Do other things power up OK from your transformer?

If so, then there is a problem inside the MD or with the power 
adaptor.

I think that, unless the MD was in a really well made flight case, 
the journey in the cargo hold will have been quite stressfull for it.

You _may_ need to open up the MD and check that all the chips are in 
their sockets ok, wires in the right place etc.

In Mexico city, there are whole streets in the center that have just 
1 type of shop on them. There is one street with music shops 
(everything from records to PA stuff to a few keyboards). You may 
either want to 

[1] get the screwdriver that opens the MD from one of the 
more 'electrical' type shops, open it up yourseld, and check. You may 
want to buy a multimeter as well.

[2] ASK if anyone can have a look inside for you. This is kind of 
risky, as the MD is rare and new, and I would guess very specialised.

The music street is quite close to the Zocalo, the street is called 
Bolivar. To get there, go to the Centro Historico, and locate the 
Palacio De Bellas Artes in the Alameda Central. Take the street 
called '5 De Mayo' that comes off the east side of the park. I think 
it is the 3rd street on your right. You will have to walk down about 
4 to 6 blocks to get into the music shops. There is also more 
electronic shops around this area, maybe in the street called 'Rep 
Del Salvador' 

I hope you get it fixed in time.
