Abstract:
A method for assembling a digital convergence monitor at more than one manufacturing site, comprising:at least partially assembling the digital convergence monitor at a first manufacturing site by mounting a deflection yoke on a cathode ray tube forming a CRT-DY assembly, the CRT-DY assembly being uniquely marked with an identification code; adjusting the digital convergence monitor at the first manufacturing site to produce revised control data; marking the revised control data with the identification code; sending the revised control data from the first manufacturing site to a second manufacturing site; assembling the digital convergence monitor at the second manufacturing site by receiving the CRT-DY assembly at the second manufacturing site and mounting the CRT-DY assembly in a digital chassis forming the digital convergence monitor, the digital chassis comprises a memory connected to the deflection yoke; storing the data in the digital convergence monitor at the second manufacturing site; and adjusting the digital convergence monitor at the second manufacturing site, where the adjustment at the second manufacturing site is recorded in the data by measuring convergence and distortion in the digital convergence monitor, and adjusting the revised control data stored in the memory of the digital chassis to correct performance of the digital convergence monitor and to generate a final control data; marking the final control data with the identification code; sending the final control data from the second manufacturing site to the first manufacturing site; retrieving the revised control data from memory at the first manufacturing site, where an identification code of the retrieved revised control data matches an identification code of the final control data received from the second manufacturing site; and comparing the final control data with the retrieved revised control data at the first manufacturing site.
