回答“My TV keeps switching off and on again when first started”I've just started to experience this with my UN55KS8000F; I also believe it's related to the power board, due to the consistent power-cycling. I'll add that just before the TV developed this issue, the image on the screen faded to a greenish tint before powering-down. All user-level troubleshooting thus far has not solved the problem. Troubleshooting performed so far: 1) unplugging TV, letting set for a few minutes, plugging back in 2) unplugging TV, holding power button for 10+ seconds, letting set for a few minutes, plugging back in 3) during power cycling, holding power button for 10+ seconds, letting set, plugging back in 4) disconnecting the HDMI on the mini one-connect, and repeating troubleshoot #1 5) disconnecting the mini one-connect completely, and repeating troubleshoot #1 Nothing has worked thus far and the issue remains entirely. I’m going to get my DDM to start testing inside the unit, as well as look for any damaged components. I’ll let you know what I find.
