# LG OLED burn-in & pixel cleaner duration

> LG OLED burn-in vs image retention, Pixel Refresher / pixel cleaner duration, and why standby with mains power matters — AmparioWeb on the supply link.

## In short

**Burn-in** and temporary **image retention** are known OLED topics. LG sets use care functions in the menu — often **Pixel Refresher**, pixel cleaning, or similar names.

**Pixel cleaner duration** is **not** one fixed minute value for every series: many runs need **a long time** and often run **overnight** in standby. Exact timing is in your menu and **varies by series** — no invented universal minutes here.

## Image retention vs permanent burn-in

**Image retention** is after-images from bright logos, tickers or HUDs that often fade with rest or refresh.

**Permanent burn-in** means lasting brightness/colour differences at fixed screen areas. That is not wiped by a short menu click. Prevention beats late repair promises.

## What Pixel Refresher / pixel cleaner does

The function aims to even cell ageing and reduce after-images. The TV typically needs **mains power** and real **standby** — not a hard cut of the cord.

A night **timer socket** that kills power interrupts those runs. Details: [Timer socket and pixel refresh](/en/blog/oled-zeitschaltsteckdose-pixelauffrischung).

## Pixel cleaner duration — realistic expectations

In practice these are often **long runs**, not a 30-second wash. Some series start automatically after long use; others allow manual starts. Check your model’s support/picture menu for options and status.

During a run the set may feel unusual (dark standby, delayed response). That is not the same as a fault — but if the TV **won’t stay in standby**, care fails for supply reasons.

## When refresh won’t finish — check the supply

If the TV won’t stay in standby, clicks off, or never starts overnight refresh, the **PSU** may be the cause — not a “lazy” pixel cleaner.

See: [won't turn on](/en/blog/lg-oled-fernseher-geht-nicht-mehr-an) and [turns itself off](/en/blog/lg-oled-schaltet-sich-alleine-aus). AmparioWeb repairs and supplies tested PSUs when hardware can no longer carry care cycles.

## Briefly: “dead pixels at the edge” is different

Searches for **dead pixels at the edge** often mean edge artefacts, dark borders or single dead cells — **panel ageing / panel faults**, not the same as classic logo burn-in. Dedicated: [LG OLED dead pixels at edge](/en/blog/lg-oled-tote-pixel-rand). If it looks like panel, diagnose rather than hoping for a PSU.

## Practical tips without panic

Sensible habits:

- Don’t leave static logos and pause screens at max brightness for hours
- Use the remote into standby; leave the plug in (except for service)
- Avoid timer sockets if you want refresh to run
- Read menu hints for Pixel Clean / Refresher — series differ

## When AmparioWeb softly fits

AmparioWeb is not a panel magician against permanent burn-in. We help when **supply and standby** block care functions: tested **PSUs**, **mainboards**, fixed-price repair.

## FAQ

**How long does the pixel cleaner take exactly?**

It depends on series and chosen function. Often **long overnight runs**, not one universal minute count. Check your model’s menu for status and guidance.

**Does Pixel Refresher remove permanent burn-in?**

It mainly helps after-images and unevenness. Strong permanent burn-in is only limitedly correctable — keep expectations realistic.

**Can I keep using a timer socket?**

If you want refresh: better not. Details in the [timer socket article](/en/blog/oled-zeitschaltsteckdose-pixelauffrischung).

**My TV aborts refresh — what now?**

Check whether it stays in standby. Shutdown, clicking or total no-power point to supply — see our PSU articles or [Repair](/en/reparatur).

**Are edge dead pixels burn-in?**

Usually not. Edge dead pixels / border issues are a different panel topic than logo burn-in.
