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.

The system is completely no power.
Today I managed to eject manually tray LD, and not break anything.
But I realized that the "power supply board" is in trouble.
No continuity in 5 IC protector in power supply board and the fuse (125V 2.5A) was burned.
I have replaced the 5 IC protective. I did not find the fuse "125V 2.5A" I used a fuse 250V 2A, but failed. I called but the fuse blew again.
(Note: It confirms the protective IC 5 have not burned.)
The fuse has to be the "125V 2.5A" or can I use any other?
Even as a fuse 225V 2A is normal burn it instantly?
What should I do, please help me.

you can use any 2.5A fuse at or above 125v
that it failed says you likely have something shorted in the supply

I purchased the fuse 250V 2.5A but the two fuses esplodem (2A and 2.5A) before I hit the power button the LaserActive.
They esplodem at the time I plug the power cord into the power grid.
What problem can be doing esplodir fuse?

This image shows the "power supply board"
But now what should I do?
Forgive me, understanding very little of electronics.

updated the FAQ in page 1 with missing -5v issue ( which cause the laser lens bouncing up and down rapidly )
