Does not load. | If the LED flashes quickly: secondary defect. If the LED flashes alternating between fast and reading: primary defect. | Defect in the primary: check if tsound is voltage in the primary, if so, it is normally the ci smps, to test, place a 100r resistor on the LED of your photocoupler (secondary) and check if the power supply oscillates, if not, replace uc3845b. secondary defect: LED flashing quickly: check if the battery connector is ok and replace all the p-channel mosfets (k84 = bss84) that read the battery cells. | DSSTECH |

Vertical is closed when turned on and goes into protection | After checking the vertical output, I diagnosed problems with the reg. 9v | I found res. 10k r 823 open, connected pin 4 ic 805. | Imagem |

TV turns on the sound of the channel and image in the background, but the blacklith does not turn on | Short in backlight circuit | Replace ub1 (mp4010) db1, db2 (sk320u) db3 (15v zener) qb1 (mdd14n25) rb9, rb8, rb7 and rb6 (0.33r0.33r0.33r and 0.51r all resistors in parallel) | Felipe Francisco (Gov.

The TV turns on normally and everything is normal, except for a strange black vertical stripe in the corner of the image (as if electrical tape had been placed on the screen). | Change "micro" the ci does everything on the tv. | Replace the same. (edfesom:) | EDFESOM |

TV stopped, won't turn on after a while. | Shorted capacitor, on the 5v line. c217 of 470uf/16v close to the microprocessor. | After changing the TV ok. | George Pontes |

It didn't turn on at all, it just blinked slightly, the standby hit the relay, and it turned off almost instantly, leaving the primary capacitor charged. | (q601) the famous tl431 just change and be happy. | Replace the same. (edfesom:) | EDFESOM |

Turns on the logo appears and turns off. | Defective LED bars! LED burned out or shorted | This TV uses 3 bars in parallel with 5 6v LEDs on each bar, so each bar only supports 30v. in my case the power supply was sending 32.5v! 1st replace the LEDs or bars. 2nd lower the voltage on the LEDs to 29.2v by removing the 2r2 smd resistors (rb13, rb14) good luck. | EvandoViana |

It does not tune, it is a clear failure of the tuner | The problem is that tsound is no regular replacement for this "dt5-bf18d" tuner, sound you have to go to the official service, which can take up to 6 or 8 months to wait, I have been able to repair it by changing the internal oscillator crystal that It has a "sy4136t" I have put a 4mhz one from another Philips tuner and it works, you can put a 4.43mhz one (the chroma oscillator) to test, although the displaced stations will appear.indigena | Pablo | |

It works correctly but if we turn it off from the remote control, the power supply collapses and we can no longer turn it on from the remote control until we turn it off and on from the switch. | Change indigenous cosmo 1000-817-821c optocoupler | Pablo | |

Turns off after about 30 minutes. | Voltage regulator n803 (1117-1.5v) which is next to the processor, dropping voltage on the in pin. As it heats up, the voltage drops and heats up the resistors r831 and r832 (both 15r/2w). | I turned off the LED chain to prevent it from returning. | Eletrônica R-Tec |

Dark screen without backlight | Burned out leds | Replace all the rulers or burned and unburned LEDs due to wear. replace the value of r 9110 d3 1r5 to 3r7 to reduce the current and voltage on the LEDs in order to extend the useful life of the LEDs | marco.32 |
