You must 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. DVD chassis, you can plug in the unit and check if this helped the player to "see" again. Most of the time you can check as is, though on the combo units you're going to have to slide the chassis assembly all the way back into the cabinet to get it to work because the cables are often too short. If this didn’t fix the problem, please read on.
Other things to check
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.
f 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.
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.
Also, in a DVD/CD player there are many complaints where the disc gets stuck inside of the unit. This could be as described earlier, but there’s also what’s called a drawer/disc tray opener and closer mechanism to contend with. On many models, old and new alike, there’s a small belt that goes bad and wont let the tray open. You can usually put your ear very close to the front of the unit and, if this is happening, hear the motor spinning when you press the eject button. Another cause is the nylon gears, which can get jammed up with dirt and dust. Also, in other cases, you could have a motor problem, or the driver IC could be at fault. If you suspect that the motor is at fault, simply measure the voltage on the tray motor while pressing on the eject button. If the voltage comes up between 6 to 12 volts, depending on the manufacturer, then the motor needs to be replaced.
Alignments
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.

Cna the 1650 av media center control the disc changer in my mitsubishi magna verada or will I have to get a different changer


Not absolutely certain, but they are both main brand items so they share a generic interface, so it should. It will not damage it if you hook it up to try it.

I have a Pioneer LCV-300 Laser Karaoke player; but without the "receiver" or "commander" unit. Is this unit necessary for the disc changer portion to operate or power on?


I may have a CD-V300 commander Auto changer if you can supply me with an owners manual for a LC-V300 laser changer. I also have an auto changer CD-V2000 if you can use it. If you can please contact me. Thanks.

Hi I have a jvc xl m500 6 disc cd changer and the tray won't open help.


I had the same problem. Out of the blue, neither the single tray nor the cassette would eject. On top of that, it wouldn't change discs or even play the disc in the engaged tray. I then unplugged the unit, moved it to my work table, plugged it back it, and it worked fine.
Last year I had a similar problem with the JVC receiver RX750V that I had bought along with the CD player, probably around 1986--it simply would not turn on. I took it out of the cabinet, and shipped it to a JVC repair shop called BC Electronics, Levittown, PA 215 547-7600. They were very knowledgeable and courteous, but said they could find nothing wrong with the unit, and that the unit worked fine. They shipped it back, and the unit worked fine initially. I found that the problem recurred, i.e. that every so often I'd turn the machine on via the on-off switch, and nothing would happen. If I then unplugged the unit, left it off for a while, and plugged it back in, it would work fine. I then installed an in-line on-off switch on the receiver cord. It now seems to work fine consistently.
It seems that after twenty years, this same problem may affect this generation of JVC components, i.e. that the main power source to the unit must occasionally be cut off.
On the other hand I could be completely wrong and just plain lucky...Hope that helps.

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.

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.

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,

Disc changer continues searching for the next disc, but doesn't find one.


The unit is attempting to read the disc and fails. It then goes to the next slot, etc... Try opening up the unit and carefully cleaning the lens with a cotton swab and alcohol. Let us know if that resolves the problem.
