Pioneer CLD-D505 Question

I've got a Pioneer CLD-D505 that does not power on and I need to check the fuse and power supply outputs.

Only problem is I can't get the tray to move out of the front of the unit to gain access to the power supply board. I've spun the motor on the left side of the unit but this only advances the CD tray, not the big LD tray. I've looked for some sort of an "eject" function but can't find anything. As I see it the two spur gears just behind the front panel need to release to get the tray to move out. It can't be lifted because the front metal bracket. I hesitate to pull the front panel off since there are connectors underneath.

Any clues?

Thanks
