Normal image, normal sound, with a four-finger dark bar on the left side of the screen from top to bottom and characters pulled to the left!!! | The horizontal exciter circuit of these devices is carried out by a pair of transistors 7461 (bc337-25) and 7463 (bc325-25) in complementary symmetry. Replace these two transistors even if they are measuring as good, as they always show a lack of gain. note the "dash" 25 that corresponds to the hfe of the transistors. As a precaution, also replace the capacitor c2405 between the collector and emitter of the npn 7461 (bc337-25). capacitor c2455 is also critical, due to capacitive reactance at high frequency, so replace it. also check the polarizations of the fet 7400. | Perse | |
