# LG OLED will not turn on: switch off Quick Start+ > LG OLED sometimes does not turn on? Switch off Quick Start+ and test for a few days. If the TV then starts reliably, you know whether the feature is involved. How to run the test and how to read the result. Your **LG OLED** sometimes does not turn on: sometimes it starts at once, sometimes the screen stays dark. A test in the settings shows whether the Quick Start+ feature is involved. The test is free. Changing the setting takes a few minutes, the observation a few days. You only need the remote. ## In short **Quick Start+** (also called **Q-Start+**) puts the TV into standby when you switch it off instead of shutting it down. It then starts faster later. A customer reported the same fault only with Quick Start switched on. Without Quick Start her TV started reliably, no matter how long it had been on or off. This is a finding from our workshop, not a manufacturer statement. ## What Quick Start+ does According to LG support, the feature puts the TV into standby when you turn it off so that it can turn on quickly later. LG notes three points: - The TV starts faster. - Standby power consumption may increase. - The feature is only available on certain models. ## How to switch Quick Start+ off **1.** Press the settings button on the remote and choose **All Settings**. **2.** Open the menu path for your webOS version and set Quick Start+ to **Off**. If the entry does not exist on your model, your model does not have the feature. The names are from LG's English menus: - webOS 22 and webOS 6.0 (2022 and 2021 models): General → Devices → TV Management → Quick Start+ → Off - webOS 5.0 and webOS 4.5 (2019 models): General → Additional Settings → Q-Start+ → Off - webOS 4.0 and webOS 3.5 (2018 and 2017 models): General → Q-Start+ → Off ## Your test: first with, then without Quick Start You only need patience, no tools: **1.** Write down when the TV fails to turn on: after a short break, overnight or after long viewing. **2.** Switch Quick Start+ off and unplug the TV from power for a moment. **3.** Use the TV normally for several days. Repeat the situations in which it failed before. **4.** Check whether it now starts every time. The first start takes a little longer without Quick Start. That is normal. **5.** Then switch Quick Start+ back on as a test and check whether the fault returns. ## How to read the result **The TV starts reliably without Quick Start but not with it:** Leave Quick Start+ switched off. Our assessment: with Quick Start+ the TV never shuts down completely. If the standby power supply is unstable, wake-up fails. This can point to components that are wearing out on the power board or the mainboard. Have the boards checked on the device. **The fault remains without Quick Start:** Have the power board checked.

If the TV shows nothing at all, read [standby light off](/en/blog/lg-oled-standby-led-aus). If it clicks while switched off, read [clicks in standby](/en/blog/lg-oled-klickt-im-standby). ## Safety notice **Mains voltage is lethal.** The test only uses the menu and the remote. Do not open the TV and do not take measurements while it is powered. If unsure, unplug it and ask us. ## Options at AmparioWeb If the fault remains, or the TV only starts reliably without Quick Start, have the boards checked.
