Hi everybody,

I am working on a CRT and chassis which was badly out of convergence. I've managed to get the convergence pretty good but when there is a large block of colour on the screen there are dots in a line that jump across the screen. If I adjust the screen size down the problem also reduces which makes me think it is power related (Capacitors?).It is marked NEC PWC958 and Yoke Board NEC PWC-799 connected to CRT 510UXB22. Any input would be appreciated, since all other functions seems OK for now I'm assuming I need to do the caps.

Any advice is appreciated

I didn't find the right solution from the Internet
