LED TV backlight too high = damage?

Hi folks, I tried searching but couldn't find anything on this.

I bought a used Samsung UE32F5000 the other day and am really liking it. The seller, however, warned me not to turn the [Backlight] setting up too high as it's a common cause of faults on these TVs. True or rubbish?

I ask because to my eyes the [Movie] mode looks best, which pushes the backlight setting up to 20/20 to get the brightest whites. I can use a bit of a lower setting, down to 14 or so is still fine, but I wonder if it's necessary.

Thanks for that. I have contrast near max (95 I think) and don't find backlight 20/20 too bright. Maybe it's just not a particularly bright screen?

For whites reference I'm using a snowy/arctic bit of Life (the BBC nature documentary) and I want that to be borderline dazzling if possible.

So you're saying the concern about max backlight is probably not true?

Thanks folks.

jpaul- The high-current thing is what I was wondering. It does however seem to be a very low-powered TV: the sticker on the back says 60 W max, 40 W typical. Partly I guess this is the size (32"). I will try and find my watt meter and measure.

Vertigo1- thanks, it's not HDR as far as I know.

hornetstinger- I've got all the showroom settings off (dynamic this, extra deep blacks that). The Life BD I mentioned has a simple but very useful set of test screens that I'm also using to tweak the settings. The high contrast is needed to get the whites right (test screen with A B C in shades of near-white). As above it's really not a very bright panel even at max in a pitch black room.

I think I've currently got it at 20 ish now (from a default of 50) based on a sharpness test pattern (vertical lines of various thicknesses) and a scene of something like a million birds/bats flying around (can't remember ) but will experiment with 0 too, cheers.
