This narrows things down.
The colored blobs are normally seen at turn off & is usually normal.
BTW try the G-2 control on the FBT. Just turn it up a tad.

I have a lot of stupid questions since i have never really taken a voltage measurement on the CRT out of fear of damaging tools.

What is the collector and where do I find it? I'm also not sure how to measure the G2 voltage. I know of the G2 controls but not where to check the voltages.

Which G2 control and what is the "FBT"? Sorry about the stupid questions.
