Philips black and white tv’s in the late 60s did this very thing it was the lopt (or flyback) every time. If you can check your EHT it might be low. Replace the lopt and the black circle will be gone.
I really didn’t check the flyback final anode voltage since I did have a raster. If that’s the case it would be near impossible to find a flyback or even an equivalent one to replace it with. Anytime there’s a defective flyback or a deflection yoke where it’s not a simple fix, the TV is un-repairable to me. Thanks for your input.

Another dud crt, a real pity Ken. Spare parts I guess
GE never was known for quality.
Yep, spare dud picture tube also, I don't have one with the smaller pins.
My uncle would buy nothing but GE when I was a kid. God only knows why.
Every GE I find works. That's something.
