# LG OLED clicks twice and turns off

> LG OLED clicks twice then shuts off, or clicks with no picture? Relay engages, protection aborts start — often PSU, short or panel load. AmparioWeb helps with diagnosis and repair.

## In short

If your **LG OLED** **clicks twice** (click-click) on power-on and then **turns off** or stays black, the start chain often engaged — and **protection** aborted the boot again.

Many users call it **clicks but no picture**: the **relay** / soft-start on the **PSU** (Power Supply Unit / power board) briefly engages without image or sound. Causes often sit in an aging **PSU**, a short toward the mainboard, or high **panel load** — not automatically a dead panel.

## What the click-click usually means

A single switch sound at power-on can be normal. **Two short clicks** then darkness suggest supply and protection cycling in a short loop.

Sometimes a **blink pattern** on the red / standby LED follows. **Flash counts vary by series and year** — there is no universal official LG table for every chassis. Count and document what *your* set shows (including **3× / 4× / continuous** blinking).

- Click-click on power-on, then off immediately or after seconds
- No picture, no sound — only click or brief LED activity
- Sometimes blinking red LED / boot-loop-like pattern afterward
- After unplugging, brief different state, then the same click-click

## Common causes: PSU, short, panel load

In practice three suspects lead: aging parts on the **PSU** (including film capacitors), a **short** or load fault toward the mainboard, or **panel load** that trips protection.

## Safety notice

**Mains voltage is lethal.** Open chassis and **PSU** mean dangerous voltages. **Electrolytics** can hold charge after unplugging — **discharge** before measuring or desoldering. **Never work under power**.

Unsure? Unplug, do not open, leave diagnosis to a workshop. AmparioWeb offers tested parts and fixed-price repair.

## What you can check safely (no live work)

Goal is triage, not live debugging:

- Rule out another mains cable / outlet
- Document click pattern and any LED blinking on video
- Note model and board numbers (EAY / EAX) — [Find number](/en/nummer-finden)
- Whether the fault is intermittent

## When AmparioWeb helps

With **click-click and no picture**, map **PSU / mainboard / load** before discussing a panel swap. AmparioWeb identifies boards, supplies tested parts and repairs at a fixed price.

## FAQ

**Are two clicks always a fault?**

A single switch sound can be normal. **Clicks twice and off** or **clicks but no picture** is a classic protect/start pattern — diagnose, do not wait for self-healing.

**Is the panel dead?**

Not automatically. Often **PSU** protection stops the start. Panel faults more often show image artefacts with supply already running.

**What about 3× or 4× blinks after the click?**

Patterns **vary by series**. 3×, 4× or continuous blink / boot-loop are clues — not a universal code table. See [red LED blinking](/en/blog/lg-oled-rote-led-blinkt).

**Which part first?**

No blind buy. Map via [Find number](/en/nummer-finden), then tested [Parts](/en/bauteile) or [Repair](/en/reparatur).

**Can AmparioWeb help?**

Yes — with model, video of the click/blink pattern and history. [Support](/en/support) or [Repair](/en/reparatur).
