MIS-CONVERGENCE CORRECTION APPARATUS FOR DEFLECTION YOKE

摘要

PURPOSE: A mis-convergence correction apparatus is provided to prevent overloads of circuit by permitting a current to flow to a coma-free coil of a deflection yoke even when the coma-free coil is disconnected. CONSTITUTION: A mis-convergence correction apparatus comprises a YHC mis-convergence adjustment unit(20) for adjusting a mis-convergence on a screen by varying the flow of current to a coma-free coil(51 or 52) arranged at an end of a deflection yoke even when the other coma-free coil(51 or 52) arranged at the other end of the deflection yoke is disconnected; and electron beam adjustment units(30,40) connected in serial to the YHC mis-convergence adjustment unit, and which adjust red, green and blue electron beam signals output from the YHC mis-convergence adjustment unit.
