thanks for the guide buddy, my xbox wouldnt play anything(games or dvds) but i used this guide to strip the bugger down, and found that it was dustier than an old ladys privates, cleaned the laser and and the cpu, now it works a treat. so if anyone has the open tray error then the best bet is to use this guide, strip it down step by step and clean the bugger but be careful not to damage any components and do not " I REPEAT DO NOT TOUCH THE LASERS EYE WITH ANYTHING OTHER THAN A SOFT CLOTH. Best to use the little green one that comes with LCD tvs if not then a little cotton bud will suffice. Thanks Again for the guide bro, saved my xbox..
