Hmm, this was strange. I opened the player to see if I could see anything obviously wrong (which I didn't), when I remembered Tony had some problems with his ac sensor. But I didn't remember what the symtoms were, so I did a search and found this post, which looked to be the same problem as mine. When I connected the sled connector from my spare sled and applied power to check the diode, it powered up properly... even in the sled and after I had re-assembled the player... So now it works again. Maybe the electrons were flowing in the wrong direction or the phase of the moon was a bit wrong or something the other day...?
