Hopefully better late then never, let me describe what is going on here. First, tehse shelf units attempt to get to a know condition everytime they power up. This means that you should here the CD spin and the cassette motors run. I believe that your model (I'd have to look itup to be sure) has either 3 or 5 CD storage inside which means that the whole CD mechanism also attempts to get to a known condition. Should any of these attempts fail, the unit will shutdown to prevent further damage.
The other posters are correct in that Sony does not make service manuals available to the consumer without cost. Authorized service centers pay a subscription every year to gain access to these manuals electronically and are prevented by contract from sending them to anyone.
That being said, the most common fault for these shelf systems in mhy personal experience has been the CD changer/loader that gets out of timing. This requires a rebuild of the mechanism that is relatively simple with the manual and some prior experience. Problems with the output amplifier section can also cause this. The amp problem is easily detected by taking voltage readings during the startup process.
I hope this has helped you to understand the situation better.

Sony is one of those companies that keeps their information tightly wrapped, so the chances of finding a free service manual are quite remote. The answers here are fair, balanced and accurate. The suggestion to take the unit to a Sony service center is consistent with my own experiences, as well.
I hope you find resolution to this issue.

Hi there, the unit may be going into protection mode. This can be caused by many things, but the first thing to check for is dry solder joints
