Ticking noise from Aiwa compact cd system
Hi All
My compact Aiwa system (all-in-one CD / tape & tuner) has developed an annoying 'ticking' sound when it is playing CDs. If I was listening at normal levels I guess it wouldn't be such a problem - but the setup is used to provide low-level background music during spiritual healing sessions.... and it's a bit distracting The ticking seems to go away about 15 minutes into the CD - and seems common to all CDs - as in a mechanical sound rather than something on a particular cd. Any ideas ? I'm OK on general electronics but not clued up on these new-fangled CD devices g. This particular unit is probably 6 years old.... Thanks Adrian Suffolk UK |
Adrian,
Funny we just transfered our Aiwa LCX-100U to the kitchen because it kept skipping and needed to be reprogrammed each time to "repeat" during massage therapy sessions. It turned out the lens just needed to be cleaned. As to your problem I've had this happen before when either the spindle got pushed in too far (those that are press fit ) causing the CD to touch part of the mechanism or the shock mount got moved. Usually from being dropped. They are rubber grommets that mount the motor and would require some disassembly to get to. That it goes away after 15 min might be because the optical head is in a different position? BTW we replaced the Aiwa with a Sony CMT-EX1 we got on eBay and have been very happy with it. Richard |

So Adrian,
Is this a fast click click at the same speed that the CD is spinning and not in the speakers (something with the motor or drive) or a slower random click in the speakers (something possibly in the power supply) Took the Sharp apart - but couldn't see anything obviously disconnected inside - does everything it should but the flourescent display is blank... Is it a flourescent glowing display ( check voltage on the display module itself often marked on the pc board.) or back lit LCD display ( possible blown bulb) Richard |
