Hello all,
I have a Tektronix 465B analog oscilloscope. It was working without any problems but suddenly a problem with the trace has started. Now the trace doesn't appear on the whole screen. As you can see from the attached picture, the trace only appears on the left portion of the screen. This is true for both channels. "Position" knob adjusts the trace partially. So when I rotate the knob fully clockwise the trace disappears at the left and when I do the opposite the trace's maximum position is as seen in the picture. What can be the problem? What should I check? I have the service manual but I need a hint to find a start point. Any help is much appreciated.
Thank you
