Tektronix 2465B Error on turn-on

I have a Tektronix 2465B (400MHz) scope that I picked up from my company
that was getting rid of some old stuff.

When I turn the scope on, it gives me Test 05 Fail 42 error. I clear it by
hitting the trigger button I believe and I can start to use the scope. It
doesn't seem like anything is wrong, but then after a while the picture sort
of dissapears on me. If you move the position up and down you can sort of
see some blur of light, but if I shut it off for a little while and turn it
back on, it works again.

I haven't had much time to fool around with it and figure out just what's
going on so I could describe it better, but I was wondering if this alarm
had anything to do with my problem or are they two different problems?

If anyone knows what these codes are and/or how to fix the scope, please let
me know.

Thanks

Send it to Tek and ask for calibration. Send in all the probes as well.
They will tell you what it will cost.

My guess is, it is a power supply failure. Possibly focus voltage problem.

Hi there Dave,

I have the almost the same scope, the 2467B, and ive noticed that the Vertical section ( this is a Hybrid IC block) gets quite warm. my guess is its either a ( cooked ) HIC or that there are some voltages off in the power supply, that cause over heating and with that this failiure. the issue is, these IC's are hard to find, they are ceramic substrates with a dice and external components. anyways if you need one ill check it for you. i live in China and allot of these old scopes end up here.

Greetings!
