4.4 Service notes for the horizontal output stage All supply voltages derived from the horizontal output stage are protected by means of fuse-resistors which disconnect the defective circuit section from the diode split transformer in the case of a fault. For faultfinding in the deflection circuit, the horizontal output stage can be operated with a reduced supply voltage by unsoldering the service strap S1 and...
