You can always verify this by getting a [link|https://www.google.com/search?client=firefox-b-d&q=TV+backlight+tester|TV backlight tester] (supplier examples only) and then use it to test the backlights in isolation i.e. disconnect the power to the TV, disconnect the power board - LED power cable and connect the tester between the LED +ve and LED -ve supply feed on the cable plug, for each strip (or pair of strips). The tester provides the power for the backlights and not the TV
If some of the backlights are faulty, then I suggest that you replace the lot as since some have failed the others can't be far behind.
