    I have the same problem whenever i insert a CD it spits it straight out!!!

    i have found the disc wont even start spinning to read any data i have opened the unit up and kept trying to get it to read then it started spinning after about 20 minutes on trying to load a disc.. it seems very random but once it works the first time it will continue to work for a while..

    i believe the laser might need to be cleaned or the motor is on its way out..

    if anyone has any way to solve this issue please post here and email me

    Hi, I have exactly the same problem, except I have the CDJ-400 CD Player. It seems that after 10 or 15 minutes it seems to finally recognise the disc, but the problem is getting worse. Any ideas appreciated.

    ebay between 20-40 bucks (random info) if it jumps back 2 seconds or so when playing it could be the stepper motor (the motor that moves then laser assembly along the track)

99% laser module is faulty.
if u try to push your cd and it returning it or your cd stuck inside and it stating no disk, find a new laser and replace it.

If you had it apart check the white disk on top it should be flat not on an angle and while your there add a little bit of carbon to the top of it (so it spins freely) if it has to much friction it will cause the cd to slow which will make it skip (no it wont slow the song down LOL)

Half an hour ago the player was still working fine. Now it's impossible to eject cd's and the player itself gets confused cause the cue goes on and off by itself and playback skips. HELP

The CD drive in your CDJ is hunting for the disc, i.e it has become difficult for the player to read the disc. Keep your ears next to the loading slot after inserting a CD, you will hear a motor spin up then slow down then spin up again and if this continues the system will lock out the eject function. Or else the disc will come flying out!!. Either you need lens cleaning ( try a cleaning kit ) or replacement ( If the player has crossed over 500 hours of use )
