Rigol DP832 Not starting up
« on: March 22, 2019, 12:17:41 pm »
My 5 year old Rigol DP832 was working correctly despite the occasional resets.
However, tonight it reset and never started up again.
The output wasn't connected to anything when it reset.
The display backlight is off and doesn't beep on startup or respond to any keys.
The cooling fan runs at low speed, so there is power to the unit.

Does anyone have any ideas?

Does your unit have the original "hot" regulator issue (see the old thread if you're not sure)? Perhaps it burned itself out, and since it powers the CPU section, it won't boot up.
There are also a bunch of through hole fuses on the PSU board, I would go through and test those. Along with usual voltage testing.
