1991 Mercedes 350SDL Instrument Cluster Failure

Hi all. The gauges on my friend's Mercedes 350SDL just failed. All of the gauges except the Clock completely failed simultaneously when she was driving it. The speedometer went to 0/ all other gauges went to zero. I'm assuming that it needs a new instrument cluster (similar problem on my 735i). However, is it possibly a bad fuse? I'm short on details from her, but she wants to take it to a mechanic and get it fixed; It will cost her a heavy chunk of change. Secondly, her speakers seem to work intermittently, usually when she goes over a bump. Any suggestions? Thanks guys, I'm new to the forum.
