Hello,   I'm having issues with my Orange Pi 4 LTS. I cannot get any HDMI output at the moment. Neither with the Debian flashed on the eMMC, or with Armbian running of the SD card.   In both cases I can SSH into the Orange and run commands normally.   The HDMI worked just a day before, but in the meantime I was flashing different systems and it stopped working. I tried different monitors and cables.   Any ideas what can I do?
