The blinking red light on your LG - 65" Class B5 Series OLED AI 4K UHD Smart webOS TV (2025), Model # OLED65B5PUA, indicates a power supply failure, (main board) malfunction, or a stuck firmware update. It is a safety mechanism indicating the TV cannot boot properly, often caused by a failed power board (e.g., faulty capacitors) or a corrupt update loop. You can try unplugging the TV, for at least 10–30 minutes, then press and hold the physical power button on the TV for 30–60 seconds to drain residual electricity before plugging it back directly into your wall outlet, to see if that resolves the issue. Unplug all HDMI devices (game consoles, soundbars) as a faulty device or cable can cause a boot loop. If the light blinks slowly, the TV might be updating; wait at least 10 minutes...^Ivan.
