My regularly used HP 89411A DSA (rebadged 89410A) refused to start up today.
It is stuck on the bootup screen with all keyboard indicator lights off and no response to keypresses. HP-IB connection is dead too.
Restarting with "Return" pressed does not seem to make any difference.
Last time it powered up and worked just a few days ago fine.
Any idea what the next startup step would have been for a happy unit? Anybody had a similar issue?
Cheers
Leo
