Ensure that the HDMI cables connected to the transmitter (TX) and receiver (RX) are secure and within the recommended length (usually under 5m). Verify that the network cable (Cat6/6A/7) or fiber optic cable linking the units is functioning and meets the bandwidth requirements.
Most transmitter modules, such as HDMI extenders or access control readers, have a small 'Reset' button. Press and hold this button for 5-10 seconds while the device is powered on to restore factory settings and re-establish connections.
A blinking status light typically indicates that the device has power but has not established a stable link with its receiver. On HDMI extenders, this may mean no video signal is detected or the network link is unstable. Consult your specific model's manual for detailed LED codes.
