You might consider seeking a warranty replacement from where you bought it from, or talk to FriedCat. Not sure what their policy is on hardware issues, but I think shipping with an entire bank of chips down is grounds for a replacement already.
The general policy is this would be a warranty replacement. One or two chips is okay but a bank would be faulty as there is no way to modify the blade to improve. An alternative you could suggest is to get a reduced price on either this blade or a new one.
Remember to put future support requests via the support thread where there are lots of people with the same hardware who can help:
