Banks asks for a dated bill of sale from an authorized dealer, a service history and an RMA before it will look at a part, and it ships repaired parts back freight collect. Contact NVMOS first: we have your order record, can help confirm whether the problem is the part or the setup, and will help you get the RMA and paperwork together. Have your order number and a few photos of the issue ready, then call or text us at (920) 249-7744 or send us a message.
