TV working, but no sound. normal image. and control acting. | The sound IC capacitors were repaired: c 613 and c635 of 220/25 dry. | Note: the Q 611 (c2074) is also the champion of this problem. but it wasn't him. the bc 337 takes its place. but you have to invert its base with the collector. | <small> |

It doesn't turn on, if you increase the scrim it appears with a closed vertical and retrace lines at the bottom and turns off. | Change the secondary +12v diode, the diode measures good but does not conduct enough to stabilize the power supply at 12v, causing it to be low. | Replace the diode without measuring. | Lucas Venzke |

When it starts, the LED starts flashing quickly, acting as protection. the protection circuit is good. | To solve the freshness, remove the humor (jc11) and that's it, just the fillet | Rildo aranha | |
