If it is in a garage i don’t think will turn on. Maybe someone thrown it because it’s faulty. Still you can check some below points:
* Open cover of your Toshiba DVD player.
* Clean dust and check carefully any spark mark or cuts. If there is a spark mark like a short circuit(black mark), it won’t turn on. You have to replace that burned parts.
* Check cable wire with ammeter may be its damage.
* Check power supply unit of the DVD player.
