Dji smart controller black screen without overlay

[Noter]

Hello, after turn on my smart controller screen goes black .
Solutions with reboot doesn't work and I don't know what to do. SC even can't connect to drone.

Is battery fully charged? If not, try plugging in charger, wait 10 minutes and while charger is still plugged in, turn on smart controller again.

I already full charged a battery and no, controller does not show image.

I suppose that hdmi translation may somehow affect on SC. Can it be like that?
