Power cable hooked positive to negative, now does not power up

Power cable hooked positive to negative, now does not power up I made an adapter power cable, but I wired it backwards positive to negative. Now with a correct wired power cable the green light lights, but the unit will not power up when pushing the on/off switch. What component is most likely damaged and can I replace the damaged part?

Try just holding the power button for 15 seconds. This is supposed to reset it. I can't find a schematic, so I can't pinpoint the most likely cause, but look for something burnt if holding the power button doesn't work.
