First off let me explain something.  i have a beocenter 9000 and a beocenter 9500.  The 9000 has a non functioning CD player and the 9500 has a non functioning tape player and non-functioning doors.  I would like to possibly use some parts out of the 9000 to repair the 9500 because i really would like to have another unit with native powerlink connections.

Here is what I have tested thus far:

Removed the 9500's door motors and connected them to the 9000 they work fine.

Removed the 9500's "keyboard" ("buttons" to open doors) and connected it to the 9000 and it functions just fine.

Now I am stumped.  I do want to get the 9500 working... and I do not care what happens to the 9000 hence the parting-out process.  The glass for the 9000 and the frames have already been reclaimed (ie. put away just in case something happens to my other fully functional 9000).  I would like to solve this without the help of Pyramid Audio in Austin or Grammaphone in Denver.
