UN40ES6500
|
When switching on, the relay hits and nothing else, without 13v and 140v power supply voltages. LEDs, with low pulses at these voltage points. | In this case the problem was 01 of the 4 Q9401 MOSFETs shorted, just change it and the problem was solved. | ALBERI F S | |

Does not turn on and without standbay, without 12 and 24 volts at the power supply | Cause r73 1k resistor open, just change it and the TV works again | The r73 in 1b that was open was replaced and the TV started working again. | eletronica cachoeira |

Philips 42pfl3403/78 stand by led blinks twice but does not turn on. | The TV turns on the stand by LED, accepts the power on command and after this command, press the channel + button when you can hear (very softly) the re1 relay engaging. At this moment, tsound was only a voltage of 3.3 volts because this relay had a bad internal contact. I dismantled the relay (it can be dismantled) and saw that the terminals were very far apart and that's why it armed but did not conduct (and the docking sound was very low). All I had to do was clean and twist it to bring the contacts closer together and the TV started working again. normally. | littlecarlos | |

TV does not turn on, with loud buzzing/whistling noise | Horizontal output transistor q404 (2sd1427) shorted. When removing it and turning on the TV, the horizontal frequency reached more than 24kHz on the transistor, causing the component to burn out. | Following the tip from colleague moraes sptv campinas, the capacitor c408 (10μF 16v) was altered. Replacing the capacitor and horizontal output transistor solved the problem and the TV started working normally again. | Rgs011 |

TV doesn't turn on, standby LED lights up very weakly. | The 5v line on the standby was only 2v, as was the 3.3v line that comes out of the ic1201 regulator and powers the computer. | Zener diode d1140 (5.6v 0.5w) shorted, killing the 3.3v line that powers the computer. By replacing this diode, the TV turned on again. | Rgs011 |

RP-21FE85G
|
Horizontal output transistor q402 (tt2170) shorted, fusistor fr403 (1.2ohms 1w) open. | Cold solder on the horizontal output transformer t403, causing the horizontal frequency not to reach the horizontal output transistor, burning it. | Re-solder the transformer, install another horizontal output transistor and another fuser. I installed some tt2170, they all burned instantly and opened the fusistor too. probably counterfeit transistors. I replaced the tt2170 with a bu2520dx, it didn't burn anymore. As the bu2520dx is bigger than the tt2170, I had to make a hole in the heatsink to adapt it, but it worked perfectly. | Rgs011 |

Locking functions and then I crash on the logo | Update I downloaded from the oac website | After the update, it works, but tsound was a leak in the corner of the TV and a color spectrum! I went into service mode and set the TV to factory mode and it solved everything! press the menu key after 1999 and the back key! ok just on reservation! After a while, 1 minute maximum, turn the TV off and on! | Celoozs |
