Script does not work after update

Configuration
1

Hi,
after update to the latest version 0.96 a script does not work anymore.
here is the script.

dwdtvoff:
  sequence:
  - service: tts.google_translate_say
    data_template:
      message: Achtung! {{ states.sensor.dwd_weather_warnings_current_warning_level.attributes.warning_1_headline }}
  - delay: '00:00:05'
  - wait_template: "{{ is_state('media_player.kd_55xd8005', 'idle') }}"
  - service: media_player.turn_off
    entity_id: media_player.sony_bravia_tv

tts woks but than the tv doesn’t turn off.
before the update it woks fine.
One more thing.
I changed my  tv
the new one is found by home assistant but now is a problem with the old one.
in the frontend is a red box “no state available for (the old  tv)”
I already deleted it in the overview with all entities.
what can I do?
thanks for your help
