DVD players are compact complex pieces of circuitry. They're easy enough to manufacturer on an assembly line, but there are so many little components that could break like diodes, chips, or a burned out resistor so unless you have the tools to trouble shoot that level of component there may not be a lot you can do.
Sounds like you have a voltmeter anyway I'm assuming you used to check for power coming into the unit, and you opened it up to check fuses.
Can you see if there is anything coming out of the transformer inside the unit? They don't usually go bad but some component between the transformer and the board could go bad.
As I eluded to above...once you get past the transformer, now you're talking about troubleshooting at the component level which with the tools you have you may not be able to do.
So I would as far the input power which you did, then what's coming out of the transformer. If you see nothing coming out of the transformer then the problem is somewhere between the transformer and input voltage.
If there is something coming out of the transformer probably in the 5V range or lower, then you'll have to trouble shoot components and circuits. At that point you either take it to a repair shop that has the tools (oscilloscopes, circuit testers) to trouble shoot that level of component. OR just go out and buy a new one. The prices on these things has really come down so you may pay more to have the thing repaired.
