My problem start today. Bought less than 2 years . I can't believe a $2000 tv just break down so EASY. My other cheaper Samsung last so much longer. I am hoping Samsung can help solve this problem .
SOLVED!! My Samsung tv has been randomly turning itself on and off for the past few months. I tried every suggestion including changing to a different HDMI port, checking power supply and connections, changing remote batteries, turning off energy saving feature, etc. It’s been extremely frustrating but I was determined to find a solution. And I finally found the fix!! There is a feature on Samsung TVs called Anynet. This allows you to connect several devices to your tv so that you only need to use a single remote control for all the devices that are connected. You can access this feature in your tv settings or by a small button labeled Anynet on the Samsung remote. If you are experiencing sudden shut offs, you should disconnect this feature. Since I have a cable box connected to the tv, I use the cable remote anyway and therefore have no use for this feature. After disconnecting Anynet, the tv has not turned itself off again!! Finally, a solution that works!!! Hope this works for you too!!
It seems this is a common problem....I too have a UN65KS8500FXZA TV doing the same thing. It turns off and on in an endless cycle. turned off for 12 hours, no change. I had a geek squad a tech visit yesterday and stated this could cost $1500 to repair and he advised to just go get a new TV!! This is only 2 years old. I am livid with Samsung .
Could you send us a private message with the full model and serial number for the television? http://bit.ly/2ihPL97
I am curious as to what you plan on doing about your TV. I am assuming the TV is out of warranty and I am positive that the cost of repair is out of the question. I spent last evening checking circuits on the PCB (Main and power supply) and all circuits check out. The Samsung technician was correct in his diagnosis but I believe he was wrong on the cause. He told my wife the control panel was shorted out due to a power surge. I do not buy this for many reasons; first, because we have a whole house line conditioner and surge protection. Secondly, I had the TV and all of the accessories on another surge strip; thirdly, the power supply PCB would be the first to go due to an incoming surge and the PS PCB checked out fine.
I having a hard time swallowing this whole thing; I bought the TV as an investment and to have the TV repaired with a new control panel would cost more than the TV is worth. Samsung is making me feel that TV's are not an investment and they are disposable like a small appliance. I would like to know or see the data on the life expectincy of a Samsung TV in general and specifically the UN65KS8500 and alike.
