sc547 is a power supply error that can mean you have a faulty power supply. The service manual does not list an sc689, and it's not in the help desk support database either... are you sure that's the code that comes on the screen?

It is a cooling fan that has died.....I copied the following directly from the service manual. It's been a while since I've seen one of these machines, but the fan is either inside the rear panel, or accessible through either side (wherever there are vents in the panels basically). If you're at all technically inclined you can usually tell which fan it is by simply spinning it, and if it's not free, it is trouble...fairly standard fans, as long as you get the proper direction of airflow, and similar amps.
