Troubleshooting
If you encounter issues with your SANSUI TV, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| No Power | Ensure the power cable is securely connected to the TV and a working power outlet. Try a different outlet. |
| No Picture / Black Screen | Check the selected input source (HDMI, AV, etc.) matches your connected device. Ensure the device is powered on. Try restarting the TV. |
| No Sound | Check the volume level and ensure the TV is not muted. Verify external audio devices (soundbar, headphones) are properly connected and powered on. Check sound output settings. |
| Remote Control Not Responding | Replace the batteries in the remote control. Ensure there are no obstructions between the remote and the TV's IR sensor. If using a universal remote, ensure it is programmed correctly for SANSUI TVs. |
| Slow Performance / Lagging Menus | Close unused applications running in the background. Disconnect from the internet and reconnect. Perform a factory reset if the issue persists (Note: this will erase all settings and installed apps). |
| Wi-Fi Connection Issues | Ensure your Wi-Fi router is on and functioning. Restart your router and the TV. Check Wi-Fi password. Try connecting via Ethernet cable if possible. |
| Interference with other TVs (e.g., LG) | This can occur due to overlapping IR signals or shared network protocols. Try repositioning the TVs or using a universal remote that can be programmed specifically for each TV. Check if there are settings on either TV to disable shared control features. |
