The system is completely no power and just the ld tray is not out? If it still have power, out probably wait for the system turn on for 30 seconds, so the tray is completely unload, then try to turn the gear. If still only the cd tray comes out but not ld tray, I bet the tray or loading mechanism is broken or misalignment .
I used to have this problem (loading mechanism or tray is broken and only cd tray comes out when turning the gear ),the only way I can do is force it to come out but it will break the tray or load mechanism for sure!!! The reason I did this is I have complete tray/load mechanism replacement from eg, cld-s260. Thus, I force the tray come out and replace both loading mechanism and tray.
If you don't have replacement, don't force the tray to come out, I am so sure it will break it. Try to play around with the gear and sometimes , the ld tray may come out in certain position I guess. However, I am pretty sure either your tray or loading mechanism is broken or misalignment during the drop, otherwise, the ld tray should come out when you turning the gear.
