Here are some DIY steps that may help you fixing the problem.
1. Check the power cord - check the cord it might be opened (no continuity).
2. Check the internal fuse - sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I've advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the link http://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.
3.If you see that the fuse is intact on the board, don't attempt to touch anything because there some fatal components stored electricity enough to hurt you with a simple mistake only.
The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is quite technical.
Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.
