My disc tray is really screwed up or the laser Idk which or both. I need to get a new one, but the problem is I don't know what kind of brand I need to get Benq, Liteon, Hatachi, samsung there is a bunch of these and Idk which one is mine and don't know which one to buy off ebay. I looked at some pictures of disk trays and mine seems to look like a benq. but is there a better way to check. Also does anyone know if I have to buy a whole new disk tray or just the laser?
