westmc45, welcome to the board..I've had a dead Vl before & just replaced 3..sometimes I think I've just worked them out (& I have some guilt for not always treating them with love!! lol!) after 5 yrs. mine would have well paid for themselves but I still hate to replace them.. I wish I knew of a place or someone to send them to for a re-condition & a complete overhaul but by the time you replace all the parts in the inner-ginnards I think the expense would be just about as much & you're just as well to get a new one..I upgraded to an Iwata Eclipse for my main color black & I'm very happy with it..it's capable of getting a finer line & uses only one tip & needle but it's more expensive to replace these..
It's a pleasure to meet you & I hope you enjoy your stay..
