There is an old manual out there on the internet about how to troubleshoot Tek scopes.? A Google search should uncover it quickly.? I have used it to troubleshoot scopes and it is quite amazing how much information you can get about your problem without any test equipment at all.? Most of it is done from the front panel controls on the scope itself.? Good luck.

Subject: [TekScopes] 465B won't trigger
Have a 465B in pretty good shape.
I can get a trace and waveform on the display, but it doesn't seem to trigger. The waveform will just roll sideways.
I have a paper repair manual, although I need to check if the serial number range matches.
I haven't cracked the case yet. My first thought is to check the supply voltages. Although I should probably do a more thorough operational check which should isolate the problem.
I don't have any calibration equipment. Just a DMM and the built in calibrator on the front. So I'm not inclined to make any internal adjustments unless absolutely necessary.
Any thoughts where to start?
