There is probably a loading belt that has become stretched and the tray is not completing the cycle, " meaning it is not opening all the way and ends up closing just as fast " this a tricky repair best suited for a professional.

Tray won't stay open

My unit closed immediately upon opening since like 1 day after the warranty ran out. It bothered me. I finally tore it apart and this fixed it.

Take the cover off. As you are facing the front of the player, the blue sensor switch that controls the tray will be on your left in the middle of the carousel. Push button to open tray and locate it as the tray opens. Grab the tray and also the carousel and hold them so you can see the little blue switch. Use a tiny screwdriver or toothpick or other slender device to "flick" the switch fully forward and backward several times. Let go of the tray and try the button. If it still closes immediately, repeat the flicking. Try it again.

Pioneer Dv 285 powers down after 15sec

Hi There, I've got the same problems with my DV 285. My power started going off approximately 5 to 10 minutes into the DVD. The only button that seems to work is the OPEN/CLOSE button. Once the tray closes, the unit shuts off. I can't even use the on/standby button to turn it on.
