| curls <borskyc@yahoo.com>: Jun 03 09:52PM -0700 What a bunch of great information. Sorry I've missing in action here. I took it off, cleaned the lens again (and lots more times)... and it's kind of livable now. It plays often on first try, sometimes 1 or 2 more. Once in, with the next start, it often does a CHECK CD but then within a minute or two it starts playing. All music CDs played the 1st time. It played two homemade CD-Rs just fine, and two wouldn't play with many tries. So I don't play them much in the car anyway, and could copy them to CD+Rs if need be -- or get modern and get them onto a ipod or such device. So I'm stoked! I'm still tempted to do more but don't want to mess it up accidentally. I have another CD boombox that's broken, so I may try working on that, now that I have the courage. On this CD the possible additional fix seems to be turning over the player, and from the bottom taking out the tiny screw on the box that goes up and down the spirally thing (to give it a technical name). The other side of the box is the mirror. So I'd guess that opening it up (by unscrewing), will expose the mirror. And that since cleaning the lens helped, likely the mirror would make maybe even the rest of the difference. My worry is that there's adjustments that will get knocked out just by unscrewing that box. ...?? ---- Makeup applicators - hadn't thought about it, but that'd be much better than q-tips. Also I probably have some sponge-type paint brushes from the hardware store. Sam who set up this forum writes that CD cleaners can damage the player. It answered what I was wondering - how does anyone know how to build a brush close enough in distance and high for all the variety of CD players, to work? So very useful to hear the read experiences and feedback you all have had. I had tried one and got lucky that it didn't damage anything. |

That's quite a story :). Applies here and interesting that it looked clean on the outside, and inside it was that brown... |

As I'm reading, I will work harder next time (!!) to make sure I'm not buying a smoker's car that was fixed up well, so I can't smell it. There's only one givaway in this car, a slight grey mark up where a person would hold their hand out a window. When a detailer steamed the roof, he showed me on cloth that it had been a smoker's car. The 91% seems to have cleaned off the lens. It's not 100% working, but it's much much better. Though it was cleaning a tiny surface by rubbing it many times in different directions. Then thinking I was done and doing it a few more times later on. |

No Fry's near me. But Microcenter is like Fry's, and has it, turns out. Foam-tipped swabs - will have to keep an eye out now that I know they exist. I'm sure burning is cheaper for smaller runs. Can even be done at home by a starting artist musician (which is several of my albums.) |

Thanks for the link Ralph! I don't normally buy from Amazon so shipping adds up, but my sister buys there all the time, so I have her get select items for me. |

Or that water in 70% is needed to make the bugs go belly up (or blow up). I was thinking of asking on Freecycle for a thimbleful, if I decide I need it. I'd certainly offer if I'd bought a pricey bottle and someone asked. |

It moves up and down a spirally thing. I cleaned the circular glass button in the middle which I assume is the lens, including the edges. I couldn't get access from above and had to reach from the side from an opening in the casing. However, that box has a screw on the other side when I turn the player over. (It's one of the photos of bottom.) So I'm guessing the mirror glass is in there. Where exactly is the mirror in that link? In the second link, nothing is marked mirror. There are two flat squares that look like they'd be it. My worry is that there are adjustments, and they'll be messed up just by opening the box. Seems like it should be openable without damage, but I'd want to know it's usually not a problem to open the box. > My point is that the drive is NOT easily replaced. No clue on parts > but unless the CD drive mechanism can be identified, finding > replacement parts is going to be difficult. Yes, replacement parts would be hard to find unless a company lists them by car model. I did find a number of Mazda 3 radios on ebay. It's always risky that they didn't test them well, or who knows what. Some were cheap but the better feedback ones were over $100, and often $160 or so. Some cheap ones seemed to be because the faceplate was scratched which of course isn't a problem for me. So if I get too frustrated... that's my backup plan. > Read the repair faq section on "CD players in vehicles". I had before posting here.

| curls <borskyc@yahoo.com>: Jun 03 11:09PM -0700 - Sam's write up says there may not be a turning mirror, if there's enough vertical space to skip it. http://www.repairfaq.org/sam/cdfaq.htm#cdcompop - The pickup seems worse in hotter weather. Is there a logical reason for this? |
