Usually, a CD or DVD that skips or does not play properly is dirty. Fingerprints, dust, dirt, and hair can interfere with the laser reading the disc causing it to skip or have other minor glitches in specific parts of the disc. Computer cleaning information and steps.
How to replace the laser pick-up assembly of your CD player
Below are various reasons why a CD or DVD may skip during use.
Dirty CD
Usually, a CD or DVD that is skipping or not playing correctly is dirty. Fingerprints, dust, dirt, and hair can interfere with the laser’s ability to read the disc and cause cracks or other minor glitches in certain parts of the disc.
Incorrect burning or copying of CD or DVD
If the skipping CD or DVD was copied (burned), errors may have occurred during the burning process. If this is the case, these errors can cause the disc to skip when played. To ensure that this is not the problem, try recreating the CD or DVD again.
Dirty CD-ROM or other drive
A CD or DVD drive can also become dirty from dust, dirt, or hair getting into the drive. If you have multiple CDs or DVDs skipping or other reading errors, the drive may be dirty.
Software does not play disc correctly
If you’re using a media player to listen to an audio CD or DVD, try a different program and see if that works. If you have access to another computer, car audio system or TV DVD player, test the CD or DVD in that system as well.
CD or DVD scratched or otherwise damaged
If the CD or DVD has significant scratches or cracks, it may cause the CD or DVD to skip, stop playing, or not play. If you’ve tried all of the suggestions above and are only having trouble with a single disc, the disc is likely defective and should be replaced.
Bad drive
If you encounter skipping or other random read errors on several different CDs or DVDs, chances are the drive itself is defective and should be replaced.
How does a laser work in a CD player?
The fundamental job of the CD player is to focus the laser on the track of bumps. The laser beam passes through the polycarbonate layer, reflects off the aluminum layer and hits an opto-electronic device that detects changes in light.
How to replace the laser pick-up assembly of your CD player
As explained in How analog and digital recordings work, a CD can store up to 74 minutes of music, so the total amount of digital data that needs to be stored on a CD is:
44,100 samples/channel/second x 2 bytes/sample x 2 channels x 74 minutes x 60 seconds/minute = 783,216,000 bytes
advertisement
To fit more than 783 megabytes (MB) onto a disc just 4.8 inches (12 cm) in diameter, the individual bytes have to be very small. When you examine the physical structure of a CD, you can begin to understand how small these bytes are.
A CD is a fairly simple piece of plastic, about four-hundredths (4/100ths) of an inch (1.2 mm) thick. The bulk of a CD is an injection molded piece of clear polycarbonate plastic. During manufacture, this plastic is imprinted with microscopic bumps arranged as a single, continuous, extremely long spiral data track. We’ll get back to the bumps in a moment. Once the clear piece of polycarbonate is formed, a thin, reflective layer of aluminum is sputtered onto the disc, covering the bumps. Then a thin layer of acrylic is sprayed over the aluminum to protect it. The label is then printed onto the acrylic. A cross-section of a complete CD (not to scale) looks like this:
Can CD players be repaired?
In fact, there is little you can do besides clean the CDs, clean the machine, or replace cords. Just about everything else should be turned over to an electronics technician. You can use a CD repair kit, available where CDs are sold, to polish out scratches on the underside of the disc.
How to replace the laser pick-up assembly of your CD player
How does a CD player work?
A CD player is an electronic device powered by a universal motor that spins a flat plastic disk etched with a digital code that represents specific sounds. As the player spins the CD at high speed, the audio track – less than the width of a human hair – is read by a laser beam, which is used to create an electrical stereo audio signal. This signal goes to an amplifier and speakers or headphones to play the music presented on the CD.
What can go wrong with a CD player?
CD players either work or they don’t. The third option is that they work but the sound skips – which is usually caused by a dirty or damaged disc rather than the player. CD players have few moving parts and are mostly trouble-free. In fact, there’s little you can do other than clean the discs, clean the device, or swap out the cables. Almost everything else should be left to an electronics engineer.
Fix-It Tip You can use a CD repair kit, available wherever CDs are sold, to buff out scratches on the underside of the disc.
How can I identify a CD player problem?
CD player problems are usually obvious, but the solutions may not be.
If a CD player doesn’t work at all, make sure the power is on at the outlet. Check the power cord and replace if necessary; Remove the case and check the fuse. Test the on-off switch and replace if necessary.
If a CD player works but makes no sound, check the connections to the stereo and clean the clear plastic reading lens.
If a CD player is skipping, check that the CD itself is not scratched or dirty.
