Be carefull in desoldering the green led. As the pads on the PCB are very small if the temperature with the iron is to long you unstick the pads and broke the wire .As we have the 2 sides to be heated together it is not so easy and the use of a tweezers is delicate. The best is to use a hot air station .For the soldering of the new one, high temperature and more solder are not necessary.The remaining solder is sufficient. The side of the LED is printed on the silkscreen so no problem. I Have changed mine with red and in total 17 leds are necessary.
