2000 Gs300 Cd Changer Jam

[Breakaway]

My cd changer in my 2000 lexus GS 300 (platinum series if that matters) is jammed in my changer, it wont eject. However it will still play the cd's that are in the cart.. It will not play disc 5 or 6 (which is the cd that i think is jammed) but it will play the other 3 cd's that are in there (1,2,3). Is this a fixable problem or is this something i should take to the dealer to get fixed and looked at by a professional?

Any tips on things i could try before i start to mess with things?
