TVs LG with an operating system Android TV combine the convenience of smart functions with the classic TV experience, but sometimes users encounter a problem: the screen does not respond to the remote control, the indicator blinks or the device shows no signs of life at all. The reasons may be different - from a dead battery in the remote control to software failures after an update. In this article we will analyze all possible methods of inclusionincluding hidden functions and emergency methods that work even when the system freezes.

It is important to understand that the algorithm of actions depends on TV models (series OLED C2, NanoCell 86, QNED 90 i etc.), version Android TV (8.0–14) and type of problem. For example, for devices with ThinQ AI voice commands are available, and older models (before 2020) may require a mechanical reset. We have structured the instructions from simple to complex so that you can quickly find a solution without unnecessary manipulation.

If your TV LG does not turn on after a power surge, software update or long period of inactivity - do not panic. In 80% of cases, the problem is solved without calling a technician. The main thing is to follow the instructions consistently and not skip steps.

1. Checking the remote control and power source: basic steps

Start with the basics: often the reason lies not in the TV, but in the remote control or socket. Here's what you need to do first:

  • 🔋 Check the batteries in the remote: Even if the indicator on the remote is on, the batteries may be low. Try replacing them with new ones (we recommend Duracell or Energizer for stable operation).
  • 🔌 Make sure that the power cable is tightly inserted into the socket and connector POWER IN on the back panel of the TV. If you use a surge protector, connect the TV directly to the outlet.
  • 📺 Press the power button on the TV body (usually located under the logo LG or on the side). On models with OLED-screens, the button can be touch-sensitive.
  • 🔄 If the indicator on the TV flashes red, this is a sign standby mode. Press the power button on the remote control and hold it for 5-7 seconds.

If after these steps the TV does not turn on, proceed to the next step. Please note: on some models (for example LG G2), the power button on the case only works when the power is completely turned off (you need to remove the plug from the socket for 30 seconds).

⚠️ Attention: If the TV was connected via surge protector during a power surge, the power supply may be damaged. In this case, independent repair is not recommended - contact a service center.

2. Power reset: “hard” reboot

If the TV LG does not respond to the remote control and buttons, but the indicator is on or blinking - try hard reset. This method works in 60% of cases when the system freezes Android TV.

Instructions:

  1. Unplug the TV from the outlet (unplug the power cable).
  2. Hold the power button on the TV body 30 seconds (even if the TV is turned off). This will discharge the capacitors.
  3. Wait 2-3 minutes (important for models with OLEDscreens).
  4. Connect the power back and try to turn on the TV with the button on the case or the remote control.

On TVs LG 2021 and newer (for example, C1, G1) after such a reset it may start diagnostic mode - don’t be alarmed, this is normal. If the message appears on the screen Checking System, wait for the process to complete (up to 5 minutes).

☑️ Checklist for hard reset

Done: 0 / 4

If the reset did not help, and the indicator on the TV blinks red with pauses - this may indicate for a power supply or motherboard error. In this case:

  • Count the number of blinks in a row (for example, 3 blinks - pause - 3 blinks). This is error codewhich will help the technician diagnose the problem.
  • If there are more than 5 blinks, this is a critical error that requires repair.

3. Using the original remote control or LG ThinQ application

If the TV responds to the power button on the case, but does not turn on with the remote control, the problem may be pairing or a malfunction of the remote control. Here's what to do:

Method 1: Reconnecting the remote control

  1. Bring the remote control at a distance 10–15 cm to the IR receiver of the TV (usually located to the right or left of the logo LG).
  2. Press simultaneously the OK (central) and Back (back) buttons for 5 seconds.
  3. Wait for the indicator on the remote control to blink - this is a signal of success pairing.

Method 2: Control via smartphone

Download the official application LG ThinQ (available for Android and iOS) and connect to the TV via Wi-Fi:

  • 📱 Make sure that the phone and TV are connected to the same Wi-Fi network.
  • 🔍 In the application, click Add device → TV and follow the instructions.
  • 🎮 After connecting, you can turn on the TV with a virtual remote control in the application.
⚠️ Attention: On TVs LG 2020 and older (for example, UN7300) for operation ThinQ may be required firmware update. If the application does not find the TV, check the software version in the settings.
What to do if ThinQ does not connect?

If the application does not see the TV, try:

1. Reboot the router.

2. TV (you can find it in the network settings on the TV).

3. Disable VPN on your smartphone.

4. Reset the network settings on the TV (Settings → Network → Reset network).

4. Emergency switching on through the service menu (for experienced users)

If the TV LG does not turn on even after a power reset, but responds to the buttons (for example, the indicator lights up) - you can try to start it through service menu. This method is suitable for models on Android TV 9.0 and newer.

Instructions:

  1. Unplug the TV from the outlet.
  2. Hold the button Menu on the remote control (or the settings button on the case if the remote control does not work).
  3. Without releasing the button, connect the power back.
  4. Hold the button further 10–15 secondsuntil the service menu appears (usually a blue screen with white text).

In the service menu:

  • Select item Factory Reset (reset to factory settings) - this will help if the problem is a software failure.
  • Or select Power On (forced activation).

Important: Do not change other parameters in the service menu if you are not sure of their purpose. This may lead to irreversible consequences, including loss of warranty.

TV model Combination to enter the service menu Risks
OLED C1/C2/G2 Hold Menu + power Reset image settings
NanoCell 85/90 Hold Settings (on the body) + power Possible loss of application licenses
QNED 99 Hold Input + Volume Down Reset network settings
UK6200 and older Hold Menu 30 seconds after turning on Minimum (reset only)
💡

If after resetting the TV requires entering a PIN code, try the standard combinations: 0000, 1234 or 7777. On new models, the PIN may be indicated on a sticker on the back of the case.

5. Checking for hardware faults

If none of the software methods worked, the problem may be in hardware. Here's how to diagnose a malfunction:

  • 🔍 Power indicator:
    • ⚫ Off —no power (check the cable, socket, power supply).
    • 🔴 Lights red —TV in standby mode or the power supply is faulty.
    • 🔴⚪ Flashes red and white - motherboard or screen error.
  • 🔊 Sounds: If you hear clicks or squeaks when you turn on, this is a sign of a faulty power supply or backlight inverter (on LED-models).
  • 📺 Screen: If there is an image, but there is no backlight (dark screen with a barely visible picture) - the problem is LED backlight or the inverter.

Models with OLEDscreens (for example, LG C2) are characterized by the problem of “dead pixels” or panel burnout. If the screen turns on, but colored spots or stripes are visible on it, this is a sign degradation of the matrixand the panel needs to be replaced.

⚠️ Attention: If the TV emits humming sound or smells like burning, turn it off immediately offline! This is a sign of a short circuit and continued use is dangerous.
💡

If the TV does not turn on after a thunderstorm or power surge, do not try to repair it yourself. Contact a service center - there is a high risk of damage to other components.
