR in the meantime. I got the color purity set pretty good a few months ago, and then started trying for convergence just recently. I feel like I have a handle on the process- going the rotation of steps in the SAMS, touching up the center as necessary. However, I'm just not getting there. This isn't a matter of trying for perfection, it's just that there doesn't seem to be enough adjustment to converge reds and greens anywhere close to decent at the top/bottom/sides.
Today, I decided to pull the convergence neck board out and start checking components. I desoldered all of the pots and checked them. They all seem pretty good. 2 of the 300 ohm ones only go up to 290ohm at either end, but nothing seemed to be a failed part. They all did influence things on-screen. (as did the 3 transformers) I mounted them back up and that's essentially there I'm at now.
I DID see that a maybe 1/2w 330ohm resistor looks to have gotten hot, making it a little hard to identify the colors, It's measuring 390ohm in circuit. Maybe that's a sign that I should consider replacing all the presumably carbon comp resistors on the board. The SAMS is missing the resistor list, guess that'd have been too easy, but I should be able to do my homework and ID them.
Is there anything else on the board, or otherwise, that I should be looking at that could be making it impossible to get moderately close to good convergence? Thanks for reading along!
