I originally contacted Laguna, and the only assistance they could be was to offer me a new controller for $1000.00. The controller only has a 1 year warranty and I am over that. I bought a new one from China for around $320 and just need to wait for it. I just thought since I now have two I would get this one repaired so I can have a back up. It is kind of concerning because I don't have a ton of hours on this machine and I always disconnect the controller and put it away after use. It has never fallen or been banged around and yet it just stopped working. The Internet is full of stories like this, and some have got them to come back from the dead. I can not for the life of me get it work so I was looking for a repair center. Laguna did not disclose to me their repair center but I assume it is in China, because the tech said they collect quite a few and then ship all at once a couple of times a year. When they get them back they sale them refurbished for $450.00. They have no refurbished units at this time.
