zeus thunder x6 help

I have purchased a zeusminer thunder x6 18-20 mhash off ebay and I have worked in it for 8 hours last night to get it to hash. First on pc then laptop and lastly r pi. Tried different drivers, cg/bf miner and configs. I would just start cg miner and the psu would turn off. I took it apart and replace the fans while I was in there checking the cables as per some threads. Everything was connected right. Tried just one set of blades and it worked at about 10 mhash and switches were at (all 4 off)/(only 4 on). I tried the same setup (switches) on the other 2 set of blades and it mine at about 10 mhash. Tried setting switches for all 4 and it crashed. I tried 2 psus both 80+, 1000 watt rosewill bronze and 750 watt seasonic gold. At the moment I'm running 3 blades at about 15 mhash pulling 380 watts at the wall. I believe the switches are set to (all 4 off)/(only 4 on)/(only 3 on). I'm at work atm but I'd love to have something to try for when I get home. I do believe I tried (all 4 off)/(only 4 on)/(only 3 on)/(3 and 4 on) also (all 4 off)/(only 4 on)/(3 and 4 on)/(only 3 on). I did set chip counts to 64, 96 and 128 respectivly. Clock was tried 220, 230, 240. Thanks in advance.

If interested I can send you $20 via paypal for the person who gets it fully hashing.
