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.
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 and turns itself off. 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. 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.

Frequently asked questions
- 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.
- 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.
- Are edge dead pixels burn-in?
- Usually not. Edge dead pixels / border issues are a different panel topic than logo burn-in.
