I have a model UN55NU6950 that I just purchased from Costco. Screen keeps going black intermittently for a few seconds with no sound, likes it's a power cycle. Happens on both inputs, I replaced both HDMI cables and the problem persists. Is there an update that will fix it, or do I need to just return it and buy another TV. Please help!
We are sorry to hear that, what is your current firmware version? And also can you send me a private message with your full serial number?
