Please see attached video. Is there an easy way that I can fix the boiler going off and on like this? Or do I need to send it in to the repair shop? Many thanks in advance. https://www.dropbox.com/s/jcawjmn8wbmi25p/20140406_103024.mp4

Hopefully it's just a bad connection somewhere, probably at the back of the neon light that's flickering, if it's not there it will be around the pressurestat, any relay or possibly the heating element. If it's in the high amperage area of the circuit, look for any signs of overheating on the plastic spade connector covers.
I'm hopping the hissing was either you with the steam wand cracked open a pressure cooker or a video sound artifact....if not, check your vaccum breaker and Safety Valve isn't leaking.

If your pilot lamp has an NE2 Neon bulb inside of the lamp assembly, they can flicker after they get old. They can even become photosensitive to light and dark. NE2 bulbs have been used for several decades in pilot lamp assemblies because of their long life, but I think it is fair to say that LED technology is taking over in terms of longevity. If the voltage to the bulb is stable, you simply need to replace the pilot lamp assembly. Just choose a pilot lamp that will fit the hole and match the applied voltage.
