CPC 1.03 problem

Had an odd problem with my register console this week. The console is still functioning but not working right.... Any ideas or suggestions welcome.

I had just keyed in a set of plates, hung them, and when I returned to the console, no keys or LED's were lit (except the power LED), no matter which button I hit. I turned the console off with the key, waited 10 secs, turned back on. The power LED was on but nothing else would come on no matter which buttons I hit. I rebooted the press and console.

Everything works, but I can't select a unit by the color button (KCMY) instead I could only select a unit by unit number. If nothing is done on the console for aprox 15 min, all the led's on the screen go off, but come back on when you push a button (almost like it has a screen saver!). Also, there is a key (24) that randomly moves it self up alot. At first I thought this was the work of a faulty button, but I noticed that when key 24 randomly moves itself, it moves itself to the exact same spot on all units, hardly the work of a bad button.

The console is working, but if something is going wrong, I'd rather deal with it before it dies completely.

Thanks
