I’m also new to the forum, however long time viewer of Dave’s YouTube channels. I’m only a bit of a hobbyist & recently when I tried to use my Jaycar QC1934 oscilloscope I have also fallen victim to the “Stuck on Splash Screen” issue that has been discussed in this forum. I have never updated the firmware and seemed to work fine for the last 3 or 4 years.
I believe it is actually the siglent sds1102 cml plus, correct me if I’m wrong Ref attached photos. No relays click just splash screen, Repeatedly pressing math button doesn’t do anything. Just all buttons lit up and a led inside pulsing. It has a sd card slot, lan port, usb, bnc connector & an unpopulated J11 pads.
I have tried to contacting siglent for support, the American address info@siglent.com keeps bouncing back, no reply from the other 2 email addresses.
Any help would be greatly appreciated. TIA

Welcome to the forum.
Indeed it does seem like a SDS1102CML+ and info from here confirms it has 2Mpts mem depth as CML models do.

Send me a PM with your email address.

You're welcome D, enjoy.
This wasn't as straightforward as many as I suspect QC1934 firmware was some early version that didn't support USB recovery however the somewhat more involved MicroSD card recovery did the trick. :phew:

I have a Siglent 1102CML+ which is stuck on logo. I need some info from @tautech to help me restore it like so many other happy users here. Thank you.

Hello and good morning.. Where I teach we have a sds 1102cml+ oscilloscope that does not start and remains with the black screen of the logo. I would appreciate help to repair it, since the warranty date has passed. I have connected through the terminal and this is what appears:
