Re: Tek 465 o'scope - no display

Thanks. I admit I'm a beginner with scopes, and I've been trying to
follow the manual for obtaining a basic normal display. The specs say
the AC input voltage is way over the 120V outlet, and I figured the
impedance of the scope inputs should keep the current down to a safe
level... guess not?

I'm in one of those situations where I don't have a known periodic
signal except for a wall outlet. I bought this scope to do automotive
diagnosis (oxygen sensors, fuel injectors, etc... NOT the high tension
side of the ignition... I know...) Maybe I ought to just start using
it that way. It doesn't make sense to me that beamfinder shows a trace
but nothing shows up otherwise. If it shows up with beamfinder, it
seems adjusting the scale controls (V/div and time scale) should at
least show something from the calibrator. I couldn't seem to get
anything from the calibrator even though there's something there when
beamfinder is pressed (this goes for both channels.)

I know, one person's issue isn't necessarily mine as well. Figuring
that this scope is over 1/4 century old with countless numbers of them
out there, I was wondering if possibly this is a known, common problem
that has a known fix (assuming it is a problem to begin with.)

Thanks for the input....
