Some panel functions do not work, and when they do, it takes time to process the desired functions such as play, changing tracks, stopping, changing music folders on the pendriver | Faulty (47k) smd resistors and altered function panel touch keys | Check and replace the resistors that are altered, they are on the line and interconnected with the touch switches on the device panel sound they are (r48,r44,r52,r45,r49,r53,r56,r46,r54,r57) and the cellars touch( sw1,5,2,6,9,13,11,10,14,15,3,7,16,17), check and replace if these components are replaced, because if they replace the device will have the crazy functions, it takes time to respond to the given command | rubertan |

Turns on and off, in the av, it doesn't turn off only in the rf | See resistor 3450, 27k on the 33v line. | See resistor 3450, 27k on the 33v line. from varicap | DJ PITUKA |

Does not turn on power supply beeping and a tic tic tic | Shorted horizontal output (bu4508dx), capacitor c630 of 47ufx160v exhausted and bad fly back bsc29-3807d was replaced by a bsc25-n1571 and the tv started working normally again | Carlão | |

Turns on the panel LEDs, but with no function and the display is off and tsound is no audio | Shorted smd diode d3 is next to coil l5 of diode d7 and resistor r18 | At first I was suspicious of the microprocessor but it wasn't checking the power supply PCI and it was normal, then I went to the mother PCI checking the components I found this diode short I saw that it wasn't a zener but a rectification diode, I looked for its diagram on the internet and it didn't work. I found it, I decided to put a common diode in its place (in4007) the device even turned on and worked, but after a short time in operation its panel started to weaken, I noticed that the diode I had placed was overheating, I turned it off immediately, I stopped To think about it, I decided to put another diode in its place, but with a high switching speed, like the ones used in TVs that come out of the flyback and feed the vertical output, for example, I put one of those from a TV and the device was zero, it worked normally, I left it for a long time under test (note the diode that I removed from the chassis of a scrap TV, its code is tvr10g) | rubertan |

Device works normally, suddenly turns off and stays in demo mode (demo mode) | Panel contact key with low conduction or altered, place the analog multimeter on scale x10, remove the key from the PCI and test it on that scale and see if it conducts a little without pressing it, if it does, replace it with another one, If it is normal, remove all the others from the PCI and do the same test, sometimes some of them will be altered | Check it out, these tricks are a lot of mistakes, as they replace and the device goes crazy, they are these (1405, 1406, 1408, 1424, 1426, 1421, 1420, 1422, 1423, 1419, 1418, 1416, 1417, 1411, 1410, 1415 , 1412, 1413, 1414), front panel sw switches | rubertan |

Does not turn on, no standby | 1n4148 diode open, brown glue on it caused it to oxidize and open it, when I removed it from the PCI it broke in half | Replace it (d723) it is positioned next to the capacitor (c796) and the resistors (r805, r806) | rubertan |

Without audio CD does not work and carousel drawer does not open | Altered diodes on the main PCI, these little rascals alter their conduction and the voltage passing through them drops by half or completely resets if you test them on the PCI with the analogue multimeter, some of them will be altered, but for a more guaranteed service it is preferable to change them all, If you touch the soldering iron to one of its terminals, they will start to conduct and the device will work, be careful, don't trust, change them all | These are these little rascals, they are on the main PCI wsound the power audio ci is located, sound they are (d746, d745, d744, d743, d742, d741, d740, d748) | rubertan |

No audio cd drawer doesn't work | Diodes connected in series changed together with regulator ic702 (ka7812) | Replace these diodes as they alter their conduction, if you test them on the PCI with the analog multimeter some of them will be damaged but | rubertan |

Red LED flashes but nothing turns on | C.i of 8 terminals in position 7800 below the electrolytic 2804 of 100x16 | C.i broke and that's why I couldn't identify the code, I took another one from a scrap card. | |

Does not come out of standby | Removing the power supply connector in socket p22 on the main board or on the power supply and replacing it again with the power cable connected, then it works, serves the control and everything else. If you remove the socket from the mains, you return to the same problem and do not respond to any command. | Capacitor c474 de 4,7mf/16v | Helio Eletrônica |
