Vertical closed and it wasn't just the vertical drive | I observed, after checking, that the entire vetial circuit was perfectly blocked, but tsound was no signal to amplify. checking the ci supply voltages (q 501), I observed low voltage on pin 36. and consequently on q830 (7805). I replaced it but the voltage did not return to normal. I decided to turn off each component powered by this voltage, turning off the track, and I saw the smd 74h4053 shorted | It was just a matter of replacing it with another original one as well. And that was it. | ZAKSOM |
