That's what I've done today, the chassis is pulled and I am still getting no HV at the 3a3 hv terminal (grounded screwdriver) with all the tubes now in it and tested. I did not notice any popping or blue glow on the crt but then I was only looking at the screen when it happened, and didn't see anything there. Didn't see it when I had the back pulled either, all 3 guns were lit normally. It was pretty loud so I assumed it was an external pop and didn't see anything on the screen whatsoever either. Perhaps testing the crt with my crt tester would be in order. But I still have no hv period so I kind of assume the chassis problem is all I have and did not involve the crt. Would good readings on the crt test pretty much rule out damage? I forgot I do have a HV probe in the closet so I will see if I can remember how to hook it up and maybe make some measurements on the chassis. I do get a teeny tiny spark when I physically touch the screwdriver to the terminal, so there is SOME voltage on the 3a3 terminal at least, not nothing. Flyback looks great and I can't see where anything 'popped' anywhere else. Frenchy
