content: Hello everyone.I own a Siglent SDS1104x-e which has been working ok for 3 years, bought it new.Today, suddenly, it stopped working. It's stuck at the booting routine, here's what it does:- Fan turns on- Power button turns on- Internal relay turning on and off- screen shows nothing- Rest of the buttons lights onAlready solved, here's the solution:The firmware was never updated. So this is most probably an old firmware bug.I had to start the scope with both channel 1 and channel 2 probes connected to the cal pin. This way for some reason started.After that , updated to the newest firmware available and problem solved.If any of you guys is thinking on buying a siglent scope, update the firmware as soon as new ver. are available

content: Quote from: little_carlos on March 23, 2022, 03:13:42 pmSometimes Math doesn't work first time and it normally pays to try it a few times as it's the normal fix for a boot freeze however Siglent do have a USB recovery package for theses scopes when Math doesn't work.

content: I have the same issue here. The USB recovery package - is it downloadable directly, or do we have to contact Siglent? I have tried a blank USB stick with the firmware on it, but it's still stuck at the 'Siglent' boot image, no matter what I try...

content: Thanks for the reply!Yeah - I've tried it numerous times, with no luck. It's a complete PITA, as I have a number of repairs piling up. Short of buying a new scope, is there anything else I can try?

content: Quote from: tautech on March 23, 2022, 07:09:22 pmCan you download the recovery files so you already have them ready just in case, or is it something you have to request from Siglent?I don't think I've ever had a boot freeze on any of my Siglent gear, but once and a while 1 of my scopes might stop responding, and I just reboot, some of that was probably me turning the knobs to fast, etc. I've updated all the firmware this year.
