Wi-Fi module in LG TV: where it is, how to access it, and how to check its functionality

When the TV LG When a device stops connecting to Wi-Fi, many users immediately blame the router or network settings. However, the problem often lies in the hardware—a faulty or disconnected connection. Wi-Fi moduleTo diagnose or replace it, you need to know exactly where it is located inside the case. In this article, we'll look at how to locate the module in different TV series. LG (from budget UK62 to bonuses OLED C2), what tools will be needed for disassembly, and what to pay attention to when checking.

It's important to understand that TV designs have changed over the years: in older models (pre-2016), the module was often soldered onto the motherboard, while in newer models, it's a separate, removable board. We'll explore both options and offer troubleshooting tips without complete disassembly. If you've never disassembled a TV before, don't worry: the process is simpler than it seems if you follow the instructions and take proper precautions.

Why you might need access to the Wi-Fi module in your LG TV

Before you grab a screwdriver, make sure the problem is truly with the module. Here are typical symptoms of a faulty module:

• 🔌 The TV does not find any Wi-Fi networks, although other devices (smartphone, laptop) see them without problems.
• 📶 The network is available, but the connection keeps dropping or the internet speed is abnormally low (for example, 1 Mbps at the tariff 100 Mbps).
• 🔄 After updating the firmware, the "Wi-Fi" item disappeared from the settings menu.
• 💥 The TV is giving an error No network adapter or Wi-Fi module not detected.

Sometimes the problem stems from a software glitch—for example, after a failed software update. In this case, a factory reset will help.Settings → General → Reset). But if the reset doesn't help and the symptoms persist, it's most likely a hardware component that's to blame. Wi-Fi module may fail due to power surges, overheating or mechanical damage (for example, after a TV is dropped).

Where is the Wi-Fi module located in different series of LG TVs?

The location of the module depends on series And year of manufacture TV. Below we have provided a diagram for the most common models. Please note: in some cases, the module is integrated into the motherboard (especially in older or budget TVs), and replacing it will require soldering.

If your model is not in the table, use the year of manufacture as a reference:

• 📅 Until 2017: Most likely, the module is soldered to the motherboard. Look for it near the connectors. HDMI or USB - this is a small microcircuit with markings BCM43xx or RTL8xxx.
• 📅 2018–2023: the module is designed as a separate format board M.2 or mPCIe, usually covered with a metal screen.

How to disassemble an LG TV to access the Wi-Fi module

Disassembling a TV requires precision and a minimal set of tools. You will need:

• ⚒️ Phillips screwdriver (usually PH2)
• 🔧 Plastic pick or guitar pick (for releasing the latches)
• 📸 A phone for photographing the process
• 🧲 Magnetic backing or screw box

Step-by-step instructions (using an example) LG UK62):

Unplug the TV and wait until it cools down completely.

Place the TV screen down on a soft surface (towel, cardboard)

Remove the stand (if it is removable)

Prepare a well-lit work area-->

1. Remove the back cover. It's secured with latches around the perimeter and 4-6 screws (usually in the corners). Gently pry the cover up with a pick, starting at one corner and working your way around until all the latches are released.

2. Disconnect the antenna cables from the Wi-Fi module. They are usually connected to the connectors U.FL or IPEX (small white or black connectors). Pull the plastic connector, not the wires!

3. If the module is covered with a metal screen, unscrew it (usually 2-4 screws). In models OLED You may need to remove the heatsink from the processor (be careful with thermal paste!).

4. Unscrew the screws securing the module itself (usually 1-2 screws) and carefully remove it from the connector M.2 or mPCIe.

In models with a soldered module (for example, LH60) Disassembling is more complicated: you'll need a soldering station and experience working with microchips. If you're unsure of your skills, it's best to contact a service center.

How to check the functionality of the LG Wi-Fi module

Before buying a new module, make sure the old one is truly faulty. Here are a few diagnostic methods:

• 🔍 External examination: Inspect the module for blackened components, bulging capacitors, or signs of oxidation. If there is physical damage, the module must be replaced.
• 🔌 Checking the connection: Make sure the antenna cables are securely seated in the connectors. Try reconnecting them (sometimes cleaning the contacts with alcohol helps).
• 💻 Test on another deviceIf you have a spare module (for example, from an old laptop), plug it into the TV and see if Wi-Fi works. Make sure the connectors are compatible!

For deep diagnostics you can use service menu TV. To enter it:

1. Turn off the TV.
2. On the remote control, press and hold the button Menu (or Settings on new remotes).
3. Without releasing the button, turn on the TV using the power button.
4. After 5-10 seconds the service menu will appear (on some models you will need to enter a code - usually 0000 or 1111).

In the service menu, go to the section Network or Wi-Fi TestIf the module is not detected, you will see an error No Device or Fail. In models LG OLED 2022–2023 The service menu may block access to Wi-Fi tests—in this case, only a hardware test will help.
