Disconnect the lead from the flyback to the splitter. Place the flyback lead securely in a dry glass container and try to power up the set. If it doesnt shutdown the HV Block (splitter) is bad.

If you see the flyback. That has a large red wire resembling a sparkplug wire. That wire goes into the splitter. There will be 3 more red wires coming from the splitter going to the CRTs. Just take the one wire that goes from the flyback and place that in the glass jar. Now some models have the splitter built into the flyback if thats your vase scenario you will need to replace the flyback. No way to test that properly unless you have a ringer to test it with. let me know how you make out.

Failure of the HV splitter was a very common problem when I was doing these big screens on the road. The set won't come on if the splitter shorts. We used to test if that was the cause by pulling the HV input lead out of the splitter (leaving it still inside the plastic cup so it wouldn't arc anywhere) and turning the set on. Most often the set would fire right up (without picture of course).
I believe the RCA part number for the splitter is 205064, and it's available from a number of sources. I'm not home right now so I can't check. If I have the number wrong I'll post a follow-up comment.
