I mentioned this in a thread similar to your issue. Return it(I know, ez for me to say) but these mfg have to be held accountable. There is enough poor quality control and it's going to get even worse.
Good luck!
Definitely return it's a royal pain but doubtful on the partial return. It's to complicated when we get a different tech for every call and even if they give you a ext #you don't get the same person. They're good but they're dealing with a supplier.
