Does anyone have a repair/replace diagram or procedure for the Menu button? I have a replacement button on order from Pioneer but I cannot find a procedure to replace it or any of the buttons on the front of the unit. The hardware manual does not discuss repair/replacement procedure.

Thanks!

Try the service manual found here:

The service menu has a lot of expploded parts and diagrams, along with various logic diagrams.  But aside from software related testing and configurations, there is no remove and replace procedures.  Thanks for the link though.  If anyone out there has removed the pieces to replace the menu or other buttons, I can take an informal procedure, I just want an idea before I crack this thing open......

Disassembly starts on Service Manual page 224 (page 231 of the PDF).  Once you remove the "Monitor Unit" on page 226, you will have access to the buttons.  Good luck.

I missed it or was too impatient to wait for the pdf to load.  Thanks!!!  I'll give it a try

Worked great, Thanks!
