1) get the official power supply.
2) since the eeprom reflash resulted in a green screen, your video output is assumed to be ok. but....
- remove the SD card, power up. you should get the diagnostic screen as shown below
pay attention to the last line as shown above ..... EDID OK
that means the EDID data from the monitor is ok. if your says "none" then your monitor did not respond to a EDID request from the pi. this means the PI does not know what resolutions are supported by the monitor, so it sets none. thus, no display.
you can force a resolution:
Set resolution manually: (under KMS driver only)
in /boot/cmdline.txt (add to the front/end of the line, NOT a new line)
-- IMPORTANT NOTE: for Bookworm, the file is at /boot/firmware/cmdline.txt !!
video=HDMI-A-1:1024x768@60D
(or whatever resolution you want)
