    I'll try to get round to a mini road test of the DHO924 in a couple of weeks. MK

    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?

    Well, the display is working, at least for some time (Rigol logo can be seen in the video).
    I would say that there is faulty flash image or something similar, bad RAM or something similar. Boot sequence is able to display logo, but halt shortly after this.
    If the scope is new and under warranty, I would suggest to contact the vendor and ask for exchange.

    In the video, it doesn't seem to go black. It shows the Rigol logo till the end. And a healthy green power button LED.

    ahmedfotoh , how long did you leave it on?

    Get a photo of the error and contact the vendor. If it's new, don't try to reset anything yourself and use the warranty. Even if this is a hassle because being international.
