3. Setup
Physical Installation

- Identify the left and right stand legs. The legs are robust and designed for stability.
- Align each stand leg with the corresponding screw holes on the bottom of the TV.
- Secure the legs using the provided screws. Ensure they are tightened firmly.

Initial Setup (Roku OS)
Once powered on, the TV will guide you through the initial setup process for the Roku OS. This includes selecting your language, connecting to the internet (wired or wireless), and activating your TV. The activation process may involve downloading software updates and channels, which can take several minutes.
To activate your TV, you will typically need to visit roku.com/link on a computer or mobile device and enter a code displayed on your TV screen. Roku does not charge for activation or support.
4. Operating Your TV
Roku OS Navigation
The Roku OS provides a user-friendly interface for accessing streaming channels, live TV, and connected devices. Use the directional pad on your remote to navigate through menus and select options. The Home screen displays your installed streaming channels and inputs.
Picture Settings
To adjust picture settings for optimal viewing, it is recommended to do so while playing content from the specific input or streaming app you wish to adjust. Press the Asterisk (*) button on your remote to access the Options menu. From here, you can modify settings such as:
- TV Brightness: Adjusts the overall display brightness (Brighter, Bright, Normal, Dark, Darker).
- Picture Mode: Select from various presets (e.g., Dark HDR, Normal HDR, Bright HDR for HDR content; Movie for non-HDR content).
- Advanced Picture Settings: Provides granular control over Local Contrast, Dynamic Contrast, Backlight, Brightness, Contrast, Sharpness, Color, Tint, Color Temperature, Action Smoothing, Action Clarity, and LED Motion Clarity.
For HDR content, the TV automatically selects an HDR picture mode. For standard content, 'Movie' mode is often recommended for a balanced picture. Action Smoothing, Action Clarity, and LED Motion Clarity are typically turned off by default to prevent the 'soap opera effect' and motion blur.
5. Maintenance
Cleaning Your TV
Always unplug the TV before cleaning. Use a soft, dry cloth to clean the screen and cabinet. Do not use liquid cleaners, aerosol cleaners, or harsh chemicals, as they may damage the TV.
Software Updates
Your TCL Roku TV will automatically check for and install software updates when connected to the internet. Ensure your TV remains connected to the internet to receive the latest features and performance improvements.
6. Troubleshooting
If you encounter issues with your TV, try the following basic troubleshooting steps:
- No Power: Ensure the power cable is securely plugged into both the TV and a working electrical outlet.
- No Picture/Signal: Verify that the correct input source is selected. Check all cable connections between the TV and external devices. Ensure external devices are powered on.
- Poor Picture Quality: Adjust picture settings (refer to Section 4). Check the quality of the source content.
- No Sound: Check the TV volume and ensure it's not muted. Verify audio cable connections for external sound systems.
- Remote Not Responding: Replace the remote batteries. Ensure there are no obstructions between the remote and the TV's IR sensor.
- Network Connection Issues: Check your Wi-Fi router and internet connection. You may need to restart your router or re-enter your Wi-Fi password on the TV.
