Samsung Corporation Customer Service non existance for help

I bought a 55" Plasma TV in Jan 2011. IN Aug 2011 it would not turn on. Service replaced the capacitor. Now, 5 years later, with little use on TV, it happens again. I understand it has been 5 years however, this has apparently been a problem from new. This TV is in a home with 1 occupant and gets little use. $1000 for a TV should last longer than that. I contacted Samsung customer service.

I went back and forth with them several times sayng this has been an issue since new and Samsung should stand behind their product. I got no help repeatedly. I asked that a manager contact me. They did, but delivered the same message: sorry, you're out of luck. I will not purchase any more Samsung products and will register my complaint in other agencies. They apparently care less about their customers. Tis fix sould be on them. I submitted the original service request as well as invoice. They refuse to take responsibility for a faulty product.
