There are a couple things we have seen cause this. We see a lot of the times a few capacitors in the power supply fail and cause it to shut down. However we have also see the logic board and main board cause this. Do you know how to use a meter? If so I can help you troubleshoot/repair this. If not, you will need a engineer at this point, the bad news is repair generally runs around $300-400.
