# LG OLED dead pixels at edge

> LG OLED dead pixels at the edge? Panel ageing vs burn-in — distinction and when to diagnose instead of hoping for a PSU.

## In short

**LG OLED dead pixels at the edge** often means dark/dead cells or edge artefacts — **panel ageing / panel**, not the same as logo **burn-in**.

Unlike [burn-in & pixel care](/en/blog/lg-oled-einbrennen-pixelschoner): burn-in = ghost logos; edge dead pixels = failed cells/edge.

## Not the same as burn-in

Pixel refresher targets image retention / burn-in. It usually does not fix **dead cells** at the edge. See also [vertical line](/en/blog/lg-oled-vertikaler-streifen).

## Why not a PSU swap

A **PSU** swap (**PSU**, Power Supply Unit / power board) does not fix panel edge faults. Document (photo), model, warranty/panel diagnosis — AmparioWeb focuses on power boards but helps triage.

## What you can do

Photo on full-screen grey/white, note model, check warranty, do not expect miracle pixel-fix apps.
