My SDS2104X plus, bought January 2021 does not start any more.
When pressing the power button at the front, the button lights up, but no fan, no screen, no further button lights.
Same after disconnecting all connection or trying different power cord, which are double checked and known good anyway.
Pressing lit button for some seconds makes it to unlight again.
I found the hint and pressed "Math" repeatedly during power on, but with no effect.

Yesterday it run as usual, normal power off and shut down.
Any ideas?
btw: Is someone knowing how to remove the „liberation“ licences from the device? I remember that there must be a SCPI command….
No, the new firmware is not the reason.
During fiddling with booting the device (with the "math" key trick) I mentioned that it was still on 1.3.5R5.
When I got it again up and running I just updated it to the last 1.3.9R12 - but it didn't boot again without the trick.
As we all suffer in Germany from the highest energy costs worldwide and the Siglents standby consumption is
to high all my devices are always hard switched off and the Siglent SDS and my SSA
are set to "Power on line enable".
Since I had the same problem with my SSA I start thinking that this could be the reason?
I alway shut down the devices with the power button (soft off), after that I disconnect it from mains. No hard switch off of course!

Worked for all the licences but not for the bandwidth. Any hint how to remove the bandwidth extension? Thanks in advance!!
Now I'm back with a virgin SDS2104X Plus.
But after several shutdowns and reboots the system does not hang anymore.....
I got a very fast reply from the Siglent service with a recovery file and I performed the
described procedure incl. update to the latest firmware (the recovery image is from 2020) but it still hangs.
Now the SDS is ready for DHL but in this minute I found in the SSA thread the hint that the SDS can hang when
you use an unusual attenuation factor in the channel menu.

I worked when the hanging starts with my LNA for some noise measurements and set the channel attenuation to 0.01 (40 dB) and 0.001 (60 dB).
Can someone check this? You always overcome hanging with repeatedly pressing „math“ during boot (3 times a second). But you must do a real shutdown and not a reboot to check it.
Now I unpacked my SDS from the prepared DHL parcel and checked it by myself again.
If I set attenuation CH1 to 1:1 system reboots after shutdown and disconnected from mains.
Reconnect to mains ("Power on line enable" active)
System boots.
Attenuation set to 1:100 (0.01), same procedure, system hangs.
SDS is production date April 2020. Latest firmware. HW 2.00
