Hello Forum.
I have a Tektronix 465 which I want to fix. I have been using it almost daily since 1998. Several weeks ago I powered it on and the vertical deflection was gone. If I press the beam finder, a horizontal trace will appear on screen, about a quarter inch above center. The up-down adjustment will not bring that trace into the visible area of the screen.
Any advice that would help in diagnosing and repairing this problem would be appreciated very much. Thanks in advance.
