Inoperative. | The LED lights up, when executing the command the LED turns off, the TV does not oscillate and returns to stand by condition. | Cold welding mainly on the power supply, regulators and vertical circuit. | Elisson Aragão |

It doesn't turn on. When we try several times, it turns on but is stuck on one channel, not accepting any commands from the CR or the panel. | Change eeprom|(24c04) and program setup parameters | ELETRONICA ESTSUDIER | |

Vertical with height deficiency (I noticed that the sides varied when the image changed) | I verified that the power supply +115 the 47/160 capacitor had low capacitance | By changing the vertical capacitor it was normalized | fernandocamarques |

CP14K42
|
It fires when it turns on then turns off (note all voltages are present at the moment it fires) | Defective vertical output (la7833) note there is no point in removing it from its place, the ap only works with it in place) | fernandocamarques | |

No plot and no sound | Tv lg flatron rp-29fa30a was without plot and without sound. when pressing the power button it produced an intermittent hiss...like tshhh.....tshhh.....in the tsh collector there was also an intermittent +b, varying between 110v and around 70v. It was possible to observe that there were some voltages originating in the fly-back secondary, quite reduced and also varying, but there was no voltage at the screen output, which indicated a defect in it. Replacing the fly-back with one from Brasalfa, the defect was resolved, but the weave was excessively wide. After checking that there were no damaged components in that circuit, it was enough to enter service mode and make the correction. (One way to enter the service mode of this device is to simultaneously press the menu keys on the remote and on the TV panel for + or - 10 seconds.) | littlecarlos | |

When turned on, the TV turns off in less than 2 seconds | I changed the processor. str6654, but it didn't solve it, it keeps turning off | Then I decided to replace the memory (24c04), it was shot and dropped, it didn't turn off but it remained file, it was the memory that was the defect | |
