Check the power supply - is it providing the right voltage to the main controller card?

Was this the original power supply you received with the device? If not, have you looked at the manual/datasheet for the oscilloscope to see what voltage and amps it requires from the power supply?

Looks like they gave you a wrong one. This is shown in an unboxing blog:

I've seen 2 unboxings with that one

There may be different versions out there. Did the one you see, have a good enough clarity to read the current?

The author read them out and it was the same values as the label on the LiteOn one posted earlier (although it wasn't a LiteOn supply, I can't remember which now.)
