KDL-50W655A
|
Does not turn on, inoperative | Short in the v-com smd capacitor (display board) | Disconnect the lvds cable from the screen to see if the tv gives a signal of life normally smd capacitor c13 shorted on the v-com -- test the fuse and also the diode | Saltech |

KDL 32EX425
|
The TV remains on standby (red LED on) and does not turn on, or if it turns on after a few seconds it turns off. | It was bad contact in the cable that connects the main board to the power supply board. | I messed with the main board connection and it started working again. | Jimi |

KDL-32BX425
|
It turns on normally the first time, if it turns off by itself or if it turns off, it no longer turns on or has a signal from standby, only after 3 days it turns on again, but with the same defect | U701 | Replaced u701 regulator 3.3 turns work normal. | Eletroinfo Ferreira |

KDL-40EX605
|
Reddish image or with lines, normal back light, normal sound and no alerts | Banks of open resistors next to the lvds cable connector, check all, set low value, 1r | Replace resistor banks | Alex Lopes <small> |

KDL-32EX405
|
Turns on and off | Activates inverter protection | Placing an LED from pin 19 to ground disables the protection on the ci ss1091asn | |

KDL-40EX705
|
Does not turn on standby LED blinks 2x | Smd capacitor c6183 shorted on the power supply board | Higorot | |

KDL-40EX655
|
Pisca 2x stand-by | 1m smd resistors changed | When pressing the power button the TV generates 380v in the main capacitor of the power supply and it quickly drops to 170v, check the trigger resistors (tsound are 8 smd resistors in total with a value of 1m each) of the 12v 24v oscillator ci, in my case their values had replaced. | |

All stop inoperative and no LED lights up | Fuses on the internal power supply board inside wsound it connects the power supply fuse.9105, f1002, f1001, f2000 and on the PCI.f9101, f9105, f9102 change | eletronica publisom de natal rgn | |

Glitchy and duplicating image. | Display with altered sync. | On the flat cable of the left tcon between the vcst and vcomg, isolate contact no. 10 from the right to the left, if the image is normal but red, it is a sign that you isolated more than 1 contact, it needs to be a very thin piece of tape preferably kapton. | Antony Garcez |

PS3 SUPER SLIM
|
Game turned on standby, when I activated power it turned off. | Possible short on the 3.3v p-on line, replaced 331/250v ceramic capacitor, photo diode p-on line. | KINKLO | |
SONY |
KDL-40EX725 LTY400HF09
|
Turns on, gives a flash that lights up the LED panel and error 4 protection now activates | Defective led bar kit | In this case, I used an LTY400HF09 display and the LED kit is two bars with 80 LEDs in each, but each bar of 80 LEDs has 02 sequences of 40 LEDs. another case I got and it blinked 5 times it was tcon and it could also be a display | MIGUELTV |

It doesn't turn on, everything is turned off. | Capacitor c936 100uf/10v em curto. | Replace c936 100μF/10v is close to ic804, 3v3 regulator. | MARCONES DE ARARIPINA-PE |

|
League without image. | Lack of 12v on the tcon board caused by the open fuse f1001, caused by a defect in the tcon that blows this fuse. | Replace fuse f1001 and replace tcon. I will try to repair this tcon and post the solution sound. | Antony Garcez |

DX7
|
Distorted sound coming out on channel l | Check capacitor c909 of 1000uf at 35 v below and connect its positive to the input of regulator ic921 which outputs 12 volts and check if it is not bloated | Replace the capacitor because the pre of this channel is distorted and not the protection, but check if the pre is really distorted on pin 13 of the connections between the side board and the amplifier. | Fernando Garcia |

No 19 volt voltage on regulators | The FM radio and the CD mechanics do not work because the voltage coming from a blue power resistor measuring 2.7Ω on the multimeter is missing. Tsound are 3 of these resistors on the transformer board and the third one on the side cover was burned out. | Replace the 2.7Ω fuse and you will have a voltage of 19 volts to power the regulators. | Fernando Garcia |
