Hello and thank you for providing such a great forum. Lots of useful information throughout the whole site.
I have found two other threads addressing this issue, but one is from 2014 and the other from 2016. I wasn't sure if it was proper to resurrect those threads, so here I am.
I have an SDM3055 stuck on the boot screen that is black with white writing "Siglent-Siglent Technologies."
The power turns on the fan and the DMM attempts to boot, but hangs on the boot screen.
I have downloaded the updated firmware, but I am unable to find instructions for updating without access to the display.
I have contacted support@siglent.com, per the instructions on their "After Sales" webpage.
While I was waiting for a response, I was hoping perhaps someone here may have a suggestion.
TIA for any replies and have a great day!
