It's the CRT.
I had another shop-rebuilt module almost identical, and swapped her's out with
mine. After a time, same symptom. Unplugged CRT,let cool while the set was still
on, came in good pix. When it works, looks nice. Must be an internal G2 screen
grid opening, because rapping the neck does nothing. Well now I have two modules
rebuilt...
