content: Hi guys, I'm having a problem with the Siglent SDS1104X-E I bought recently. If I left it all night unplugged from mains, the next day, when I'm going to turn it on, sometimes it won't boot and stay stuck on Siglent logo. Only after 3-4 times trying to turn it on (with power button or connect disconnect from mains, doesn't matter which) I get a successful boot. I've tried upgrade/downgrade firmware but problem persists. I think I bought a lemon, or I'm doing something wrong?It's still stock, no bandwith or other hacks tried or done.Edit: Just to make things clear, I always turn it OFF using the power button, and some minutes after I turn off all mains.Thank you

content: My very early unit SN# 0014 gives no such issues .....ever.Install the latest V2 OS and firmware and monitor behavior.https://int.siglent.com/upload_file/zip/firmware/Oscilloscope/SDS1xx4X-E_OSV2_EN.ziphttps://int.siglent.com/upload_file/zip/firmware/Oscilloscope/SDS1xx4X-E_V6.1.37R6_EN.zipAre you using the lead supplied with it or another possibly faulty one ?Can you try it on another power socket ? .....we need to eliminate any other fault possibilities.We have sold lots of these and never any such problems.Inform your supplier and point them to this thread.DO NOT open the unit.

Not a power socket related, it doesn't matter what power socket I'm using. Return to factory defaults doesn't solve also. Since there's no reports of the same failure, I think I'm gonna pack the scope and return it. I decided to ask because could be something i'm not doing or some kind of settings, but I've already explore and carefully test all oscilloscope settings. This must definitely be a faulty unit.

content: We must be just lucky as never had a DOA unit.Our only warranty claims in a few years have been for a extremely noisy fan and a dud probe or 2 and a SDS1202X-E mainboard.....maybe we just don't sell enough units !

content: Interesting.Bit late reading this thread, but just a few days back, I had a similar situation. Plugged the scope to the mains, waited a short time then pressed the power button. Boot started, control buttons flashed through sequences, but then it hung up on the Siglent logo (white on black screen). A number of the control push buttons were lit, others not. Waited a few minutes with no further start-up progress.I thought it was just a random glitch -- it never happened before (have the scope for a year now) -- but reading this thread, maybe not . . .Not sure if I used the power button, or just pulled the plug, but when I started over, it booted up without fault.I recently installed the latest Firmware, and then V2 of the OS, but don't remember when the glitch happened in relation to the updates.@tautech Is the patch going to be a general update?
