I hear you man! It can get annoying and pretty expensive keeping the s9's in tip top shape! I'm glad that I got a couple control boards now so that I won't have to wait if another one goes out. I haven't got time to send mine off yet, besides it still puts out like 650mh with the 48 chips still doing some work, although I would think that it should put out more than that because there are 63 chips in total. I'll try to send it before the end of the week for repair and let you know how it goes. Good luck and Mine On!
