If the 65-inch Class LG OLED evo AI C5 4K Smart TV 2025, Model # OLED65C5PUA, is turning off after a few minutes and emitting a high-pitched sound, then turning back on to the Home Screen, it may be due to overheating, power supply issues, or a software glitch. We highly recommend you contact our Customer Support on social media (Twitter, Facebook, YouTube, Instagram etc.,) using our handle, @LGUSSUPPORT. The TV will need to be inspected by a qualified service technician to diagnose the issue, and our Customer Support can help facilitate arranging a service appointment. Before calling for service, you may want to ensure that the TV is not overheating. If it is, turn it off immediately and let it cool down. Inspect the Power Supply and make sure the power cord is securely connected to both the TV and the wall outlet. Avoid using cheap or low-quality extension cords or surge protectors. You can go to Settings > General > Timers and disable the Auto Power Off feature, or try power cycling the TV by unplugging it from the power source, hold the power button for 30 seconds, then plug it back in. If these steps do not resolve the issue, it may be necessary to contact LG support or a professional technician for further assistance...^Ivan.
