When I did the tube in my RCA I more or less did this procedure (killing the Beltron after a second of the lights lighting up) by accident, in that when I saw those light light up, I pulled the cable going to the CRT from the plug on the Beltron. I wasn't sure what the lights meant. And then set the heater back down, and did a test and the CRT was alive again. I read and reread the instructions (all 3 pages of it) but I must have missed it, the instructions saying to shut it down once the lights light up... This is my first CRT, so there is this learning curve...
