How do YOU work on a G07 in a Tron?

OK – I know that's a weird random question. Here is what I mean:

My Tron monitor died a couple weeks ago. I had it on for a few hours, came out and the screen was black, no neck glow. I pulled the chassis out and the flyback had a big black smoke mark on it. Without doing any real testing, I replaced it with a new flyback from Bob and hooked everything back up. Still a completely black screen, no neck glow.

I don't really have a workshop and have very limited knowledge about working on these monitors. I've capped all of my monitors, but that is about the extent of what I know how to do. I always pull the chassis off the monitor, leaving the tube mounted in the cab, set it on the dining room table and do my work.

So now I need to do some additional troubleshooting. I have the Fromme G07 flow-chart…but now finally my actual question:

How do I you guys do the testing? I'm assuming that to test various components you need to have the monitor all hooked up. Do you leave it in the cab and poke around with your meter? Do you pull the entire monitor and test outside of the cab? I know many of the folks here are pros at working on these.

I appreciate any tips or suggestions. I'd like to rule out anything easy, then I might ask to swap my chassis + $$ for a working one. I'm sure mine just has a "loose connection".

Thanks folks.
 
If so, discharge the filter cap before working on it.

As for testing, I have a spare tube with yoke on a shelf in the garage and use that for testing. If I'm doing voltage checks (besides B+) I do it on the bench without the tube. I hook up a spare yoke (set to the side) for a load, stick the anode cup into a glass jar (for safety), hook up power thru an iso, and test/repair until the B+ is proper. Sometimes I run into an issue where it needs the degaussing plug connected, too
 
I usually have a game that I can set the monitor behind and hook it up to test. Sometimes I have to put the monitor on something to get it up high enough to connect wires but I am working on getting a test bench set up.
 
I'm a lagger at checking in here, but I really do appreciate the responses and guidance folks. I'm going to try some of the suggestions here.

This is what I was thinking..I may try this, set up a table right behind the cabinet so I can work on the chassis, but leave the tube in the game.



Again, much appreciated.
