Bypass test fails Tek 2445?

[Steven Johnson]

I asked this on another group too with no response. Surely someone
here must be familiar with this. Please excuse me for trying again.

My Tektronix 2445 oscilloscope is showing two error codes on startup.
Without going into the specifics of each, can anyone tell me which
button(s) to push to bypass these and get the scope to operate?

I understand some of the affected functions may not work to
spec. I am hoping it is just calaibration faults and I can have a
usable scope until I have funds for repair.

Many thanks,

Steven Johnson

I don't know that scope but in most cases (my lab is mostly HP) a sudden
onset of error messages was remedied by re-seating EPROMs and other
chips in the affected instrument. They have often used expensive ceramic
parts but, for reasons that totally elude me, dirt cheap socket.

Press the A/B trigger button to override the eror mesage and try to get
teh scope to work.

For details on how to cure the sympthoms, check a service manual: The
errot code should be similar to "TEST xy failed ERROR nm" the xy and
nm usually give a pretty good hint where the problem is located.
