AUXILIARY DEFLECTION WINDING DRIVER DISABLING ARRANGEMENT |
摘要 |
In a video display, correction data for a digital convergence arrangement are stored in a first non-volatile memory. During power turn on procedure, the correction data are read out of and stored in a volatile memory. During each deflection cycle, the data stored in the volatile memory are successively read out and applied to an auxiliary convergence winding. When a parity error is detected in the read out data, an output and/or an input of a convergence amplifier is actively disabled to prevent a disturbance of a screen of the cathode ray tube.
