Siglent SDS1102CML+ non-responsive: Any ideas?
(1/6) > >>
dclaar:
I have a SDS1102CML+, about 3 years old. Hadn't used it in a while, and when I fired it up, it was non-responsive:
None of the buttons or knobs work.

I can connect via rs-232 and EasyScopeX, but none of the commands (e.g. *RST) do anything. Plugging in a USB drive gets a response on the screen that it was plugged in, but I can't do anything with it.

I tried the "hit the math button a bunch of times at boot", but--since none of the buttons work--nothing happened.
I contacted Siglent, and they sent me a zip file "System Recovery by U-disk", but the unit doesn't seem to see the USB drive until it is booted, and doesn't read the files. They said that I should just use a FAT-formatted USB drive, which I did.

Any ideas? At this point it is pretty much a paperweight. Siglent will take a look at this $300 scope for only $200 + S&H. :(

I've included a picture of what's on the screen after it boots.

Thanks! [ Attachment Invalid Or Does Not Exist ]

A few.

First the USB drive should be formatted as FAT32. Please confirm.

Do you have an activity LED in the USB drive in order to see this ?

Did you take note the recovery package instructions say not to use a 16GB stick ?

Do you have proof of purchase date for a possible warranty claim just in case USB recovery fails ?
dclaar:
I used a 1GB drive, FAT32 formatted. It has a little light on it (those are getting harder to find!), and that light starts blinking very late in the boot process, a split second before the "stuck display" image and USB drive recognition pop-up comes up.

I would expect it to hit the drive a lot earlier in the process if it were going to recover the unit, but that's just based on other small systems, not on any real-world experience with this unit.

As the unit was purchased in Dec 2016, it is a few months out of warranty. :(

OK good you've done everything correct.  :-+
I guess you tried more than once.

Send me the SN# via PM and I'll make some inquiries.
