Tv won’t turn on

I hardly even use that tv the last time it turned on was probably 3 days ago when my mom was trying to turn on the living room tv any way I been an hour trying it to make it turn on and I tried several YouTube tutorials including unplugged a few times I tried a different control remote and nothing it won’t turn on so did it messed up ? Ugh I only have had that tv for a little over a year.
