If you're experiencing a strange HDMI issue with your Onn TV, there are several troubleshooting steps you can take to identify and potentially resolve the problem. Here's a step-by-step guide: Check HDMI Connections: Ensure that the HDMI cable is securely connected to both the TV and the source device (e.g., a computer, gaming console, or set-top box). Try using a different HDMI cable to rule out a cable issue. Verify Input Source: Make sure that the TV is set to the correct HDMI input source. Use the TV remote to navigate to the input/source menu and select the appropriate HDMI port. Power Cycle Devices: Turn off both the TV and the connected device. Unplug the power cables from both the TV and the device. Wait for a minute, then plug in the power cables and turn on the TV and device. Update Firmware/Software: Check if there are any available firmware or software updates for your Onn TV. Manufacturers often release updates to address bugs and improve compatibility. Try a Different HDMI Port: If your TV has multiple HDMI ports, try connecting the device to a different port to see if the issue persists. Test with Another Device: Connect the HDMI cable to a different device (e.g., a DVD player or another computer) to see if the problem is specific to the original device. Check Device Resolution Settings: Ensure that the resolution settings on your source device are compatible with the TV. If the device is set to an unsupported resolution, it may not display properly. Factory Reset: If the issue persists, you may consider performing a factory reset on the TV. Note that this will erase any custom settings, so make sure to back up any important configurations. Contact Onn Support: If none of the above steps resolves the issue, it's recommended to contact Onn customer support for assistance. They may provide specific guidance or recommend additional troubleshooting steps. Consider Professional Help: If the TV is still under warranty, and the issue persists, consider seeking assistance from a professional technician or the place of purchase. Remember to consult the user manual for your specific Onn TV model, as it may contain additional troubleshooting steps or model-specific information. If you provide more details about the nature of the issue, I may be able to offer more targeted advice.
