LG tv

I bought a tv in 2014. To date I have had to fix the tv three times. It is only 2018 now. As it is, the tv set is broken again. Same problem as always. Did I buy a faulty set from LG that conveniently became faulty after the 3 test warranty has lapsed? I've spent thousands of rands on repairs. What I could have bought a new tv set with. I don't even have the enjoyment of a tv that I bought 4 years ago.
