Doug is talking about this: "Troubleshooting your Oscilloscope". You should
read through this - it tells you how to use the scope itself to narrow the
problem down. I recommend it highly. It's designed for technicians to
narrow down Tektronix scope problems quickly through the front panel
controls. The only way to do that is to use the scope to debug itself
according to them.
I don't think you need the exact serial number for the 465B to use the
service manual - they are all pretty much the same.
Best,
John

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?
