Pioneer DVD-120 Strange Ejecting Problem

Hello all

I have a weird problem. My pioneer dvd drivers tray is unable to eject , but only when there is no disk inside. In order to eject it, I press eject button 6-7 times, then eject out. If there is a cd/dvd inside , everything is normal. Btw, there is no cd/dvd reading problem. Do u have any idea about the strange problem? Thanks.

Any idea? :rolleyes:
