Does not turn on, nor does the stand by LED | Measure n805 middle pin with the negative housing, if it is shorted it was already a processor. If it's not shorted, tsound's a solution! | Replace nw910 and nw955 both are shorted primary and secondary power supply sector. I hope I helped!! | Maike Sorriso-MT |

The CD drawer closes and locks, sometimes it closes correctly and spacer discs fall out and lock the mechanics. | 1.8 centimeter spring that is between a gear and the support that holds the motor belt ends of the flagged flag with a length below 1.8 centimeters | Carefully stretch the spring until it reaches 1.8 centimeters, no less than 18 centimeters. Without this spring, the mechanics won't work, so don't damage or lose it. | |

Customer reported that the sound was lower than normal, I asked to bring the speakers for an evaluation... | Toasted coils, suspension removed from the speaker cone, speaker wires bare, probably connecting more speakers in parallel and lowering the impedance, total damage, almost burning the amplifier. | Whenever I carry out maintenance on these powerful devices (mainly Sony and Aiwa) and with owners who abuse the volume, ask to bring the boxes, these I will have the coils replaced from 4Ω to 8Ω, and add a 10r x 10w resistor to the tweeters to avoid burning out altogether. | Trendset |

Volume lowering on its own | The device worked normally, after a while, it started to lower the volume by itself, I suspected the microswitches, but they weren't them, I replaced the ci402 (Toshiba tc9153), I also suspected the remote control module, I disconnected the down, up, mute and 12hz wires, It remained the same, I started searching, and found the culprits, tc401 and 402 (bc547) | Ci402 (tc9153), and the t401 and 402 (bc547), I ask anyone who has the schematic for this version with remote control, to post it in the group, and the modification to deactivate this module. | Trendset |

Turn on the logo and turn off the backlight, sound is normal. | Tsound is a way to disable the protection of the ssl100sn ci, to do so, place a resistor (1k) from pin 2 to ground, if that doesn't help, also place a resistor (1k) from pin 8 to ground. | EC |
