Hi. We regret to read that your 77-inch Class LG OLED evo C4 4K Smart TV 2024, Model # OLED77C4PUA randomly shuts off. Several factors can cause the TV to randomly shut down, and troubleshooting is required to resolve the issue. If you have it connected to a voice assistant like Alexa or Google Assistant, verify that routines set on those devices aren’t triggering shutdowns. You can try disconnecting the TV from Wi-Fi as a test and see if the behavior persists without Wi-Fi. The issue may be due to a faulty power supply or a loose connection to the outlet if the power cord's plug is not securely inserted...^Ivan.
