Resolution

For repair there is a set price one can acquire from the repair department. See Lessons Learned Article #5648 for repair and order information.

For replacement, order a 7798B, then put a CLX card on it, then order a 7718 controller for the triac outputs. It is complex, but the 7728 was a blend of all of these components. 

For the 7728, here is the TCON114 and the Marketing Brochure.
