Glenn, Did you scope the CRT for DC at the socket pins with the set off but plugged in? Does the spot extinguish if you unplug the set after shutting it off?

I actually tried shorting the 200 volt line after turn off with no effect. I looked at Q5004 as a possible culprit too with no success. The strange thing is if I pull the plug as opposed to turning it off the spot goes away. Dunno....anyone???

Good luck.

Adjusting G2 has no effect and if the chassis is swapped then the problem stays with the chassis and not the tube. This started happening about a week ago according to my customer..

Picture is normal when turned on. I dont see a spot killer circuit anywhere in this set and wonder if anyone else has come across this before?. BTW, if the power plug is pulled as opposed to turning set off from the control panel then there is no spot in the screen.
