I’ve noticed this TV automatically brightening and dimming depending on the brightness of the scene that I’m watching. All power energy saving and contrast balancing settings are already turned off. Other people who have the same general model TV said they fixed this by opening the service menu and adjusting the PWM settings. They said they did this by pressing the info, menu, mute and the power buttons to enter the service menu but this does not work for the specific model TV I have. Please let me know how to open the service menu so that I can fix this very annoying issue. Thank you.
