# LG OLED stays black

> LG OLED stays black with no picture? Check standby, triage PSU vs panel vs mainboard — AmparioWeb helps with diagnosis, repair and parts.

## In short

If your **LG OLED stays black** — dark screen, **no picture** — it is usually a start or power issue, not a cosmetic panel quirk.

People also search **no picture** and **PSU or panel**. Both happen. Often the cause is the **power supply** (**PSU**, Power Supply Unit / power board) or start chain — not automatically the OLED panel.

## What “stays black” means

You power on, but **no image** appears. Standby LED may be on, off, or blinking; you may hear a relay click or silence.

- Black screen after power-on attempt
- No menu, logo, or backlight glow
- Optional: standby LED behaviour
- Optional: click then dead again

## PSU or panel — rough triage

**PSU / power:** set feels dead or starts then drops; blink codes; click without picture. Aging **PSU** parts are common on LG OLED.

**Panel:** more often artefacts *while powered* — lines, partial image, dead pixels.

**Mainboard:** can block start/video path; see [mainboard or PSU](/en/blog/lg-oled-mainboard-oder-netzteil).

## Safety

**Mains voltage is lethal.** Open chassis and **PSU** carry dangerous voltages. Discharge electrolytics before measuring. **Never work live.**

Unsure? Unplug, do not open. AmparioWeb offers tested parts and fixed-price repair.

## Checks without voltage

Triage only:

- Other cable / outlet
- Document LED and click (video)
- Note model and board number (often EAY…) — [find number](/en/nummer-finden)
- Unplug HDMI sources

## FAQ

**Is a black screen always a dead panel?**

No. Many no-picture cases are **PSU** or start-chain related.

**Same as “won't turn on”?**

Often yes — different search phrase. See [won't turn on](/en/blog/lg-oled-fernseher-geht-nicht-mehr-an).

**Does unplugging help?**

Sometimes briefly. If it returns, hardware (often PSU) is likely.

**Which part first?**

No blind buy. Map via [find number](/en/nummer-finden), then [parts](/en/bauteile) or [repair](/en/reparatur).

**Can AmparioWeb help?**

Yes — model, symptom video, history. [Support](/en/support) or [repair](/en/reparatur).
