I purchased a 75" Samsung from Granite Furniture two years ago. I did not purchase the extended warranty with the reasoning that a $4000 dollar television should be good to go........high quality, right? All of a sudden, I had no controls to the TV and when plugged in, just cycled on to off. I had no sound, no menu, no picture, nothing!!! I called Samsung. They did not offer any service to my area and I had to find my own technician. I did so. Replaced the "Power Board" and "Main Board". The television now comes on to a blue screen. Still no picture, sound, or menu control. I called Samsung for HELP. They offered very little but to take it back to the technician and try again. Sorry, but $800 dollars later, I could've bought a 78" TV at Walmart for $800. Lesson learned: DON'T BUY SAMSUNG.....anything. Their products are substandard and service is pathetic. I would give them less than one star if it were offered.
