A METHOD AND A GRADIENT ADJUSTING APPARATUS FOR AUTOMATICALLY TESTING AND CORRECTING THE GRADIENTS OF A SCREEN OF A VIDEO DISPLAY DEVICE SUCH AS A CATHODE RAY TUBE (CRT) AND A FRONT CASE (205) IN A PRODUCTION ASSEMBLY LINE BEFORE ASSEMBLING THE CRT AND THE FRONT CASE (205), THEREBY REDUCING UNNECESSARY OPERATIONS AND MINIMIZING INFERIORITY OF THE VIDEO DISPLAY DEVICE. IN ADDITION, DEATH FROM SHOCK CAUSED BY A HIGH VOLTAGE IS PREVENTED BY AUTOMATICALLY SUPPLYING THE HIGH VOLTAGE, A DEFLECTION VOLTAGE AND A GRADIENT TEST PATTERN TO A CRT ASSEMBLY (204) WHICH IS TRANSPORTED THROUGH A CONVEYER BELT (201).
