Just does a constant power cycle where the backlight comes on then goes off again. Tried unplugging all cables and using different outlets. Is there a fix for this?
I have the same issue with a UN55KS8000FXZA, which I bought new in April 2017. When trying to power on, the Red light at the bottom of the screen blinks, every now and then audio will come thru and the LCD lights on the TV will come on then go immediately off. I called Samsung support and they had me discconect all cables from the TV, unplug from the wall outlet then plug back in (which I had already tried on my own). Same issue, their next response was to call a local Samusng authorized repair man at my expense as the TV is out of warranty. He troubleshot the TV and determined there was no issue with the Power Supply Board and recommended replacement of the Main Control Board. $400 later for a main control board which has been replaced and I have the same issue. I am extremely disappointed with this Samsung TV and Samsung Support, I will never buy another Samsung TV. I have a Panasonic 42" Plasma TV I bought 15 years ago and it still works, great picture, never had an issue. If a class action law suit is filed against Samsung for this issue, please include me.
I 'm having issues with my KS8000 power cycling on and off and hoping to find some help other than a panel a panel replacing. It's done this in the past but usually letting it sit for a week or two has resolved the issue. I enjoy the tv but given the high price of a panel replacement compared to the cost of the tv makes me question purchasing a replacement Samsung tv.
I see so many threads about the same issue and wondering what Samsung is doing about this? I spent a lot of money on this TV for it to stop working on me 2 years later.. Going the repair route will be 900$ thats insane... The least they could do is fix the issue for me since this is obviously a design flaw on their end.
