Good morning @fabzilla I do apologise I forgot to reply to your first post, have you resolved the issue? If not tell me where you need the pictures taken and I will take them for you, I have the 2019 QE65Q70R.
Good evening .. Could someone with a Samsung q70r help me with the parameters of the secret menu? Thank you all
I am not aware of a secret menu, pray do tell and I shall help.

Thanks friend ..... Following the video I need the sub setting parameters .... The first 5 pwm .... I suggest you set them to 100 to eliminate global dimming in dark films ..... Do first picture of the default parameters .... To be able to set it if you don't like setting !!! If you want to stay that way ... Please take pictures of the default parameters so that I can memorize them. Thanks

I have the app but all sites I checked for the combination stated the following:
"The TV must be OFF and receive the IR commands (Mute > 1 > 8 > 2 > Power) in order to enter service mode"

Do you know the key combination to use on Smart Things?

Hi, I just got a Q60A and I've mostly disabled dimming by setting PWM_INI_2D and PWM_MOVIE_INI to 100, but I do still get dimming when there's a fully black screen, which is distracting and noticeable when a black screen appears in certain movies, especially since the dimming fades on and off as opposed to being instantaneous. Anyway, I know to disable this, you're meant to set PWM_MIN to whatever the backlight is at, but this TV doesn't have a PWM_MIN (only a PWM Mid and PWM Max -and my PWM Mid is a 8, by the way, which was the default). So my question is, what can I adjust in place of PWM Min so that the dimming on fully black screens won't trigger? I've also tried disabling the Eco settings in the EPA of the service menu, which didn't work.
