you being able to do something yourself would depend on the type of problem in the noid causing the leak as well as on your confidence in doing maintanence on the noid. Some people have a problem doing that kind of stuff others dont.
I think noids run around 80 dollars. So if you do send it to blast to be fixed dont be surprised if you have a bill around that much as long as nothing else is wrong due to user error. If the problems were caused by something out of the control of the user then blast will usually fix it for free.
