I have this K7000 that aaaaaaaalmost works after needing quite a bit of work.
I replaced IC2 and IC3, all new caps, checked ratings for all resistors in the vertical and horizontal circuit, adjusted 50/60hz pot, H-hold, V-Size, etc. and this is as close as I can get it.
Hard to tell from this image, but the top 3" or so has folded over, is upside-down, and creates an interference pattern anywhere it intersects with any other image being displayed.
