Dark image giving the impression of a weak tube but if you set the screen to maximum the image looks good | This LG chassis and some other 14, 20 and 21 inch chassis have a habit of corroding the kinescope board, tsound's no point trying to recover it because if it doesn't return | The solution is to replace the kinescope board, you can put the kinescope board from any 20 and 21 inch LG TV. If the kinescope board has showing signs of corrosion, replace to avoid future returns | El Cuajinais Vintage |

If the board has 9 or 12 it will work fine, this 12 or 9 V is in the harness that comes from the main board, this harness is what receives the RGB signal from the micro, | El Cuajinais Vintage |

No backlight, pfc doesn't turn on, no +b 24v to invert it | Check standby voltage on the connector with TV off = 0v and on = 4.7v in the absence of this voltage check possible fault on the main PCI | On pci main q1 = kmbt3904 with leakage +b stanby from reaching 4.7v, you can download the schematic of this model | You tube - Direto no defeito |

The TV turns on, then the speakers beep loudly and disarm. stand by stays on and no longer turns on. When unplugging the power, the TV sometimes turns on and then turns off with a beeping sound from the speakers. This defect can also leave the TV inoperative with the stand-by LED on. | In my case, the defect was in the smd transistor sot23-8 (q702), the transistor code is aon4421. This transistor is intermittent, killing the +5v_sw, which is around 0.35v more or less. all other voltages appear normally. | Before changing q702, solder pins 5 and 6, first removing q702 from the circuit. If the TV works again, just replace Q702 and go hug. | AASF |

Tip: If you have a TV of this model and turn the Stanby LED on and off, it flashes 9 times | Disconnect the speaker from the main board, the impedance of the speaker may be altered | In my case, that was it, I replaced the speakers, replaced impedance, just replace it and run for the hug | valdir anizio |

Does not turn on, no standby - primary voltage only | Ci nw907, r913, r914, cw920, cw923 | Tsound was voltage from the primary but it did not oscillate, I replaced the capacitors, checked the 2 open resistors, made the replace and still it did not oscillate, so by changing the ci it started working again. | JADISON - ELETRÔNICA 2001 |
