"Loading" on SCREEN LCD OF CANON IR 8500

Hi ,
Very thanks for your informations!
I am a electronic techinician in Brasil and repair mother boards and power supplies of many equipments. I received a IR 8500 mother board with bad operation. With this board in Canon machine, display " Loading..." on lcd screen. But do not possible access any function by bars of LCD.
I do not know nothing about this model of Canon, but I will like if exist any reset for this problem, i. e. disconnect battery of motherboard or other proceeding ...I do not view nothing visible bad on this board, but it is possible to have a I/O chip bad. Do you know where I can have a electrical diagram of this board?
Thanks a lot !
