Frequently Asked Questions - 21FB7AG LG
How do I connect an external device to my LG 21FB7AG TV?
Use the composite RCA inputs (yellow for video, red/white for audio) on the back of the TV. Ensure the TV is set to the correct AV input using the Input button on the remote or TV.
Why is there no picture but sound is present?
Check that the brightness and contrast are not set to minimum. If using an external source, verify the connection. If the problem persists, it may indicate a CRT failure requiring professional repair.
How can I clean the TV screen?
Unplug the TV. Use a soft, dry microfiber cloth to gently wipe the screen. Do not use water, alcohol, or abrasive cleaners, as they can damage the anti-glare coating.
Does the LG 21FB7AG support HD signals?
No, this is an analog CRT TV with a standard definition 4:3 aspect ratio. It cannot display HD signals natively. You would need an external converter to watch digital broadcasts.
How do I set the sleep timer?
Press the Sleep button on the remote repeatedly to cycle through time options (e.g., 30, 60, 90, 120 minutes). The TV will turn off automatically after the selected time.
What should I do if the TV turns off by itself?
First, check if the sleep timer is set. If not, it could be an overheating issue or a faulty power supply. Unplug the TV for a few minutes and try again. If it continues, consult a technician.
Can I mount this TV on a wall?
The LG 21FB7AG does not have VESA mounting holes and is designed to be placed on a stable tabletop with its built-in stand. Wall mounting is not recommended due to the CRT weight and structural limitations.
How do I perform a channel scan?
Press the Menu button, navigate to 'Channel' or 'Setup', select 'Auto Program' or 'Auto Scan', and confirm. The TV will search for available analog channels.
Where can I find the user manual?
The manual is available for free download in PDF format on the product page at notice-facile.com. It includes 20 pages of instructions in English.
Is the remote control included?
Yes, the LG remote control is typically included with the TV. If lost, you can use a universal remote compatible with LG TVs.
