Yes, I did. All supplies are within the tolerances.

Have you checked all the power supply test points on the main interface board? Be sure to check the -8 volts.

My 465B does'nt show a trace. The trace seems to run outside the visible ara of the crt. There is a green light running over the screen. This light varies depending of the intensity and reacts on the horizontal an vertical position and the choosen timebase. The high voltage of the crt is 15kV, the voltage on the cathode is -2445V. All voltage on the crt are correct. The z-axis board works.
