Time to play: "Let's all try to guess the Model number."
What's a "deflectometer?"

The microprocessor in your set is NOT receiving confirmation that the TV has vertical deflection and is therefore shutting "of automatically."
You probably need to replace the vertical output IC, making sure that it still has power supply(ies) to it and also replace the electrolytics in the immediate area (especially the 100ufd - 220ufd / 35 volt - 50 volt).
