Buttons and knobs no respond on 2D10

Kjadr2

I have a similar problem. I have a DSO2D10 which is less than 3 months old. After not using it for a few weeks, I turned it on and it boots up, but none of the buttons work. The "CH2 MENU" button and "RUN/STOP" buttons are green and the rest are off. All of the buttons will beep, but nothing happens. Channel 2, which is lit, will not show a signal when a probe is connected to it.  HELP!!!

Please perform "FrontPanelSelfTest"(In Utility), better to give a video.

Since none of the buttons work, I can't access the Utility menu. Here is a link to a video of what is happening: https://1drv.ms/v/s!AsOCDTRBcITBh_pH7dHzKm1QCypYVA
