LG TV Panel Flaws and Expensive Repairs within Two Years

I'm not happy with my LG TV. While watching, the screen went black all of a sudden. After the service center checked it out, they told me that the panel was broken and needed to be replaced. This means that the whole screen needs to be fixed. Even with protection plans and screen protectors, this is not good enough for a TV that is 2 years old. Also, the cost of fixing it is 8500 TL, which is twice the price of the TV. I should not have bought all of my appliances from LG. LG shouldn't have made something with such bad quality. There is no good reason why a TV would break down after only two years. Because of this, I want my TV to be replaced for free under the warranty since it is broken and will cost a lot to fix.
