Note:  Please Read

This is the most difficult circuit board I have ever had the “pleasure” to replace. The procedure involves desoldering from the old board and then resoldering the wires onto the new board!  You need to take extreme care to track which-wire-goes-where.

I DO NOT recommend that any but the most advanced repair technician try to use this board!
