Hope someone can help me...I've got an MDX CA580 and all has been fine up until 4 weeks ago when it just decided to stop working properly.I can play my MD'S on there but I have to put it in the slot 1st it wont just start up like it used to and when I take the front off it starts back at the beginning again.I cant turn the volume up or down it stays on the one level all the time and the radio doesn't work either (it used to)All the buttons make the clicky noise so they are making contact with the inside.....I also have a little blue box on the display screen now I'm not sure if this has always been there or has just happened since it has stopped working.Hope this makes sense and someone can help.Thanks in advance.Sarah
