The quickest way to do this if your comfortable with opening electyron componants is to take the top of the unit off. there will be a cover over the disk carousel that has to be removed as well you will be able to remove the disks from there and then replace everything back in the same order. becareful not to wear clothing that will hold a static charge, a discharge on the circuit boards will fry them. also do not touch the optic glass of the laser this will damage it. please rate the solution...thanks

First you do is to reset the unit,just unplug the unit for 3 - 4 hours and re plug again.If nothing happens then that is the time you open the receivers.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. Hope this may help; Regards, VOTIT

I own a technics CD changer Model SL-PD 787. The system powers up showing the disc & track no. but the timer does not count down . and therefore does not play. How can I fix the problem.


Actually it's the other way around. Playback makes the counter move. Did you hit PLAY or try to seek to a track or anything to verify it 'likes' the disc?

CD jammed inside player


Remover the player's cover. That will give you access to the player's internals and therefore also the CDs. That is the only way to go about a problem like the one you are facing.

Disconnect the player from the mains supply before doing this.

Good luck.

My Technics SL-DV290 stereo has stopped playing dvd/cds, it just says 'no read' when it initially scans dvd/cd prior to play Please help!


This means that the unit can tell that a disc is present, but can not read it. Try opening up the top and cleaning the lens using a cotton swab and alcohol. Let us know if that resolves the problem.
Thanks,
Dan
