7. Поиск Неисправностей
If you encounter issues with your llano HDMI 2.1 Switcher, refer to the following common troubleshooting steps:
- Нет видеовыхода/аудиовыхода:
- Убедитесь, что все кабели HDMI надежно подключены к обоим источникам сигнала, коммутатору и дисплею.
- Verify that the correct input source is selected on the switch (check LED indicators).
- Confirm that the switch is receiving power from the USB-C power cable and adapter.
- Test with different HDMI cables, especially high-quality HDMI 2.1 certified cables, as lower quality cables may not support high resolutions/refresh rates.
- Bypass the switch and connect the source device directly to the display to confirm the source device and display are functioning correctly.
- Flickering Screen or Intermittent Signal:
- This can often be caused by cable quality. Replace HDMI cables with certified HDMI 2.1 cables.
- Убедитесь, что электропитание стабильное и достаточное.
- Чтобы проверить, сохранится ли проблема, уменьшите разрешение или частоту обновления исходного устройства.
- IR Remote Control Not Responding:
- Проверьте и замените батарею в пульте дистанционного управления.
- Убедитесь, что между пультом ДУ и ИК-приемником на переключателе нет препятствий.
- Note that the effective range of the remote control may be limited.
- ARC (Audio Return Channel) Not Functioning:
- Confirm that both your TV and audio receiver are ARC-enabled and that ARC is activated in their respective settings.
- Ensure the HDMI cable is connected to the INPUT 4/ARC port on the switch and the designated ARC HDMI port on your TV.
- Some TV brands (e.g., Sony) may have specific ARC compatibility considerations with external switches. Consult your TV's manual.
- Automatic Switching (CEC) Issues:
