Weird burning plastic smell from the back of a LED TV?

Welcome to EP!
If the TV is still under warranty I'd get it replaced, rather than risk a fire.

Hey . . .hey . . . .You say . . .
I've read about this and some sources say it might be dust burning inside of the TV,
I say . . .
No wayyyyyyyyyy
This is a new set . . . . . those SPECIFIC " dust" odors I am well aware with , over all the years . . . . with the MOST distinctly specific ones being asssociated with OLD tube type radios.
Pick one that is on in the years and of the circa 30-40-50's when some units had a HIGH tube count. Leave them stored and collecting dust and floating linters from the air on top of and the sides of their glass / metal s tube envelopes. .
And IF the transcending storage areas were not being OPTIMAL , sprinkle in a bit of raton or meese peese . . . . . or cockly roached deteris.
Fire up that set with now - a - days 128 VAC on it vice . . . . the designed 110-120 VAC . . . . and expect a higher running temp of the tube envelopes.
THEN you will have that VERY distinctive type of odor emanating forthwith after about 10-25 minutes of cooking time..

Now you have a fresh new tee-wee, right out of the box and bristling with all of those fresh ne components and particularly the plastic based xxsupport infrastructure.

I think what you are experiencing is plastic " outgassing " from heated components , and considering your specific area . . . . the units strings of LED backlights and adjunct plastic infrastructure supports / mounts.

AND if your new unit is like the ones lately lauded on TV advertisements, where the whole basic screen depth may only be 1 in thick. Heated areas are somewhat cramped up.

And NOW the words straight from . . . . Mr SONY . . . . and this was ~ 2 yrs back in your sets development timeframe.

New televisions may produce an unusual smell or odor when first turned on. Due to the manufacturing process of components, televisions and other electronic products can have parts with plastic coatings that may produce a smell after the product is first turned on and warms up. The smell will usually dissipate within days of use and does not return. This is normal and occurs with many electronic products.

NOTE: If the smell continues to linger even after the television has been turned off, ensure there is sufficient ventilation around the TV and in the room and the odor will dissipate.
