When you press Power, an LG TV may take a few seconds to recognize input signals and start the picture and sound. If the TV powers on and then shuts off, or the standby indicator flashes and the screen never appears, follow the checks below and contact LG service if the symptom continues.
A short delay at startup is normal while the TV recognizes broadcast or external input signals. In some cases, startup settings or a completed software update can change what you see during power on. If the TV does not display a picture and then turns off, the issue may require inspection by an LG service technician.
After you turn the TV on, it can take about 1 to 5 seconds to recognize input signals from broadcasting or connected devices and then display video and audio.
If the webOS logo appears and then the picture appears, the TV software has been updated to the latest version. This is expected behavior and is not a product fault.
The standby indicator flashes when you turn the TV on and then the TV turns off.
Only sound is heard and the screen does not appear, and pressing Settings/Menu or Volume on the TV remote does not bring up any on-screen display.
Turn the TV on and wait up to 5 seconds for the picture to appear.
If the webOS logo appears and then the picture appears, the TV has completed a software update and this is normal.
If the screen does not appear within 10 seconds, proceed to the next step and consider contacting LG Electronics service if the symptom continues.
