5. Maintenance
5.1 Screen Cleaning
To clean the screen, first power off the TV and unplug it. Use the included screen cleaner and microfiber cloth. Spray the cleaner onto the cloth (not directly onto the screen) and gently wipe the screen in a circular motion until clean. Avoid using abrasive cleaners or cloths.
5.2 General Care
Keep the TV in a dry, well-ventilated area. Avoid exposing it to direct sunlight, extreme temperatures, or high humidity. Do not block ventilation openings. Regularly dust the TV cabinet with a soft, dry cloth.
6. Troubleshooting
If you encounter issues with your TV, please refer to the following common problems and solutions:
- No Power: Ensure the power cable is securely connected to both the TV and a working electrical outlet. Try plugging another device into the outlet to confirm it has power.
- No Picture/Sound: Check that the correct input source is selected (e.g., HDMI 1, TV). Verify all cables are securely connected. For no sound, check the TV's volume, mute status, and external audio system connections if applicable.
- Poor Picture Quality: Check the resolution of the input source. Ensure cables are not damaged. Adjust picture settings (brightness, contrast, sharpness) in the TV menu.
- Network Connection Issues: For Wi-Fi, ensure your router is on and within range. Re-enter the Wi-Fi password. For wired connections, ensure the Ethernet cable is securely connected to both the TV and router. Try restarting your router and modem.
- Remote Control Not Working: Check the batteries and replace them if necessary. Ensure there are no obstructions between the remote and the TV's IR sensor.
If the problem persists after trying these steps, you may need to perform a factory reset (refer to the TV's on-screen settings menu for this option) or contact customer support.
