Hello,
I have an MX-850 that will no longer upload or download the programming data without errors. The programming in the MX-850 got corrupted when I tried downloading and received Fail and other error codes. I tested the cable and com setup by uploading and downloading from another MX-850 and an MX-700, and they work properly with no errors.
I tired the procedures in
this thread for clearing the ram, running test mode and uploading a new 10 item setup, but the errors continue. It seems that there must be a faulty jack or PCB.
My question is, will an MX-700 PCB work with an MX-850 shell and buttons? I prefer the feel of the MX-850 buttons and the select button to the MX-700. They look the same but I do not know if the swap will match up OK.
Thanks for any help.