If a CD player tray does not open or close properly, check the belt for dirt or wear and the tray for misalignment (remove, clean, lubricate, and reseat).
If the sound from a CD player is distorted, check and clean dirty output jacks.
Fix-It Tip CD players and other electronic devices are dust magnets. Thoroughly clean the inside of these devices every month with canned compressed air or a vacuum cleaner.
What do I need for a CD player repair?
You can find CD cleaners, canned compressed air, and other tools and parts at electronics stores or even larger discount stores. Replacement parts must come from the manufacturer or aftermarket suppliers. Here are some of the tools and materials you may need:
screwdriver
multimeter
Canned air or soft brush
Foam swabs or camera lens cloth
lens cleaning liquid
Clean, dust-free cloth
White lithium grease
tweezers
cotton gloves
CD cleaning fluid or denatured alcohol
What are the CD player repair steps?
The four main repairs you can make to a CD player include cleaning a CD, cleaning the lens, cleaning the tray, and replacing the tray motor. Let’s take a look at each:
Cleaning a disc:
Hold the disc by the hub and outside edges. (The music data is on the back or bottom of the disc.) Blow dust off the underside with a can of compressed air. Clean dirt and fingerprints with a lint-free cloth dampened with CD cleaning fluid or denatured alcohol, all available at electronics stores. Wipe outwards from the center (no circular motions).
Clean the CD player lens:
To access the lens in a single-play device, remove the case and gently lift the hold-down clamp to reveal the lens. To remove the lens in a carousel player, remove the player case and unscrew the bracket that attaches to the top of the carousel, then lift the bracket off. Remove dust with compressed air or a soft brush. If necessary, use a cotton swab moistened with lens fluid or a camera lens cloth (not a glasses cleaning cloth).
Service the disc tray and belt of a single-play CD unit:
Open the case by removing the screws on the outside of the case and remove anything blocking the tray. Press the open-close control to extend the tray and disconnect the device. To remove the front of the clip-on tray, support the tray and slide the panel aside. Disconnect all cables connecting the front panel to the interior. Remove the screws that secure the faceplate and gently pry it off. If the plate won’t move, look underneath for clips or extra screws. Lift off the hold-down clip, screw, or spring on top of the disc tray. Gently pull the tray out of the player. Clean the runner and the guides with a swab moistened with denatured alcohol. Lightly lubricate the bowl with white lithium grease. Remove the belt to inspect for dirt, water, or damage. Avoid touching the strap with your fingers. Use tweezers or wear cotton gloves. Clean the belt with a lint-free cloth dampened with denatured alcohol. Replace belt if damaged.
Service CD Player Tray Motor:
Unplug the player and test the motor. A dirty motor connector can cause the tray to work intermittently. To clean the motor connector, unplug it and spray it with electrical contact cleaner. Then plug and unplug the device repeatedly to check the contact. To remove the motor, press the end of each clip or ball with a finger and lift up. To replace the motor, carefully remove the drive belt with tweezers or a gloved hand, and then lift the motor from its mount.

Do CD Player Lasers degrade or just suddenly fail?
Do CD player lasers degrade or just suddenly fail?
Wondering how long the quality cd player can last?
Well I guess it all depends on the implementation whether it’s CDP or a digital music server, but all things being equal I actually think a well designed music server has the potential to have a better sound. I’m thinking of starting a thread where people can talk about the architecture and why one is better than the other. Personally I think a music server is actually a better architecture if it has a good design.
With all due respect, many receivers for the mass market do not have the best sound. They messed up the input stage, power stage, preamp and DAC and I suspect they have noise everywhere. Also, most of them don’t have a very good DAC and their power amp isn’t very good either.
But anyway, if you can afford what you’re telling me, NAIM, Cyrus and some of the UK audio manufacturers make very good music servers.
How to replace the laser pick-up assembly of your CD player
How to replace your CD player’s laser pickup unit
Ah! Repairing CD Players… If you have experience modifying your CDP, repairing seems like an extension. Or shouldn’t that be a requirement? Nonetheless, most repairs to CDP simply consist of replacing the laser pickup assembly. You see, over time even the most powerful laser dies out. And a CDP without his laser is like a Diyer without his soldering iron, Austin Powers without his mojo…
So your friendly diyer here will show you how to alter/replace this flimsy little construction that will cost you a bomb to fix at most repair shops. I think you also know that your kind diyer will draw the wrath of many garages. A hit squad could be sent out to pin me down very soon. Would you send me some $$ as compensation for giving up so much?
