I purchased a Samsung Q80 and after only a couple of years, the tv will not turn on. The remote no longer works and the power button on the tv itself does nothing. After navigating the samsung site to actually find an English help line, I was told...sorry sounds most likely like the main board. This tv was well over $2000 when I purchased it and now it is nothing more than a piece of garbage. The service call and part will be more than the cost of a larger, better tv. I will never own another piece of samsung electronics. Absolutely the WORST customer service have experienced and overpriced, yet subpar quality merchandise. STAY AWAY
