If your machine appears to have no power at all, then you may wish to try the unit in a different electrical outlet in another part of the house to ensure that the house's electrical breaker did not trip for that particular circuit. You can also test the wall socket with a voltmeter if you have one or you can just use a standard plug in reading lamp to confirm that you have power at the outlet.
If you do not have good power at the outlet, then you may just need to reset the breaker for that circuit at the house's main electrical panel.
Also make sure you try powering on the unit with the power button on the front of the unit itself as well as with the supplied remote. Occasionally there is a master power switch on the unit which has to be turned on first before the power button on the remote will function.
If that is not the problem and the unit will still not power up at all when plugged into a good socket, then the problem is likely in the power supply circuits in the DVD player. If you are lucky it may just be the main fuse inside the DVD player which can normally be replaced after some minor disassembly work with a philips screwdriver.
Before you attempt any kind of disassembly or home repair, you should check with your retailer where you purchased the item about any possibility of a warranty return or exchange. If the warranty is already expired then you have nothing to lose by opening it up and having a look.
Here is a link to a picture of the kind of standard fuse that you might find inside one of these units:

To access the fuse just unplug the unit and remove the screws which hold the casing on. Then just remove the casing and check the power supply circuit board for the fuse. It should be close to the point where the power cable enters the back of the unit. Remove and check the fuse for continuity with a voltmeter and replace with another matching fuse if necessary.
If the problem is not just the fuse, then there may be some more significant damage. If you do not have any significant electronics repair experience and you need to bring it in to a shop to have that kind of work done, then it is unlikely that it can be economically repaired. You may be better off just buying some brand new equipment.
If you do have some electronics repair experience, then you can also check the rest of the circuit boards as well for any obvious signs of electrical scorching, bulging / leaking capacitors, loose cable connectors or other possible component damage.

Thank you very much and good luck.
