The Yamaha AN1x Synthesizer mailing list

I tried updating the OS of my AN200 by following these instructions:

http://www.yamaha.com/yamahavgn/CDA/KnowledgeBase/KnowledgeBaseDetail/0,,CNTID%
253D22646,00.html?TextKeyword=an200&selectAreas=400445

I got to the point where the display says 'Fb0C'.

I turned it off and then proceeded to go to the next step, but it won't turn back on!!!

The display is blank, no sound, no anything.  I tried sending the update again, but that didn't 
do anything.

HELP!!!
