Frequently Asked Questions - 21FL1RG LG
How do I connect my LG 21FL1RG to a cable box?
Connect the cable box's RF output to the antenna input on the TV using a coaxial cable. If your cable box has RCA output, use an RCA to coaxial adapter or connect directly to the AV input.
Can I use my LG 21FL1RG with a modern streaming device?
Yes, you can connect a streaming device (like Roku, Amazon Fire Stick) using an HDMI to AV (composite) converter, as this TV does not have HDMI inputs. Alternatively, use a VCR or DVD player with AV output.
Why is the picture distorted or rolling on my LG 21FL1RG?
This often occurs when the vertical hold or horizontal hold settings are misadjusted. Press the 'Menu' button, navigate to the picture settings, and adjust the vertical and horizontal hold. Also check that the antenna signal is strong and properly connected.
How to set up the teletext function?
Press the 'TXT' or 'Text' button on the remote control to activate teletext. Use the number keys to select a page, and the color buttons (red, green, yellow, blue) to navigate. Press 'TXT' again to exit.
What is the best picture mode for watching movies?
Select the 'Cinema' or 'Movie' mode from the picture presets. If not available, adjust the brightness, contrast, and color temperature manually to a warmer, softer setting to reduce eye strain during dark scenes.
The TV has no sound and no picture, what can I do?
Check if the power cord is properly plugged in and the wall socket works. Verify that the TV is powered on (power LED is lit). If the LED is lit but no audio/video, press the 'Source' button to cycle through inputs, and ensure the correct input is selected.
How do I clean the screen safely?
Turn off the TV and unplug it. Wait a few minutes for the tube to cool down. Use a soft, dry microfiber cloth to gently wipe the screen in a circular motion. Avoid using water or cleaning solutions, as they may damage the anti-glare coating.
Is this TV Energy Star certified?
CRT TVs typically have higher power consumption than modern flat screens. This model may not be Energy Star certified, but it meets basic standby power regulations of its time. Consider unplugging it when not in use to save energy.
Can I mount the LG 21FL1RG on a wall?
This TV is not designed for wall mounting. It has a heavy CRT tube and may lack VESA mounts. It is safer to place it on a sturdy, flat surface where it is stable and well-ventilated.
The remote control does not work, what should I check?
First, ensure the batteries are fresh and installed with correct polarity. Remove any obstacles between the remote and the TV's sensor window. If the remote has a protective film over the IR emitter, remove it. Also, check if the TV is in a 'Lock' mode (supervisor lock) from the menu.
