The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them. If you have the proper tools and equipment, the first thing to look at is the RF pattern of the unit while its playing. It should be a sharp and clear pattern. If it's dull and smeared, then the laser could be weak.
Also, in these units are very critical alignments called the focus/tracking gains and offsets. When these alignments are off, it can often cause intermittent troubles. As the unit ages and parts change value, so do these alignments, and will need to be checked. In my time as service technician repairing DVD/CD players, 65% of the laser pick-up assembles I have tested were good and only needed a small adjustment. Today's technology makes it unfeasible for a shop to hook up a DVD/CD player, and even some recorders, to their equipment and make these adjustments because of the cost involved.


To clean the lens you must use very little pressure. Take a cotton swab and barely moisten it with plain, non-scented, or oily type alcohol. In a swirling motion, very gently rub the lens until you’ve covered it entirely. Then repeat using the dry end.
If the cleaning didn’t help, don’t despair just yet. You can see if there’s a problem elsewhere in the unit by using a few simple tricks and tips.
First thing you want to see if the unit’s laser is in good working order. This method isn’t foolproof, but most of the time works admirably. When you insert a disc, see if you can look up underneath where the disc sits on the turntable. Observe the laser lens going up and down. If the lens is trying to focus, that’s good! After a few seconds of the lens trying to focus, the platter should start to spin. On almost every CD/DVD unit I've encountered, the unit won't spin unless the laser has properly focused on the surface of the disc. If the unit spins up and and then shuts down, you should check and make sure the laser pick-up assembly slider mechanism is working without any obstructions and that the small chrome rail that it slides on is slightly greased. Don’t go overboard with the grease though, as too much can cause all sorts of problems

Hope it may help you;

Regards,

The E01 is a mechanism error. Basically the unit is telling you that the cassette is tuck (like you don't know that already!!). What has happened is that the mechanism has jammed. No cleaning of the lens or rails or alignment will fix this. This is strictly a mechanical problem. Sometimes you can open up the unit and see what has jammed and clear it. I have seen CDs that have not seated in the carriers correctly cause this. If you can move the CD enough to seat properly, it may clear itself. If n ot, than the unit must be dis-assembled and rebuilt. This involves "re-timing" the gearing inside that may require a service manual.

The botom line is that you will need to examine the mechanism for any obvious jam and try to clear it. If you don't feel confident in doing this, please do not attempt it. You would be better off bringing the unit to a repair facility.

I bought a nice jensen home audio system with 3 cd changer belt drive turntable and dual cassette. When i got it home i tried to play a cd and it wont read any cd past track 7 please help


If this is an old set then it is possible that the optical head is weak, the servo is faulty or the mechanism is jammed.
So open and clean head, check to see if the optical head moves well into the mechanism if not clean the gears.
If none of these work the optical head is faulty.
replace with correct procedure.

CD player won't work


Firstly is it burnt or factory cd? Most factory cd players won't play a burnt disk.
If you have a store-made cd and it is not reading that, then the lens inside the player is dirty and needs to be blown out with a can of "airduster"

We have the RCA RS2767i Home Stereo with 5-disc changer and ipod dock. The CD Tray won't eject or shuffle...everything else works fine. It seems the disc tray isn't responding to anything. We read in the...


Let me respond with a possible solution although I'd bet that both of you already tried these.

The reason I checked into this is because I'm looking for a new mini system. I happen to be at Target and they only had 2 models - this one and a SONY. I certainly didn't want to buy the RCA given these problems, so I asked the salesperson, who seemed to have some knowlege.

As far as opening the tray on top, there is a button to push right under the tray. The button has an icon of a triangle on it. This seems to be somewhat of a standard icon for opening the tray or ejecting a CD (my car's CD has the same icon for ejecting a CD).

As far as only being able to get 3 CD's out, there is another button under the tray marked "disc skip". This rotates the tray. When you open the tray, you can only get to 3 of the CD's. When you push disk skip, it rotates the tray one position, so you can get the 4th one out. Another push and now you can get the 5th one.

