I got this DVD player at a garage sale it’s never been opened but it won’t turn on. It’s a DR430KU
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.
