Hello colleagues ... Samsung TV does not have the screen backlight and sound good. I would like to know how I can test the output voltage of the source (invert) I test them to dc with auto range and vary .. .. and it doesn't mark anything just mV ... I would like to know how they are tested .. and how I can test the LED strips .. I am going to leave you photos ...
