I think I finally fixed it. My DP832 is now running without reboot for more than 24h.

Great work! I do not experience the reboots (yet?) of both of my DP832s, but it is good to know there is a solution when it happens. How old is your DP832? I wonder if this problem is related to a certain batch of instruments...

I bought my DP832 in Sept 2014. It already had the Rev 2.1 TobBoard with the large heatsink. FrontBoard is V2.0 (with a 2012-12 revision date).

By the way, still running without issue (48h now).

T2:
Just a heads up: My DP832 is not running for 2 months with this fix and has not experienced any issue (= reboot) since.
This modification definitively fixes the reboot issue.

All,

I came into possession of one of these units this week which has the constant reboot symptom described above.  The unit never manages to stay up longer than a few seconds, if that.  I intend on performing a modification to 4p2 V rail on the unit as T2 has described.  For reference this unit has the silver heatsink.  Screenshots below are documenting the performance on the LM317T regulator input and output as well as 4.2 V rail.

Once I perform the modification I'll advise on the performance, hopefully with screenshots.

This fixed the reboot (resetting the output to off, not a whole machine reboot)  issue for me as wel. Have mine DP832A  since mid-2014. Started having random reboots a few years ago (once every few days). It would never stay up for a whole weekend and now it's already is running for 2 weeks.

Thanks.

All,

Adding ceramic class 1 and class 2 capacitors as alluded to above seems to have solved the problem on my unit.  I will advise if it eventually fails.
