vertical lines in a Toshiba TV

[vol.2]

I've got this Toshiba set that died on me and I recapped most of it because it needed it. It seems like it ran quite hot in it's life and there were multiple burned areas on the PCB

I went through and replaced any bad diodes and resistors in the areas that were burned and stuff, and tested and replaced anything near a heatsink.

After all that, it works and generally looks fantastic and bright, but there is a visible vertical line pattern in the raster that appears most strongly in solid colors, and most strongly at a particular brightness. I would say just roughly guessing it's about 50 IRE bright.

I think possibly what happened is that I used some higher heat resistant caps because I wanted to be safer about it, but that maybe one or more of those caps are higher ESR or something and they are causing the lines somehow. Maybe not doing their job to suppress them perhaps.

Problem is I don't know what to look at here as I did them all at the same time, and I didn't notice the issue until a bit later.

Any ideas?
