This is the new Lasever?!?!?!?!?
Contact David Wu right away! Write down fully what you did, before you forget, take pictures! Treat it like a crime scene!
Try using the modulation built in the power supply to power it up (Assuming you have the lab style, which you probably don't). If you don't - use a known and tested 5v source to test the blanking.
If you have a meter nearby let us know the output of the dim beam.
I wish you the best!
Let us know what happens.
