Setup Instructions
Follow these steps for proper installation of your KANTUTOE TV LED Backlight:
- Clean the Surface: Ensure the back of your TV is clean, dry, and free of dust or debris. A clean surface ensures optimal adhesion of the light strip.
- Measure TV Size: Determine the appropriate length and layout for your TV. The 9.84ft strip is suitable for 32"-45" TVs. For larger TVs, consider a U-shape or horseshoe application if the strip length is insufficient for all four sides.
- Peel and Stick: Carefully peel off the adhesive backing from the LED light strip. Begin applying the strip from a corner of the TV, pressing firmly along the edges. Use the included clips for additional security if needed.
- Mount the Light Strip: Mount the TV LED backlight around the back of your TV. Ensure the strip is positioned evenly and securely. The mini receiver should be positioned where it can be easily concealed behind the TV but still receive signals from the remote.
- Connect to Power: Plug the USB connector of the LED backlight into a powered USB port on your TV. If your TV does not have a USB port, you can use a standard USB wall adapter or a power bank (see Figure 5).
