My toshiba dvd model #BDX-2500 Won't turn on when I try to turn it on. But if I disconnect from outlet and then plug it...

Thanks for your input,I decided to pull the cover off, and just behind the power button,there is a circuit board with either 3 transistors or some kind of capacitors that are very close together, which looked like they may have fried, there is some crusty brown stuff that hardened between all 3. Again thank you....
