Troubleshooting FAQ
1. What can I do if there is no video output?
- Check if the “Link” and “Video” LED indicators are in normal status (solid on).
- Ensure the source device and the display device are powered on. And ensure the source device is outputting video signal while the correct HDMI input channel is selected on the display device.
- Try using shorter HDMI cables with better quality.
- Ensure all of your HDMI cables work normally. You can connect the source to the display device directly via one of these HDMI cables, to check if video can be shown normally on the display.
2. What can I do if HDMI ARC/eARC is not working?
- Check if the “Link” LED indicator is in normal status (solid on).
- Check if the “eARC” LED indicator is in normal status (solid on/blinking).
- Ensure the HDMI eARC/ARC ports of the AV receiver and the TV are connected correctly. The transmitter’s “HDMI IN” port should be connected to the AV receiver’s “HDMI eARC/ARC” output port, while the receiver’s “HDMI OUT” port should be connected to the TV’s “HDMI eARC/ARC” input port.
- Ensure the eARC/ARC and CEC functions of the AV receiver and the TV are enabled.
- For the AV receiver, you need to select “TV audio channel” to play eARC/ARC audio from the
- Try turning the TV off then on again, so eARC/ARC can re-handshake to establish connection.
- Ensure your HDMI cable work properly. You can connect the AV receiver to the TV directly via your HDMI cable to check if the eARC/ARC function works.
3. What can I do if the “Link” LED indicator is not solid on, blinking or off?
- It is recommended to use a Cat5E/6/6A/7 cable, instead of Cat5 or flat cable.
- Check if the total length of your cable is within 70m/230ft.
- Check if the connectors at both ends of the cable meet the IEEE T568B standard.
- Use a new cable, or try crimping your Cat cable connectors according to the IEEE T568B standard.
- If you need to use patch cables at both ends, the length should be as short as possible, no more than 5m/16ft. Please ensure all connectors meet the same standard (IEEE T568B). Please also note that the total length of the patch cables and the Cat cable should not be over 70m/230ft.
4. What can I do if the transmitter or receiver is not powered on?
- Check if you have plugged in the transmitter with the included power adapter. This HDMI extender supports one-way PoC, so the receiver can be powered by the transmitter.
- Check if the connectors at both ends of the cable meet the IEEE T568B standard.
5. What can I do if IR connection is not working?
- Check if your IR connection method is correct. The IR receiver cable needs to be connected to the “IR In” port at one end, and the IR emitter cable needs to be connected to the “IR Out” port at the other end. Please note that the 3.5mm cable connectors need to be fully inserted into the IR ports.
- Check if you use the remote controller correctly and if you place the IR emitter head correctly. When you use the remote controller, it needs to be directly facing the IR receiver head. Besides, the IR emitter head should be placed closely to the IR receiving window of the controlled device.
- Try controlling the source device directly via your remote controller, without using the HDMI extender. Then check if the IR connection works.
Other FAQ
1. What are HDMI ARC and eARC?
HDMI ARC and eARC are both features of HDMI. ARC stands for “audio return channel”. It allows a single HDMI connection to be used as both an input and an output, which eliminates the need to use a dedicated audio cable to connect a soundbar or AV receiver to your TV. HDMI ARC can provide a two-way flow of audio between your TV and audio system via just an HDMI cable. It can be one of the best home theater features, as it can reduce cable clutter, save more cost and simplify your home theater setup.
eARC stands for “enhanced audio return channel”. As its full name implies, it has made some improvements on ARC, able to stream more complex multichannel formats, like Dolby TrueHD and DTS:X.
To learn more, please refer to the blog: “What Are HDMI ARC and eARC? What’s the Difference?”
2. What are the main differences between HDMI ARC and HDMI eARC?
HDMI eARC is the next generation of ARC. Its main advantage lies in a big boost in bandwidth and speed, as it allows you to transmit higher-quality audio from your TV to a soundbar or AV receiver. With its 37Mb/s bandwidth, eARC can carry up to 32-channel audio, including 8 channels of 192 kHz and 24-bit uncompressed audio. It also supports modern advanced audio formats like DTS-HD Master Audio, DTS:X, Dolby TrueHD, and Dolby Atmos.
In comparison, HDMI ARC only supports up to 6-channel compressed audio and has a maximum bandwidth of 1Mb/second. It supports different audio formats like PCM (2 channel), Dolby Digital (up to 5.1 channel) and DTS Digital Surround (up to 5.1 channel).
