LG TV Error Code P08 — What It Means & How to Fix It

What Does This Error Mean?

P08 on an LG TV means the built-in Wi-Fi module is not being detected or is not responding. The TV cannot connect to any wireless network while this fault is active. You can use a wired Ethernet connection as a workaround while you troubleshoot or arrange a repair.

Affected Models

LG OLED C3
LG QNED85
LG UHD 75UP8770
LG NanoCell 90
LG OLED evo G3

Common Causes

Wi-Fi module has failed due to a hardware fault or manufacturing defect
Firmware bug has caused the TV to lose communication with the Wi-Fi chip
A software update has corrupted the Wi-Fi driver on the main board
Physical shock or heat has damaged the Wi-Fi module's antenna connection
A static discharge event has burned out the Wi-Fi chip

How to Fix It

Power cycle the TV by unplugging it from the wall for 60 seconds, then plugging it back in.

A power cycle resets the Wi-Fi module and can clear a P08 caused by a temporary firmware communication error.
If the TV powers on, go to Settings → Support → Software Update → Check for Updates.

A firmware update can restore proper communication between the main board and the Wi-Fi chip if a software bug caused P08.
Perform a factory reset: Settings → General → Reset to Initial Settings and enter your PIN (default: 0000).

A full factory reset reinstalls default firmware settings — this resolves P08 in cases where a corrupted driver is the cause.
Connect the TV to your router using an Ethernet cable as a temporary workaround.

Wired Ethernet bypasses the Wi-Fi module entirely and restores full Smart TV functionality while you address P08.
Check the TV warranty at lg.com/us/support using the serial number from the back label.

Wi-Fi module failures within warranty are covered — verify this before spending money on a repair.
Contact LG support at 1-800-243-0000 to report P08 and request a service assessment.

Technicians can confirm whether the Wi-Fi chip is at fault and advise on repair versus main board replacement.

When to Call a Professional

If a factory reset does not resolve P08, the Wi-Fi module or main board needs professional attention. Some LG models have the Wi-Fi chip soldered directly to the main board, making replacement the only option ($100–$300). In the meantime, a wired Ethernet connection or a USB Wi-Fi adapter (if supported by your model) keeps the TV functional.

Frequently Asked Questions

Can I still use my LG Smart TV if P08 disables the Wi-Fi?

Yes — connect the TV to your router with an Ethernet cable and all Smart TV features will work normally. If your TV does not have an Ethernet port, check if your model supports a USB Wi-Fi adapter. Streaming apps, LG Content Store, and software updates all work over wired Ethernet.

Why did P08 appear after a software update?

Software updates occasionally introduce driver bugs that break communication between the main board and the Wi-Fi module. LG typically releases a follow-up firmware patch within a few weeks when a known update causes Wi-Fi issues. Check lg.com/us/support for your model to see if a newer firmware version is available.

Does P08 mean I need to replace the entire main board?

Not necessarily — a factory reset resolves P08 in many cases where the Wi-Fi driver became corrupted. If that does not work, the Wi-Fi module itself may need replacing. On some LG models the Wi-Fi chip is a separate replaceable module — a technician can confirm which applies to your TV.
