The rear LCD on my D800E was only bonded to the rear cover--I bet the D600 is the same. You can put the rear cover with LCD in a vise (gently) and heat gingerly with a heat gun or hair dryer. If you're afraid like me, you can tape a thermocouple bead to the inside of the cover to monitor the temperature. Before reaching 200F, the LCD will fall out. You can push lightly with a wood stick to help it along. The new LCD will have pressure-sensitive adhesive already in place with release paper that you pull off before installation.
