whats wrong with my ps2? video!

when i press eject, it comes out like a centimeter, then makes a whole bunch of racket. to open it up i have to force it open and once it opens, it closes by itself!!

that happen to me once before.  Where I would press eject, and it would open the tray, then slide in by itself.  It happen to me for a day or two before it start to work normally again where it doesn\'t close the tray by itself when i eject it again.

i have it stand vertically, and try using the console again for a few days and see if it still happens.
