can i get my Diamond DVDV807-4 dvd player to work again?

A home made dvd was inserted and the unit failed and does not function at all. (first time usage)

I verified ps voltages, all good at o/p with no load. soon as main brd plugged in all voltages drop, faint green led flashes, no functions whatsoever. all machanical parts seem ok, no jams,
