I found out what's going on. I did look inside the TV - everything was factory clean, no bad solder joints or loose wires, etc.
When I powered the TV on, I saw the problem - something is arcing at the very back of the neck of the CRT, where it connects to a socket on the circuit board where the flyback runs to. It's a small purple arc, emanating from under a blob of epoxy covering part of the back of the neck of the CRT.
I attached a picture showing where I see the arcing. I can smell ozone when it's turned on. I would assume one of the leads exiting the tube is broken.
Something interesting; it turns out the CRT was actually made by Samsung. I would have expected some nameless Chinese company.
I have no knowledge or training with repairing CRT displays, so I'm comfortable with calling this unit pooched. Such a shame since it was mint in the box, and I only put a few hours on it. Thanks everyone for the help.
