Image disabled horizontally and vertically closed power supply oscillating | Capacitor c 817 of 473nf dry | Replace with 1μF 400v | ELETRONICA COLARES |
| PANASONIC |
TC20A12
|
After 1 minute it turns off and turns on again | D1105 shorted (dz7.5v) | Note: heating IC 1202 and IC 851 | vagnernardes |

TC29Z99L

556 diode shorted out, replaced, the TV started working again, but with excess width and cushion effect. Tsound's no point in trying to fix it using service mode. (This was really hard to solve, it took me 3 weeks researching!) | The smd transistor q701 that makes the pincushion amplifier, even when measuring normally, was bad and the resistor at its gate terminal was altered (the transistor is 2sk2099 and the r is 64 r) | alexsts | |

29KL25
|
This TV arrived at the workshop with normal sound but with a horizontal scratch | Checking the circuit I found cap c 563 330k 250v as I didn't find the same value I associated 4 of 100k | And defect resolved. | BF.COLATINO |

TV20A10
|
When turned on, the protection is activated. Tsound is no sound and no image. | Diode d402 shorted at the vertical output. | Rubens | |

14RM15L
|
This TV was completely stopped and when I opened it and turned it on, I noticed that the r-850 resistor was getting very hot, causing the q-850 to short out, but when I replaced it, everything remained the same, not even the std-by LED lit up. | All vertical voltages are present except pin 5 which has 0v and should have 28v and pin 6 which has 15v and according to the service manual it should have 29v. | Solved, it was the micro | BF.COLATINO |

TC20C20
|
This TV has no color, I checked capacitors near the do-it-all, resistors and everything, and it didn't solve it | Solved, it was the tda4665. | BF.COLATNO | |

I received this TV when it was stopped, and when I turned it on I noticed that the r-850 resistor was getting very hot. | The cause was the transistor q-850 shorted, I replaced this tr and even so the device still stopped, I noticed that in the lamp in series the device showed consumption and I found the zener d-883 shorted, after replacing the device the LED turned on std-by and it started to work on and off and with the vertical closed, I tested the entire vertical circuit and even replaced the vertical output but the defect persisted.. | Resolved, it was the micro. | BF.COLATNO |

29KL04
|
Doesn't start | Horizontal output shorted. When replacing it with another one, it heated up too quickly to the point of burning your finger if left standing on top of it. Checking a little more, I found d 556 with a leak. | Just replaced it and stopped testing and everything was fine. | BF.COLATINO |

TC29A11
BR2 |
Turns off a few seconds after power on | X-ray acting | In this case the defect was in the vertical ci, it activated the x-ray protection, pin 36 of IC 601. This ci (vertical) was replaced and the TV started working normally again | dias |
