My KM-2050 won't go past the KM logo. I'm told that re-loading the firmware will fix it. Does anyone know where I can find the firmware?
Check to see if one of the keys on your op panel is stuck down. Press them all one at a time and make sure they each have a good click. A grain of crap can get stuck between the key and the op panel frame and cause the key to stick down. I have seen this cause the same symptom you are getting. If that's not the issue you should follow Leroyal's advice from the first reply.
