Self Diagnostic

Was wondering if there was any way to have the MPC do a self diagnostic to find out anything wrong with it. My guy tested it out for me before I bought it and he said everything seemed to be in working order, but I just noticed a screw loose/bent and another screw missing in the bottom metal plate of the casing and it looks like the Akai has been opened up before but I'm not sure for what.

I'm not at home but i remember you do this:

- Press "Shift" + "5 (Trim)"
- Press "Shift" + "F1 (Trim)"
- Press "MemChk"

From there you have some options to check/test the memory, pads and data wheel
Hope this helps...

Thanks alot Juke!
