I second the possibility of purity issues. Would much MORE suspect that from a set that I've had all apart and have been working around the yoke at all.

You also coulda just moved the set maybe WHILE it was on?....or maybe it's onboard degausing isn't up to snuff. (thermistor, degausing coil itself, etc). I'm a bit rusty on these things since I not worked on a color set in at least a decade, but I would suspect you HAVE to deguass before you even look at purity.

I'm not thinking convergence...since if I remember correctly, it presents as colors not "lining up" on eachother....more than "wrong color"

Feel FREE to say I'm full of it though if I need to be set straight on this. I do currently have a small 6" Sanyo solid state set that is also showing red up top...and I have NOT looked at it yet. It has a manual degauss button that is obviously working, but I also have a red hue at the top of that screen. My first thought was purity when I saw that.

I'd hafta likely look around a bit to remember how to do purity. I remember it being "blank raster.....everything down but red.....Yoke back until you see a red area, move yoke magnets till this red area is in the center" (then of course put the yoke back with a crosshatch so it goes back straight).

Am I at least SOMEWHAT remembering this right? (It's from when I did this in high school years.....like 30 years ago)

My collection is mostly "micro" TV sets, so they tend to ONLY be B/W....or some newer LCD sets (I've NEVER heard of purity or convergence on an LCD set...and certainly not degaussing). I do have a couple 5"-6" color sets I've just not felt like "playing with" yet. I hafta someday get into that 6" Sanyo "combo" set and fix this same "red on top" thing....because that is one of the sets I actually turn on and watch often if the big 55" Samsung is on another source like the VGA (HTPC)
