I bought a q60, 70 television in august of 2020 and have had only minor issues with it until two weeks ago, when the power supply apparently went out unexpectedly. all electronic components are plugged into a surge protector, and the other items plugged in (sound bar with remote speakers and set top box from the cable company) were still functioning, but the tv was dimly back lite and would shut off, restart on it's own. then shut down again. This happens when it is plugged in. i called samsung and they said they would get back to me with an appointment for a tech to come out to my home. the soonest they could get out was 9 days after the first call, so i waited that day, no call and no show. i called and was told that the 'care now' associate forgot to call me, that a part didn't show up (how did they know what part to have, they hadn't seen it yet?) and they were sorry-they made the appointment for monday morning (i waited on a thursday so it would be another 4 days for someone to show up), I said fine...well today is monday, no show, no call...this has a full parts and labor warranty for 5 years total, it is just short of one year since i purchased it at costco. my advice is to avoid samsung, their products seems to not be the quality i thought they might be, and their service is pretty much non-existent. common courtesy dictates that customers be communicated with, and they seem to not be capable of common courtesy. my time is worth something, and if i had not been here when their tech showed up, i would be in the wrong for wasting their time, what about my time? think seriously before you buy this brand, and look on line for complaints there are thousands relating to poor quality and worse, poor service. never again.
