How To Open Sony VRD-VC10 Drive

Hi to all,

I am stuck up with opening my sony external vrd-vc10 dvd burner. I have problem reading and writing dvds. I am able to read cdrs though. I read somewhere on the net that i need to open the drive and clean the lens. But after removing all the screws i am still not able to open the body of the drive.

If anyone knows the steps, i will be glad.

Thanks.
