RCA Convergence Board - PW800

[joeseattle70]

Unfortunately, I don't have the test equipment to troubleshoot the convergence board, but know it has issues - not sure what else would cause this. Had a time getting convergence set up, and when looking at the tv screen, on the upper top quadrant, there is a bit of blue misconvergence (vertical lines), and the center line has a small amount of red showing, (vertical) and lastly, was a bear to get the blue horizontal lines by and large ok - still not perfect, but took a lot of effort. Does anyone have a convergence board, or suggestion as to what part of the board might be causing it? I suspect that it is the 3 coils that take the adjustment tool, but am not sure. Picture tube replaced last fall, and has good picture - just a bear to get fine adjustments 100%. Thoughts - leave it alone or try to get convergence board? Thanks!
