P02
LG Smart TV
Severity: CriticalWhat Does This Error Mean?
P02 on an LG TV indicates a fault specifically on the power board — a component has failed in the secondary power stage. This prevents the TV from properly powering the main board or panel. P02 is a hardware fault requiring professional repair — the power board typically needs replacement.
Affected Models
- LG OLED C2
- LG OLED C3
- LG QNED85
- LG NanoCell 75
- LG UHD UP7670
Common Causes
- Secondary stage capacitors on the power board have failed
- Power regulation circuitry has developed a fault
- Voltage spike has damaged specific components on the power board
- Poor quality power supply in the home causing recurring stress on the board
- Power board has reached end of life due to age and heat cycling
How to Fix It
-
Unplug the TV from the wall for 60 seconds, then try powering it on again.
A capacitor discharge cycle occasionally clears a transient P02 — but if the board is truly faulty it will return.
-
Plug the TV into a different wall outlet on a different circuit to rule out a mains wiring issue.
Chronic under-voltage or over-voltage from the mains supply can stress the power board and cause P02.
-
Look up your TV's serial number on LG's warranty check page to confirm coverage.
LG's standard warranty is 1 year from the purchase date — power board faults are covered.
-
Contact LG support at 1-800-243-0000 and report P02 — they may arrange a free repair if under warranty.
Have your model number and serial number ready from the label on the back of the TV.
-
If out of warranty, get a quote from an LG authorised service centre for power board replacement.
Replacement power boards for LG TVs typically cost $80–$200 in parts, plus labor.
-
Consider using a quality whole-home surge protector or UPS to protect the new board from future voltage spikes.
An APC or CyberPower UPS (uninterruptible power supply) provides clean, stable power and surge protection.
When to Call a Professional
P02 requires a qualified technician — power boards contain high-voltage components that are dangerous to handle without training. Contact LG support first to confirm warranty status before paying for any repairs. Request that the technician test individual board components before recommending full board replacement.
Frequently Asked Questions
What is the difference between LG TV P01 and P02?
P01 is a general power supply error — the board is not delivering power correctly to one or more components. P02 is a more specific fault in the secondary power stage of the same board. Both codes indicate power board failure and require the same type of professional repair.
Can P02 on an LG TV be caused by bad power in my home?
Yes — chronic voltage fluctuations or poor power quality can stress the power board over time. A UPS (uninterruptible power supply) provides clean, stable power and prevents this. If you have frequent power flickers or brownouts, a UPS is a worthwhile investment to protect any TV.
How long does a power board repair take for an LG TV?
An authorised technician can typically replace a power board in 1–2 hours on-site. If the board needs to be ordered, the repair may take 3–7 business days for parts to arrive. LG authorised service centres often stock common power boards for popular models.
