A:AnswerIf you're on any kind of cable system or dish you have to program the remote that comes with the cable system. The TV remote won't change the channels unless its programmed to match the cable/dish system.
A:AnswerYes. With the TV facing you on the left side (just above the HDMI plugs) there is a little black plug that is labeled "for factory use only". This is also the headphone jack/plug. Its output level is regulated with the volume control of the TV.
A:AnswerNo - the locations of the legs are determined by slots that are molded into the base of the TV. But the TV does have a mount in the center of the back of the TV so that you can use a wall mount, etc. You could probably make a stand using that mounting space. Good luck!
A:AnswerProbably not a good idea. Most electronic devices work better and last longer in an environment with controlled humidity and temperature.
This TV is lightweight and easy to handle even in the original package, so taking it with you come winter should be an easy option.
