Neon Signs Beer

How to fix a neon beer sign w / some broken pipes?
I have a neon light beer I would go so far as to extinguish. Some the pipes are broken, the whole thing flashes for about half a second and then turns off when you turn. I imagine that the pieces could never be broken again to work, but I can get only the parts that work? It seems like a light "Christmas" is a stage in the tightening and the other will not work.
That has to go to a sign maker, will have the necessary gas piping, and all that it takes a lot cheaper than you could get in shape.
