So we're still getting used to our "new to us" 2016 Sunstar LX 27n. And the other day I was showing a friend through our new toy and was in the bedroom and went to turn on the TV. It didn't come on. Tried the remote, nope, tried the side switch, nope. Said hmmm, and moved on. So this morning I decided to go and troubleshoot it. Swung the mount out from the wall, pulled the screws from the back and put it down on top of the dresser. Found the power input and checked the voltage, nope, no 12V. As I was standing there I glanced up and there, above the power outlet is a switch that says "TV". Turned it on and low and behold, the TV comes on. Dumb.
Obviously, we haven't tried to use the bedroom TV since buying our MH. There's probably a lesson here somewhere...
