Device arrived with audio and image out of tune, after a fall | After analyzing the components of the board, I verified that tsound was a defect in the coil l6 responsible for the image and the only way to tune it is by moving the coil with it turned on, after programming it on a channel, of course, the hiss was caused by the inductor l2 and it didn't work. tuning, when changing the audio it was normal for a few minutes and started to hiss, then, as the induction of l2 is equivalent to 3.3uh, so I wound a coil with an inductance of 3.37 and the audio returned to normal | Make the two coils and tune. at l2 tsound are 42 turns of 26 enameled wire with an air core the diameter of a toothpick battery. do this and run for the hug! | Jailson Lima |

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 |
