i'd try:
- update the bootloader. PI-imager, under utility images.
instructions: https://www.raspberrypi.com/documentati ... ate_stable
- if you remove the SD card, power up.... you should get diagnostic display.
- note that HDMI adapters are not good. most do not pass the EDID data back from the monitor, recommend an official cable.
- usually an adapter results in no display output. without EDID data, the PI doesn't know what resolution to set, and may set none... no display
- try burning a new copy of PI-OS using imager. (SD card supplied with "kits" are usually ancient....)
of course, all the above assumes what you got is a real PI.
