Samsung tv not responding on ir-transmitter

Third party integrations

Hello,

I have collected the codes from the samsung remote trough an sipmle ir receiver.

I installed a nodemcu with the next code
HA:

script:
  tv_button_1:
    sequence:
      - service: esphome.nodemcu01_send_samsung_command
        data:
          data: 0xE0E020DF
          times: 10

ESPHOME:

api:
  services:
    - service: send_samsung_command
      variables:
        data: string
        times: int
      then:
        - remote_transmitter.transmit_samsung:
            data: !lambda 'return strtoul(data.c_str(), nullptr, 16);'
            repeat:
              times: !lambda 'return times;'

When I press the button in HA the red light on the transmitter goes on for a short time. Using the camera of a smartphone I see the ir-blueish light also.

The tv does not responde. Am I missing something? Or is maybe the simple ir-transmitter board (from banggood/aliexpress) to simple? An ir-colorbulb lamp with “nec”-code does respond, so the board is partial functioning.
