The issue was not caused by Samsung but by a bad supplier/maker of electrolytic capacitors that wiped out millions of PCs (Dell got hit with 2 million units alone) and now other electronics. So until Samsung and other makers start making their own parts they will not be able to fix the problem.
With that out of the way, always call in and ask if there is something known about this. I don't see the UN series on the list at http://www.samsung.com/us/capacitorsettlement/ but unless you call you don't know.
The clicking noise is NOT a clear way to diagnose BAD CAPS. Only the tech will do that.
I purchased this TV approx 2 years ago. While watching it the other night it just went black. There is now a clicking noise constantly going as if the TV is trying to power up. After much research i found this to be a common problem in earlier LCD TV's. So much so a class action was filed. All indications point to power supply or more closely The capacitor. Did Samsung not fix the problem in this latest versions of TV? What is my recourse for an expensive TV to die after 2 years?
