Hi JY, We are sorry to hear you are experiencing this issue with your new 55" BRAVIA 8 II OLED TV. The behavior of the TV switching itself on and off while flashing monochrome colors typically indicates that the TV is performing an internal diagnostic, an automatic OLED Panel Refresh cycle (which can show different test patterns), or it is encountering a software issue or a component error. Since the TV is new, we recommend performing a Power Reset first: simply unplug the TV's power cord from the wall outlet for two minutes, then plug it back in and turn it on. If the issue persists, please ensure your TV's software is updated to the latest version, or contact us directly so we can gather more details on the exact sequence of flashes and colors for specific troubleshooting. Thanks for choosing Sony. Best regards, Eliab
