The hard drive has probably failed. In spite of it rotating, the head servo and electronics has to work. I would recommend testing the drive in a computer to see if it works. You will likely have to reformat it after if it does work. FIRST look for obvious things in the D888 like cable that is partially off or loose.
The unit may have the problem that befalls the Palm Pilots where something gets under the escutcheon and presses on the touch screen at the edge which overrides any other inputs.
Another possibility is a stuck button. The buttons are usually scanned as a matrix and at startup if a button is stuck that can make unit unresponsive.
Without a logic analyzer and the firmware listing you likely would not get far if one of the logic chips has gone bad unless it can be found using freeze mist and heat gun..
Stuck buttons or touch screen is usually easily found without schematic.
The effects on the PMP powered mixers flash UNTIL you push in on the selector knob. This way you can dial in the next effect number and then push in later to activate when you want it... Could yours possibly be the same technique?
