Suggestions.- The first thing will be to know how much of bmas we have. The second will be to check the oscillation. 2.- As it is without the flyback and without the hot, place your frequency meter at the base of the hot and check how much you have, it should be 15750 cycles. If all is well, and you already checked the vertical voltages and even changed it, we can check the flyback in the circuit. Question: Do you have experience? greetings everyone. Felipe ascencio

companion. If we already have a good image, but no audio, then: 1.- remove the audio ci and check the voltages. With an audio tracker you locate which audio input pin and there you place your tracker. says that integrated is the audio to look for it and tell you what power it should have. Comment how much you have of bmas. 2.- if the speakers are 8 ohms, you remove the speaker and place a resistance of 8 ohms 10w. This allows you to check the voltjes. If possible, you can feed the audio from an external source with less voltage. greetings everyone. Felipe ascencio
