Checking Power and Connections

To diagnose and resolve no video issues on your workout TVs, the first step is to check the power and input on TVs. Make sure that the TV is turned on and receiving power. Confirm if the TVs are on HDMI 1 input source using your TV remote, this maybe on different input depending on your installer but usually HDMI 1 would be the obvious default input. If you have VGA cabling, this would be PC input or RGB input source on the TVs as your selection. This varies depending on your TVs and cabling. Additionally, check if there are any loose connections or damaged cables that may be causing the problem. By ensuring proper power supply and secure connections, you can eliminate potential issues related to power and connectivity.

Verifying Input Source Settings

In some cases, the no video problem may be due to incorrect input source settings on the TV. Verify that the TV is set to the correct input source, such as HDMI 1 or the corresponding input where the media player is connected. Use the TV's remote control to navigate through the input source options and select the appropriate one. Sometimes, the TV may automatically switch to a different input source if multiple devices are connected or when TVs are in a studio small space the TV remote signals may bounce and change settings on adjacent TVs. Try moving closer to the TV and adjusting witht the TV remote directly pointed at the TV's reomte reciever. By ensuring the correct input source is selected, you can resolve any issues related to the TV not receiving the video signal from the media player.

 

Checking your video splitter is working

If you can hear the SPTV workout program playing in the studio, then the issue likely does not lie with the SPTV player, as its audio output is successfully reaching the amplifiers. In this scenario, any challenges you face are probably related to the video distribution system, specifically the HDMI or VGA splitter that connects the SPTV player to the workout TVs.

Before proceeding, try turning off your video splitter, typically labeled as an HDMI or VGA splitter. If you're unsure where it is located, feel free to send a photo of your AV rack, shelf, or cupboard to support@wedooh.com.au for assistance. After powering off the splitter, wait for 1-5 minutes before turning it back on. Ensure that it is receiving power and that the lights are illuminated correctly. Some splitters may only have a power light, while others may indicate input and output lights, showing the signal flow from the source (SPTV player) to each workout TV connected to the splitter. As different models and setups vary, it's best to consult with your installer or supplier if necessary.

If the workout TVs power up successfully, it suggests that the issue may have been resolved. However, if the TVs still do not show any video, it could be due to a malfunction in the splitter or its power source. In such cases, it is recommended to have a technician on-site with the required parts to effectively address the video signal problem.

Another common issue with HDMI splitters is that some may not wake the TVs after an extended period when the actual TVs are turned off. This issue, related to video handshake/HDCP/EDID, requires your AV installer or supplier to either update the splitter's firmware or switch to alternative manufacturer's video distributors. The problem does not stem from your source (SPTV player) as the HDMI signal remains on continuously, even when the SPTV player is displaying a black signal after hours. When the TVs are turned off for prolonged periods, the signal is lost from the splitter to the TVs, not from the SPTV to the splitter. While this power-saving mode of the splitter may not be resolved, it is not an issue from the SPTV end.

If power cycling your splitter does not make any difference on your workout TVs, it is likely faulty, and you may need a replacement power supply or splitter (or both).

Resetting the Media Player

If the above steps do not resolve the no video problem, try rebooting the source media player. Locate the power button on the media player and press it ONCE ONLY to initiate a proper shutdown. Typically the shutdown process should take less than 30secs and the unit will power down automatically. This will restore the media player to its default startup operations. After it has powered down, wait for a few seconds and then turn on the media player and check the TV(s). Check if the video signal is now being displayed on the workout TVs. Restarting the media player can help re-establish the video signal flow through the video distributor, especially after performing the steps to power cycle the video splitter as mentioned earlier.

Inspecting HDMI or VGA Cables

After confirming that power and connections are functioning properly, the next step involves inspecting the HDMI or VGA cables. This task may vary in difficulty depending on the setup of each location, so it is advisable to have an on-site technician handle this step. These cables play a crucial role in transmitting the video signal from the media player to the TV screens. Ensure that the cables are securely plugged into the appropriate ports on both the media player and the TVs, taking into account any intermediary distribution devices. Look out for any visible signs of damage or twists in the cables that could potentially disrupt the video signal flow. If there are multiple TVs in use, it may also be necessary to examine the HDMI or VGA splitter, if one is being utilized. By carefully examining and troubleshooting the cables, any underlying issues causing the absence of video on the workout TVs can be identified and addressed.

Contacting Technical Support

If you have followed all the troubleshooting steps and the workout TVs still do not display any video, it is recommended to contact technical support. They can provide further assistance and guidance in resolving the issue. Make sure to provide them with detailed information about the problem, including the steps you have already taken to diagnose and troubleshoot. Technical support can assist in pinpointing any hardware or software issues related to the SPTV source media player or the TVs/video distributors.
