We have inspected your Wii U gamepad controller. We have found the issue to be with the main motherboard electronics which must be repaired at the connector. This repair requires the disassembly of the controller to repair. In addition our technician noted that the buttons require cleaning and dust was found on the main board and screen. The dust need to be thoroughly cleaned out or you run the risk of shorting a component on the board. The total cost for repairs to the analog stick electronics on the main motherboard, cleaning the controller, labor, with in store pickup is $68.95. That includes a 90 day warranty on the parts and repair. As an alternative we can simply return back your unit to you and the inspection and diagnostics fee is $26.95. Please make payment below to proceed.