Sometimes my CD changer doesn't shuffle the disks. If I only have 1 CD or DVD in it and push the tray open button, the disk stays in the unit and the tray revolves to an intermediate position. I push the button to put the tray back and try disc skip; that usually works.

If your problems are not solved per above, then I definitely do NOT want to get this.

I have a Pioneer CD player that is probably about twenty-five years old. It has a six CD holder that fits into the changer. This changer moves the CD's in and out of the player. You can play them in order...


It cycles through the CDs because it can not read any of them. The most common cause of this is the lens falling out. These players have the optics upside down. You load the CDs with the label down correct? The lens is probably floating around inside the unit. Sometimes you can reinstall the lens and the unit is OK. Please use a small amount of clear nail polish to "glue" the lens in place. Anything else will cloud up the lens making the unit junk. If that fails to resolve the problem, the unit may need a ribbon cable or just a complete alignment.

Good luck.

Our sony hcd-hpz9 stereo will not allow the 5 disc changer to open. It will play disc 1 only. Any suggestions. It makes a rumbling noise. Is there a way to manually open the disc changer?


this is done by a belt drive. i have seen the belts get old and slip. try to gently pull the door open as you hit eject. If you get it to open and find that it will not fully open or close without assistance this is the problem.

I have a 1999 Lexus LX470 with a Nakamichi audio system with a 6 cd changer in the dash. The cd's will not eject and the screen says error. What can I do about this?


I feel your pain......and did extensive research on the internet.....Google "LX470, CD, err3" or "Nakamichi, CD, err3".

Take a look at this excellent explanation of how to dismantle and remove the head unit and retreive the jammed discs. I have used it and fished out three discs, but the CD Player still shows ERR3. An hour of work, so be prepared.
http://www.celiamania.com/wordpress/?p=135

This is a site that provides repair services once you get the head unit out. http://www.carstereohelp.com/lexus.htm
"Six CD changer, Err message in display, will not play CD's, will not eject or accept CD's. Before repair, disconnect one of the car battery terminals for several minutes. This acts as a reset and may bring the changer back to working conditions. Otherwise, repair rate $385."

The Lexus dealer wants $750 to replace with a refurbished unit. Don't go down that route. Read these nightmare stories.

Don't buy a stray unit off of ebay, it is probably jammed or broken with the ERR3 meesage too!

If the home repair method doesn't work, then it will be better to just upgrade to a new head unit. I am buying a Jensen VM9215HD to get a multimedia system with all the trimmings and full iPod control for $460. Available on ebay or online stores. I'll install the unit myself, but you can get the unit and the job done at a local auto sound store for under $1000.

Good luck,

Onkyo six CD changer stuck closed, reads "Mechanical Error" in window...Also, new Onkyo tape deck TA-RW255 tape stuck, won't open and won't turn off.


The Onkyo CD changer has an internal mechanical problem that could be anything from a disc being jammed in the mech, to a bad belt, or a bad IC or supply voltage that goes to the servo circuit. No way to be certain without troubleshooting it. You can open it up and see if a disc is stuck, but unless you have some experience in this sort of thing it is better left to a professional, You can cause more damage than you started with by trying to fix something you don't know that much about.

The tape deck could have any number of problems as well. A bad belt or gear, a defective servo circuit, and the list could go on, but they are all things that also should be checked by a professional.
Most of the time a tape won't eject is form the tape head being engaged and not letting loose of the tape. But since it won't turn off, you have some more serious problems. That is an indication of something not communicating with the microprocessor. It could be a digital transistor, a shorted capacitor, and like before, many other things. Whatever you do, don't force the tape deck open. It will destroy the head assembly and it may even void your warranty (you did say it was new).
You need to find an authorized Onkyo service center near you. Contact Onkyo if you can not find one yourself.
This really is the best action you could take. Onkyo is a very good brand, and in most cases is worth getting repaired. If it were some type of cheap-o brand it wouldn't matter what you did to it because replacing it would always be cheaper than paying for a repair. That is not the case with your equipment.

If I can be of further help, just ask me.
