Does the unit play in vinyl mode if you turn the platter by hand?. If this the case the commom fault in the "sheet switch" which is under the platter and sensors the pressure when you press the platter.

The "sheet switch" and it is a circular plastic "sandwich" of multiple contacts and when constant pressure is put on it (i.e something is sat on it for a long time), it tends to stick together giving the effect you are pressing it when you're not.
The part will cost you about £30.00 + fitting - unless you are confident enough to do it yourself

Sometimes so CD does not play in certain CDJ, i have 2 or 3 disc which
does not play or eject when i try to play in CDJ 100s but when i play them
in another player they go well.

Pls try to have some other brand disc or you may clean compartment of the CDJ their may be dirt inside CDJ. I hope this will help.

thx,

djajay

hi there,
you need to clean compartment of the CDJ, there must be dirt which dont let the cd play, also let me know it you get any error code.

Have you tried cleaning the lens out? Invest in a good quality CD cleaner. IF this does not solve your problem, then you more than likely have damage to the reader, and will need to be replaced.

Contatc Pionner for nearest authorized service center - they will either help you or be an a--hole

Are you getting error messages? Running in thru LINE? Is not on mute? The possiblity of both not playing would lead to process of elimination.

Keep me posted.
