Deflection is required not just to produce meaningful test results, but also to distribute the energy dissipation due to electron bombardment evenly over the entire screen surface to prevent damage to the phosphor from overheating.

It must have been a bad day for posting. I know better. In retrospect I know you have to connect the deflection cable. Duh. Took a week of vacation and back now. Didn't realize how bad I needed that vacation.
