So, after some digging the display shows the result!!
At first, Freenove sent me a Schematic of the Mini TV, so i could extract the right pinout.
After that i had to set the pin vor VDD to high on boot and this is the resulting yaml:
substitutions:
device_name: "freenove-esp32-mini-tv"
esphome:
name: ${device_name}
friendly_name: "Freenove ESP32 Mini TV"
on_boot:
- priority: 200
then:
- output.turn_on: output_vdd
esp32:
