LG TV P01 — What It Means & How to Fix It

What Does This Error Mean?

P01 on an LG TV indicates a power supply error — the power board is not delivering the correct voltages to the TV's internal components. The TV may not turn on, or it may power on briefly and then shut off. This is a hardware fault that usually requires power board replacement by a technician.

Affected Models

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

Common Causes

Power supply board has failed or has blown capacitors
Power surge or voltage spike has damaged the power board
Internal fuse on the power board has blown
Power cable is damaged or the wall outlet is delivering incorrect voltage
Main board is drawing too much current, causing the power board to fault

How to Fix It

Unplug the TV from the wall completely and wait 60 seconds for the capacitors to discharge.

A full power drain occasionally clears a transient P01 error caused by a brief voltage spike.
Plug the TV directly into a wall outlet — not through a power strip or surge protector.

Under-rated power strips can restrict current draw and trigger P01 during high-demand moments.
Test the wall outlet with another device to confirm it is delivering power.

A tripped circuit breaker or dead outlet is easily overlooked but can mimic a P01 fault.
Check for a standby LED light on the TV — if no light appears, the power board is likely completely dead.

A lit standby LED with P01 means the board is partially working — diagnosis is needed to identify the faulty rail.
Check your warranty status on LG's website using your model and serial number.

Power board faults are covered under LG's standard warranty.
Contact LG support or an authorised service centre to arrange a repair.

Power board replacement typically costs $100–$250 including labor at an authorised centre.

When to Call a Professional

P01 is a critical power hardware fault — do not attempt to open the TV yourself due to high-voltage capacitors inside. Contact LG support to verify warranty coverage before arranging any paid repairs. An authorised LG technician can safely test voltage rails and identify the faulty component.

Frequently Asked Questions

Can P01 on an LG TV fix itself?

If the error was caused by a brief power spike, a power cycle may clear it. However, if a capacitor or fuse has physically failed, P01 will not resolve without a repair. If the TV powers back on after a power cycle and runs stably, monitor it — if P01 returns, schedule a repair.

Is P01 on LG TV covered under warranty?

Yes — power supply faults are hardware defects covered by LG's standard 1-year warranty. Contact LG support with your serial number to arrange an authorised repair at no cost. Extended warranties and LG's ThinQ service plans may provide additional coverage beyond 1 year.

How do I know if it is P01 (power board) or a different fault?

P01 typically shows as the TV not turning on at all, or shutting off shortly after startup. If the TV displays a picture but then shuts off, a power board voltage fault is likely. A technician uses a multimeter to test the power board output rails and identify exactly which component failed.
