I have identical color changes with a KV-27TR10. I have poked at the
de-gaussing control device and the individual color drivers with negative
results. I have yet to try de-gaussing. I plan to try it with a soldering
gun powering a couple coils of #14 and waving it around the face of the CRT.
Available time is a problem with me. I have the Sam's photofact on it. If
you succeed, please keep me in mind. Jules Beaudoin
