My colleague faced the problemthe tray had no opened when he pushed the eject button.He asked a help and I offered a big help without knowledge how many screw has to be remove :)Gear wheel issue is a type error of the phillips 950 CD player as I learned.Finally I solved the issue because of I designed a gear wheel (not the same I modified a little for strong)You can watch on my YouTube the wholestory with pictures in 4minutes.

If you like my design or/and video please support me with tip or buy my model, so I can design and print more parts.Thank You!
