Modern TV is quite a complex device, but, nevertheless, the manufacturer tries as much as possible to make the TV control accessible. But if something happened to your TV, do not panic, try to figure out the causes of the malfunction. As a rule, troubleshooting can be very simple and does not require special knowledge and skills.
Cannot control the TV with the remote control
- Check the remote control sensor on the remote control and try again. If you are using an infrared remote, check if the LED blinks when you press the buttons, but do it with your phone camera. This is the only way to see the glow.
- Check for obstructions between the product and the remote. On televisions, the signal reception sensor is usually located next to the LG logo. If you are using the Magic remote, check for a source of interference near the TV, a WiFi router or other device with an active transmitter can cause interference. Try to place it as far away from the TV as possible.
- Check that the batteries are working and properly inserted. Tip The batteries are inserted with the flat end on the spring, this is a minus.
Picture is not displayed, sound is not played
- Make sure there is electricity in your home.
- Make sure the device is turned on.
- Make sure that the power cord is plugged into an outlet.
- Check if there is a problem with the outlet by plugging other devices into it.
Try turning the TV off and on, see if the power light comes on, if so, turn the TV on, if it does not turn on with the remote, try turning it on with the controls on the TV, usually a joystick-like button on the bottom next to the logo on the right or left.
The TV turns off suddenly
Check the power management settings. The power may have been turned off by the operating system. If you can turn on the TV with the remote control and it still works, then some power management setting is on.
- Check to see if the auto power off setting is turned on in the time related settings. If you do not use the TV for 3 hours, for example, the screen will alert you to go into sleep mode and prompt you to press any button on the remote control, if you do not, the TV will go into standby mode.
- If there is no signal when you turn on the TV, the TV will automatically turn off after 15 minutes of inactivity. Check the TV settings. If the TV turns on and off by itself, it is probably a technical problem and needs to be repaired.
When connected to a PC (HDMI), no signal is detected
- Turn off/on the TV with the remote control.
- Reconnect the HDMI cable
- Restart the device you are connecting to the TV, the TV must be switched on and the correct HDMI input must be selected.
Problems with the display
- If the device is cold to the touch, you may notice a slight “flicker” when you turn it on. This is normal, there is nothing wrong with the TV. This is more typical for LED panels, but OLED panels can also have this peculiarity. The reason for the flicker is that the display has not entered the operating mode.
- OLED and LED panels are modern products that contain millions of pixels. You may see tiny black dots and/or bright colored dots (red, blue or green) as small as 1 ppm on the panel. This does not indicate a malfunction and does not affect the performance or reliability of the product. This phenomenon is also found in third-party products and is not exchangeable or returnable. You should be aware that defective pixels may be present in the display. In LED panels, these are pixels that have stopped rotating, and in OLED displays, they are usually pixels that have stopped emitting light. Given the millions of pixels on a panel, a small number of defective pixels is not a malfunction.
- You may find a different brightness and color of the panel depending on the viewing position (left/right/top/bottom. down).
This phenomenon is due to the nature of the panel. It is not related to the operation of the unit and is not a malfunction.
- Displaying a still image for an extended period of time may cause the image to stick. Avoid displaying a still picture on the TV screen for a long period of time.
Problems with sound
- Crackling noise The crackling noise that occurs when watching or turning off the TV is caused by the thermal compression of the plastic due to temperature and humidity. This noise is characteristic of products that require thermal deformation.
- Electrical Circuit Rumble/Panel Rumble The low noise level is due to the high-speed switching circuitry that supplies a large amount of current to operate the product. It varies from product to product. This generated noise does not affect the performance or reliability of the product.
Abnormal noise may occur in the speakers if there is a WiFi-enabled wireless device nearby. If you are using the product to receive streaming services, try moving the product to a different location.
If there is a constant hum coming from the speakers, it is a malfunction. It usually occurs after several years of use, but is extremely rare in modern televisions.
