Agilent DSO9104A Scope stopped booting up. Advice On way forwards.
<< < (2/2)

Did you have any luck troubleshooting and repairing your DSO9104 oscilloscope?
It seems your 1.2v rail is problematic. Were you able to check the second sequencer? Maybe some type of failure between different stages of dc-dc conversion?
Thanks

The voltages from the accusation board looks fine, as far as I can tell.
I could not find any onboard fuses except one deep in the main power supply.

I'm thinking I'm going to have to bite the bullet and send it back to Keysight for a repair. $5300 qute.

Did they tell you what the issue is? I am considering buying one with a similar issue.

I'm afraid not.
It's just 'Repair by replacement'

Got it. Thanks for the reply. If I end up getting the unit and fixing it I will post here what I found.

Did you replace the whole unit or did you do a part replacement? If a part replacement what part?

Thanks
