This is a long shot, but I've been impressed with the expertise on this
board....

I have a 10 or so year-old Sony CDP-C70 5 disc CD changer...it worked fine
until I transported it to another location. Now the disc tray won't open
(it normally extends out from the case to load the CD's). I took off the
top and made sure nothing was jammed inside. Further, it won't even play a
disc loaded into the space above the laser. Obviously something got messed
up during transport, but nothing I can see....any clues?

thanks
