Samsung 55 inch curved LED TV Switches on after 1 hour

I’m so disappointed at the Samsung and their TV quality it seems like the quality is deteriorating. I feel like Samsung ****** on some of my pension money. I bought (R12,000) a Samsung 55 inch FHD curved LED TV in 2018 March when I got my pension pay out. In December 2018 the TV had sound but there was NO PICTURE. I took the TV back to Game the TV was repaired TM Electronics. When received my TV I can see where they opened it on the side there is metal that is sticking out. When I’m watching the TV it switches off there are times when I switch it on it doesn’t switch on it will only after an hour it would switch on. This morning I tried switching the TV on around 6:30 am there was no sound no picture I tried several times. Around 8:00 am it finally switched on. In less than 2 years this curved TV has been giving me problems. When people (friends, neighbors, Stokvel ect) come to my house and they complement this TV: I tell them they mustn’t dare they “must never buy a Samsung TV”. I tell them about my horrible experience. I feel like this TV is a ticking boom after the 2 years warranty it will stop working than I have to see myself. R12 000 is a lot of money for a pensioner.
