LG TV FP02 — What It Means & How to Fix It

What Does This Error Mean?

FP02 on an LG TV means the panel's power supply circuit has detected a fault. The power supply feeding the display panel is not delivering the correct voltage. This is a hardware fault requiring professional diagnosis — the power board or panel power circuit needs repair.

Affected Models

LG OLED C2
LG OLED C3
LG QNED85
LG NanoCell 75
LG UHD UP7670

Common Causes

Panel power supply board has failed or is delivering incorrect voltage
Capacitors on the power board have swollen or dried out
Loose or damaged power cable between the power board and the panel
Power surge has damaged the panel power supply circuit
Manufacturing defect in the power supply board

How to Fix It

Unplug the TV from the wall for 60 seconds to discharge the power supply, then plug it back in.

A brief power interruption occasionally clears transient voltage errors — though unlikely to fix FP02 permanently.
Plug the TV directly into a wall outlet — not through a power strip or extension lead.

Under-rated power strips can cause voltage drops that trigger panel power faults.
Check your TV's warranty status by visiting LG's website and entering your serial number.

Panel and power board faults are typically covered under LG's standard 1-year warranty.
Contact LG support at 1-800-243-0000 to report FP02 and arrange authorised service.

Provide your model number and serial number from the label on the back of the TV.
If the TV is out of warranty, get a repair estimate from an LG authorised service centre.

A power board replacement typically costs $100–$300 including labor — far less than a panel.
Ask the technician to specifically check the panel power cables and board connectors before replacing the full power board.

A loose power connector can cause FP02 and is a $0 fix if the board itself is undamaged.

When to Call a Professional

FP02 is a hardware fault that requires a qualified technician to diagnose and repair. Do not attempt to open the TV or replace components yourself — high-voltage capacitors inside TVs can be dangerous. Contact LG support to check warranty coverage before agreeing to any paid repairs.

Frequently Asked Questions

What is the difference between LG TV FP01 and FP02?

FP01 indicates a fault in the panel's display driver circuitry — the electronics that control the image. FP02 indicates a fault in the panel's power supply — the circuit that delivers voltage to the panel. Both require professional repair, but FP02 is sometimes cheaper to fix as it may only need a power board.

Can a power surge cause LG TV FP02?

Yes — power surges are a common cause of FP02 as they can damage power supply capacitors. Always use a quality surge protector (minimum 1000 joules) with your TV. If you had a storm or power outage before FP02 appeared, surge damage is the likely cause.

How much does it cost to fix LG TV FP02?

A power board replacement typically costs $100–$300 including labor. If the panel itself is damaged, costs rise significantly — panel replacements can cost $400–$800. Get a diagnosis first so you know exactly which component needs replacing before committing to repair costs.
