Adjusting a skipping CD player - ?
Hello,
I thought I'd ask here before converting my CD player into an inverse AIRFIX lifesize model. My about 10 y.o. SONY har recently begun misbehaving, with progressively worse skipping primarily when playing newish (Audio) CDs, the first three (innermost) tracks mostly affected. Last week I opened the cabinet for the first time since it was assembled, discovering a very clean inside, with whitish grease still neatly lubricating the interacting surfaces of the disk transport mechanism. Only sign indicating use was on the inside of the cover above the transformator, where a light deposit could be wiped off. I cleaned the laser disk gently with ethanol, but found nothing else I obviously could do anything with. Subjectively, I imagine a slight improvement in the clarity of music played post-cleaning (but this may be a placebo-like effect). The skipping continued as before. Today I consulted a local SONY shop, who informed they'd be happy to take it in and look at it (£42). If they could do anything to it they would charge per hour (£36) spent fiddling with it. If they decided they could do nothing with, it they would generously deduct the "staring fee" against the purchase price of a new unit from them. Needless to say, I left immediately. Does anyone recognise this behaviour as signs of increasing misalignment (or other correctable deviations from normalty) ? If this is the case, can anyone recommend an independent workshop which might adjust the player? Or alternatively, does anyone know whether this may be done DIY-wise; thus instructions of how to do it would be very much appreciated (very often, specialist servicing jobs are surprisingly simple!). Thanks for any input! (And whilst typing the above, I've listened to one of my favourite recordings, purchased the same year as the player - without any skipping) Cheers, -- T Sandvik // to send e-mail, remove clothes |

Make sure all sliding parts aren't sticking at the end of their range. And make sure any rubber belts are clean and grease-free. Apart from that, there's not much you can do without technical skills and equipment. And if you had those, you wouldn't be asking here :-) Is it a particularly wonderful player? The current sub-£100 Sonys are really very good. |

I found a CD player whose lens had fallen off and realigned it. If I costed my time, I could have bought a nice, new, non-Sony one. :-) When did Sony stop making CD players that cause headaches? It must have been about ten years ago. Roger. |

I think that authorized repair services have three advantage over independent ones. First, they have an easier access to custom parts, like ROMS or transformers. Second, having seen more models of the same type and brand they could recognize some common pitfalls. Third, an authorized service has to meet some standards. Which should give them an advantage over independent specialists, in being able to spot the problem in four minutes, and if possible, fix it in another five. Instead, they screw it all up by having their management making them charge 1 h for each of the mentioned activities; half aiming at "helping" the customer to decide to buy a new box of their brand instead. They loose me as a customer, because of their attitude, even if their products are good. Anyway, try to search sci.electronics.repair FAQS: there is some advice on servicing CD players. Just found it - will have a closer look. THanks - -- T Sandvik // to send e-mail, remove clothes |

I think that authorized repair services have three advantage over independent ones. First, they have an easier access to custom parts, like ROMS or transformers.

The copy appeared to play slightly better wrt skipping, but was more noicy (sudden "bursts"), and thus not a useful copy. A hallmark of a mediocre CDRW, or blank disks ? (unfortunately didn't check details) This seems to indicate that the reflectivity of the disc is a factor. Try cleaning the objective lens with a cotton bud. |

Although I have virtually no electronics experience, and will probably get
slammed for what I'm about to say, I've fixed three or four "skipping" cd players that were destined for the trash by doing the following: When you open up the lid of your cd player and slide the tray out, take a look on the circuit board for some adjustable potentiometers. Take some white out and mark these. Then take one and move it incrementally (i.e. 1/16th turn) in one direction and then see if your cd player still skips. Make sure you're keeping notes. If you don't get a change, put it back to its original position and try another pot. As I say, I've fixed a few cd players doing this (Technics, Sony and Pioneer) and it really wasn't that difficult and the way I figured it was, if I ruined it, I would be no worse off than having a cd player that didn't work properly anyway. BTW Everyone else's advice to grease the tracks, check the bands, etc., is a given and should be checked first. Good Luck. Spiderant. "ts" wrote in message ... Hello, I thought I'd ask here before converting my CD player into an inverse AIRFIX lifesize model. My about 10 y.o. SONY har recently begun misbehaving, with progressively worse skipping primarily when playing newish (Audio) CDs, the first three (innermost) tracks mostly affected. Last week I opened the cabinet for the first time since it was assembled, discovering a very clean inside, with whitish grease still neatly lubricating the interacting surfaces of the disk transport mechanism. Only sign indicating use was on the inside of the cover above the transformator, where a light deposit could be wiped off. I cleaned the laser disk gently with ethanol, but found nothing else I obviously could do anything with. Subjectively, I imagine a slight improvement in the clarity of music played post-cleaning (but this may be a placebo-like effect). The skipping continued as before. Today I consulted a local SONY shop, who informed they'd be happy to take it in and look at it (£42). If they could do anything to it they would charge per hour (£36) spent fiddling with it. If they decided they could do nothing with, it they would generously deduct the "staring fee" against the purchase price of a new unit from them. Needless to say, I left immediately. Does anyone recognise this behaviour as signs of increasing misalignment (or other correctable deviations from normalty) ? If this is the case, can anyone recommend an independent workshop which might adjust the player? Or alternatively, does anyone know whether this may be done DIY-wise; thus instructions of how to do it would be very much appreciated (very often, specialist servicing jobs are surprisingly simple!). Thanks for any input! (And whilst typing the above, I've listened to one of my favourite recordings, purchased the same year as the player - without any skipping) Cheers, -- T Sandvik // to send e-mail, remove clothes |

You can't run a business on the basis of "That's OK - it was an easy one. Bung me a fiver!". Disagree. I tend to return to shops that previously have given good, non-rip-off advice, and have deliberately purchased the most of my expensive home-audio items from them. -- T Sandvik // to send e-mail, remove clothes |
