AIWA CD player early failure
I own an AIWA CD player (TZ92), 13 years old. In this time I have used
it about 50 hours (it was in my summer house), and I've changed the laser two times, the first 6 years ago and the second this week. I don't want to throw it, as it is part of a chain. My questions a - The life of the laser is related to working hours or installed hours? - This short life, is normal? - Is there any method for lengthening the life? -- Regards Miguel Giménez |

is it just dirty?
I fix most CD players simply by carefully cleaning the lense on the laser with a Q tip and alcohol.... checkout the Sam Goldwasser sites.... Mark |

Mark The first time I did clean it, but without success. This second time I opened it, the lens looked clean, but didn't clean it. I sent it to Aiwa and they told me that it wasn't dirty, but faulty (may be they lied me). Thank you for pointing me to Goldwasser's. -- Regards Miguel Giménez |

Gently move and flex the cable to the laser a few times then try it again. If it works, replace the cable. |

It doesn't wear when it isn't in use, and it doesn't simply go bad sitting on the shelf as can happen with electrolytic capacitors. Lifespans vary with makes/models. It's potluck, as some higher-priced models are found to have shorter laser lifespans (on average) than some cheaper models. There is no technique for increasing a laser's lifespan. If you were to reduce the diode's working current, it wouldn't track the disc properly. |

Often it`s the 45 degree mirror that`s dusty or tarnished, dificult, often impossible to clean effectively.
