To move the TV: You must activate the little buttons in the nightstands in a specific order; the strange plates on the wall in the dining room give you the clue for the order (the number of flowers, the color of the flower)
After the TV is moved, a panel will be revealed. The code for that is on the calendar. Look for two days that are out of order, enter those 4 digits.
Have fun!
Power to UFO - click on square icons above doors/items on wall. Two of them will move revealing a round red light. Click on it to turn it green. Go back to the area where the giant batteries are and click on the 4 square button on the control panel to turn the power on.
