Hey there fgswww(?),
Look at page 6-13 of the service manual, where it describes the "Kernel
Tests" and "Exerciser Routines". The front panel LEDs likely have a message
for you relating to the specific failure the MPU has detected.
If you can post a video of the front panel as the scope is powered on, we
could help decipher the message, and/or verify your decoding...

Hi, I m from Argentina. I m repairing a 2445B. When I turn on it, the
panel control lamps flashing one time only. The TRC never drawing anything.
I check the J119 voltages, for example....pin # 1. (-15V) I read -14,6V
(+/- 0.2V) pin #8 I read 82V (+/- 0.3V) etc etc etc. The readouts are
nearby but are not exactly.
