suelalla9129 Bro, If your Samsung Smart TV screen is flickering and flashing to the extent that you can't access the options menu, it's likely that the issue may be related to a hardware problem, such as a faulty component or a loose connection. In this case, it's recommended to try the following steps: Unplug the TV from power, wait for about 30 seconds, and then plug it back in. This power reset can sometimes resolve the issue.
 Check the HDMI cable and connections to ensure they're secure and not damaged. If possible, try using a different HDMI cable or input.
 If the issue persists, it's advisable to contact Samsung customer support or a professional TV technician for further assistance or repair.☺️

@@Fix.369thank you sir. That worked. I had the same problem that this person you’re responding to had. So I switched the hdmi port/input and came back clear and back to normal. It’s not flickering at all. Appreciate the tips🫡
