Phillips DVD player whistle

Saw a DVD player for sale this week in Gum tree And went and bought it. £20 Phillips Seemed ok when he showed me in his flat…

Then when i got it home Still seemed fine. Then To my horror when there is no media in the drive There’s a constant hydrodyne whistle Till media loaded.

What is the cause please?

solved it myself

Use remote: 7-8-9-OK-0 with the draw open whistle is has gone why… i wonder …
