Samsung DOES NOT back up their products. I haVE a problem with a Samsung TV that began right away. I first thought it might be my cable company so began dealing with them. They came our and replaced EVERY WIRE, CABLE, DEGITAL BOX leading to the TV. Still the sound on this new TV just goes out whenever it decides to. They have come out 4 times in fact trying to help. It is not a cable issue but Samsung won’t admit that. I have to change channel and then change back and it will have sound again. We have 5 TVs in our home and others are fine. One of the others is also a new Samsung purchased at the same time. It’s fine. I have worked with Samsung numerous times on phone, online chat, sent all my receipts, credit card statement proving the purchase. They will not do anything to replace this TV. The receipt I sent them of course showed that we had also bought an extended warranty that kicks in after the Samsung one expires. On seeing that, I was told just to use that warranty if the problem continues after warranty has expired. They don’t honor their warranty at all. DONT BUY SAMSUNG.
