Hi everyone.
I'm having some trouble with a Wells 4900 that I was tube swapping (due to burn). I'm using a 19 in 1 board for my test pattern and whatnot.
Its probably easiest to let the pictures show the problem, but in a nutshell, the left side of the screen displays proper color, but as you go to the right, the colors are wrong (and yes, I've tried degaussing with a proper degaussing coil).
The old tube did not have this problem. I had one other CR-23 tube from a different donor TV, that I had thrown on a G07 and worked fine (aside from it having a bad horizontal width coil, but that's a different story...) and swapped that tube in, and same results.
The chassis has been recapped (and was running with the old tube). Is it possible I screwed up something with the yoke windings when swapping around? I wouldn't think that would affect the colors so much as the shape of the picture, but I'm trying to figure out the common denominator.
Is this maybe just a coincidence and something on the chassis is failing? I have a spare (supposedly working) complete chassis I could toss in there, but want to eliminate the rest as a problem before putting it in.
Thanks for any help!