OK, enough talking. 10 more pages won’t even see you get your butt up, what less to write me a check?
It would be great if I could show the Marantz CD63 as it’s the CDP I get most of the time for repairs. Since it has been discontinued for a number of years and due to its immense popularity at the time, it is no wonder that so many CD63s need repairing. Unfortunately not this time… So I had to present the Marantz CD46. Hopefully you’re “bright enough” to adapt what I have here to your own CDP. Well I bought this CD46 when I was a student in the US. Then it cost me $200. 6 years later it gave up the ghost. Can’t read CDs anymore. If you haven’t dared to hack the CDP yet, chances are your laser pickup assembly has gone to CD heaven. Um, before I go any further I assume you know how to open your CDP?
Here is the inside view. Very spartan, in fact half of the CDP is “air” so I paid USD 100 for “air”! But if you’re a die-hard DIYer, you should be smiling with delight, because the possibilities of driving this CDP are enormous! do i have to start Add a clock, a tube power amp, blah blah blah… You could even hook up a 1W amp with 5842 tubes. How about a “high end” mini compo?
To access the laser pickup, you need to disassemble the entire transport. So away with the tray! A gentle push should do the trick but some models have small gears underneath so please check your CDP.
At the maximum you can no longer pull the tray out because there is this little latch holding it back. See previous picture again to see the latch in detail. Use a flathead screwdriver to slide this latch aside.
Once you’ve got the tray out, it should be relatively easy to remove the transport. Disconnect those wires, loosen those screws. However, be careful. This is the most important step as you will need to pay attention to how your transport is assembled as you will need to RESET it later. Yes! Dismantling is easy! But resetting is always troublesome especially if you are not careful now. Since this is specific to each model, it makes no sense for me to show you pictures. Just study the construction, okay? On the CD46, the wires circled in green are connected to the transport. With the CD46 I had to remove both as the transport is attached to the board. However, on some models they are separate. So study your CDP, okay?
Another reason why you should consider modding a CD46. The DAC chip is the TDA1545A. Miniaturized CMOS version of the TDA1541. The lines connected to pins 1/2/3 are the I2S lines… Non-oversampling!
There is a flex cable that connects the laser pickup to the board and it is located just below the transport. Your CDP might be different, but be careful… These things are really flimsy. To disconnect, use your thumb and forefinger to gently push the white connector toward the ribbon cable.
With the transport section now side by side, we have the new pick-up assembly on the right. And left in the transport present. Do you think you can trade them?
Well, you have to take it out first. It’s really easy as all you have to do is “push it out”. I know it doesn’t make sense now, but if you study your naked transport you should be able to figure that out. Note that the new pickup’s ribbon cable has a metal termination. Please leave it there until you are ready to connect it to its white connector. You don’t want it happily picking up ESD. Actually I should do all this on an ESD safe mat…
You should now have the pickup in its holder. To remove it from its mount, gently pry these plastic springs out with a flat head. Ditto when assembling.
It’s a good idea to grease your new pickup assembly right now, just before soldering the wires. Be an adult and use it carefully. Just the plastic bearings and the chrome shaft please. It is best to use lithium-based grease. asking around
That’s easy. They’re just swapping parts, so don’t try to be smart and wire it up some other way. Follow the original device closely! To reduce the chance of soldering wrong wires, desolder/solder one at a time. If you desoldered a few and forgot which wire goes where, you have only yourself to blame… After you’re done soldering, put it back in its holder and slide it back into place .
In order! New assembly available! Now all I was thinking about was using these ESD sheets. Hmm… Um, just before you put the transporter back together it’s a good idea to lubricate all the moving parts.
Reassemble everything… Again, be careful with the flex cable. Make sure you get a good lock here.
Nearly! Be extra careful here. Make sure that all moving parts can still move freely. If you have an extra screw…
After connecting all the necessary cables that you pulled out earlier, you can test it. Turn on the CDP and it should say “No Disc”. Put in a CD you hate the most (preferably audiophile). The CD should spin clockwise and be able to read the Table of Contents (TOC). In case you’re wondering what the table of contents is, well, information like how many tracks, how many minutes of sonic heaven/hell this CD contains…
If it reads the table of contents, you’re almost free! Go to “Play”! If the table of contents cannot be read, check any broken/missing connections. If the CD spins counterclockwise, you’re in trouble. Either the replacement pickup is a dud or you screwed up…
I hope I haven’t scared you yet. Have fun! Finally I would like to thank BS Lee as he was the one who showed me how to fix the CD63. Many thanks!
