LCD keep blinking, blinking referring to the LCD backlight or the message itself? What type of power source you are using? 9V battery or AC to DC adapter? Anyway, if the problem still persist, please fill in the form under support tab at Cytron website, the technical team will follow up with you.
Never tested LM35 in that condition, but pin 2 is output and even if you do not connect anything, it should not cause any extreme heat. Is the pin 1 and pin 3 is correctly connected? Because in the data sheet, the TO-92 package is bottom view, not top view. A lot of user make mistake on that, and connect the +Vs to Gnd and Gnd to 5V.
