Sometimes it works normally, sometimes it turns off | 3v3 regulator with a problem, 5v was coming in and 3v3 was not coming out, consequently tsound was a lack of 3v3 at the input of the 1v8 regulator, which also had no output or input. | Changing the 3v3 regulator and 3 470 x 25 bloated capacitors in the sound amplifier circuit. | |

Image closing horizontally, when closed too much, it would go out of synch with h and v, lose RF signal, turn off and keep hitting the relay. | 10nf capacitor c105 (near the tuner and on the 5v power line of the tuner and pins 2 and 54 of the processor) with excessive leakage, reducing the 5 volts to 3.8 volts. | Replace the capacitor or leave it without. | Lourenço (SEMED) |

Led pisca 4x e volta pra stand by | A negative voltage of 12v comes out at the power supply and goes to tcom. after the fuse (f8) tsound are two coils (b31 and b32) and immediately after an 8-terminal switch (trans. q27) | It was not "switching" the -12v, close it directly to confirm the defect (pin1 with pin8). This is just a guide to testing, the correct thing to do and changing the tcom card. |
