If your remote control is not working with your LG 55UK7700AUB, try the following troubleshooting steps:

• Check if anything, such as tape, has been placed over the receiver on the TV.

• Check if there is any obstacle between the TV and the remote control.

• Replace the batteries with new fresh ones.

If there is no image or sound on your LG 55UK7700AUB, perform these checks:

• Check if the product is turned on.

• Check if the power cord is securely connected to a wall outlet.

• Check if there is a problem in the wall outlet by connecting other products to it.

If your LG 55UK7700AUB turns off by itself, consider the following possibilities:

• Check the power control settings. The power supply may have been interrupted.

• Check if the auto-off function is activated in the settings menu.

• If there is no signal while the TV is on, the TV will turn off automatically after 15 minutes of inactivity.

• Cold Flicker: If the TV feels cold to the touch, there may be a small flicker when it is turned on. This is normal and not a malfunction.

• Pixel Defects: Some minute dot defects may be visible on the screen as tiny red, green, or blue spots. However, they have no adverse effect on the TV’s performance. The panel is an advanced product containing millions of pixels, and in a very few cases, you might see these deactivated pixels.

• Temporary Distortion: Avoid touching the LCD screen or holding your finger(s) against it for long periods. Doing so may produce temporary distortion effects on the screen.

• Image Sticking (Burn-in): Displaying a still image for a prolonged period may cause image sticking. Avoid displaying a fixed image on the TV screen for an extended length of time.

The sounds you may hear from your LG 55UK7700AUB are generally normal operational noises:

• Cracking noise: A cracking noise that occurs when watching or turning off the TV is generated by plastic thermal contraction due to temperature and humidity. This noise is common for products where thermal deformation is required.

• Electrical circuit humming/panel buzzing: A low-level noise is generated from a high-speed switching circuit, which supplies a large amount of current to operate the product. It varies depending on the product. This generated sound does not affect the performance and reliability of the TV.

The symbols found on your LG 55UK7700AUB represent the following:

• ☐ : Refers to class II equipment.

• ⏻ : Refers to stand-by.

• | : Refers to “ON” (power).

• ϟ : Refers to dangerous voltage.

You can connect an external control device like a computer or A/V control system to the RS-232C input jack to control the TV’s functions. The connection method depends on the port available on your TV.
