40% below without vertical image... that is, tsound was only 60% image | C563 and c562, then c406 | I replaced capacitors that supply the +15 and -15 (c563 and c562, even though the capacitance was not so out of the ordinary), and the vertical image opened, but tsound were small horizontal stripes at the top (5 or 6). Then I checked the generator signal (pin 3 of the vertical) and it was altered, I replaced it and the c406 image was perfect | David |

It turns off in a few minutes, sometimes tsound is a beep from the speaker, it does not obey commands from the remote control or the TV. | Lack of grounding in the housing of the x5 crystal (16mhz) close to u8. definitive solution | Take a piece of bare jamper, go around the crystal and solder it to the housing and to a ground point. Obstodo topics previously sent are correlated to this defect. | cici.muniz |

Sound failing, especially when the volume is medium to high. | Suspension of both speakers destroyed. | Just replacing the entire speaker or just the speaker. | 2000 |

Backlight flashing intermittently | Bad contact on the vr9530 potentiometer on the power supply board (it is on the part of the inverter close to the connector that goes to the backlight) | The potentiometer travels just under one turn, so first of all, mark the original position with a permanent marker, use contact cleaner spray and turn the potentiometer to remove the oxidation. return to the original position. | 2000 |

Stop, dead power supply | Ci um801s (q0765r) blown, fuse fb801s open, capacitor cb806 and cb808 bloated, transistor qm801 shorted, zener diode zdm801 shorted and db804 shorted. | In my case, it was just a matter of changing these components and running for the hug! transistor qm801 was blown and I couldn't see its reference, but as it pollarizes the qm801, I took an A4 from scrap and the zener diode is a 12v zb smd I took from scrap too! | Rafael Sena |

Normal power, low sound | Defect possibly chopper transformer, change in winding, changing current, photocoupler 817 (pc901) does not read due to transformer | Place a 100k resistor on terminals 3 and 4 on the photocoupler (pc910) and the audio returns smoothly | Matheus tony |

Does not recognize a/v only component | I did a reset and it didn't work, so I connected the white and black wires to the blue RCA of the input connector. | ||

Does not polarize | In my case, I changed the value of the rm61 resistor from 27k to 47k and placed an in4007 diode in series, and it worked. | Replace rm61 from 27k to 47k | MARCONES DE ARARIPINA-PE |

LED turns green but does not turn on lamps (backlight) tsound was no voltage of 12 and 24 volts | Diode d7 open: just change it and give the budget. It generates a voltage of 12 volts to power u5 | Replace diode d7 in4007 with a more powerful one. | ELETRONICA SALES.NATAL RN |
