The "silver box" is the DCU or Digital Convergence Unit. It stores your convergence settings and sends them to the Convergence Out IC's when the set is powered on. It is also quite costly so before I'd replace it I think I'd recheck the STK's and the resistors. The tolerance of the resistors is very important. They must be within 5% of the value listed. Also, sorry to say but there are a lot of bogus STK's out there. Be sure to purchase them from a well known distributor.
