# LG OLED clicks in standby

> LG OLED clicks irregularly in standby? Often pixel refresh / maintenance — sometimes PSU instability. How to tell them apart, with AmparioWeb next steps.

## In short

If your **LG OLED** **clicks in standby** — seemingly “off” but making soft switch noises at odd times — that is not automatically a total failure.

Many series still run **maintenance** after power-off: **pixel cleaner** / **pixel refresh** and related standby jobs. That can cause short relay-like sounds. Separately, true **PSU** instability produces clicking without a sensible maintenance context, often with start problems.

## Maintenance vs PSU — rough split

Maintenance clicks are often **time-bounded** (after long use, after power-off, in known refresh windows) and the set starts normally afterward. It becomes concerning when clicking feels **chaotic**, comes with **failures**, or boot becomes unreliable.

If it later **won't turn on** or only clicks: [won't turn on](/en/blog/lg-oled-fernseher-geht-nicht-mehr-an) and [clicks twice and turns off](/en/blog/lg-oled-klickt-zweimal-geht-aus). Shuts off while running: [turns itself off](/en/blog/lg-oled-schaltet-sich-alleine-aus).

- Short click soon after power-off — often maintenance
- Irregular clicks for hours without context — investigate
- Clicking + later no picture / blink code — more supply-related
- Pixel refresh aborts or never starts — often PSU stability

## Why the PSU matters in standby

Standby and auxiliary rails must stay stable even when “off”. Aging **PSU** parts can collapse exactly when maintenance draws load — users hear clicks and later see boot failures.

Timer sockets that cut mains entirely can block maintenance — see our timer-socket / pixel-refresh article.

## Safety notice

**Mains voltage is lethal.** Opening the set and working on the **PSU** means dangerous voltages. **Discharge electrolytics**, **never work under power**.

Unsure? Unplug, do not open, use a workshop / AmparioWeb.

## What you can check

Observation only, no live work:

- When exactly does it click?
- Does the set still start reliably afterward?
- Any blink codes or dead starts?

## When AmparioWeb helps

If clicking comes with start problems, self-shutdown or no picture, PSU diagnosis pays off. AmparioWeb supplies tested parts and fixed-price repair.

## FAQ

**Is standby clicking normal?**

Short, context-linked clicks after power-off can belong to **pixel refresh** / maintenance. Chaotic or fault-linked clicking usually does not.

**Can I disable the pixel cleaner?**

Menus differ by series. Permanently blocking maintenance raises **burn-in** risk — see [burn-in & pixel cleaner](/en/blog/lg-oled-einbrennen-pixelschoner).

**When is it the PSU?**

When clicking pairs with boot failure, blink code or self-shutdown — strong **PSU** stability hint.

**Does unplugging help?**

It interrupts maintenance and soft-start. Not a lasting fix; real PSU faults return.
