Please! How do I disassemble and replace the DVD drive in my PCG-K215B?

[Kei]

Are there any people at all who are experts and absolutely sound familiar with the PCG-K215B?
I've that model, and my DVD writer is 70% dead.
I've been through this descriptions dozens of times...
Cannot read/write DVD+R, DVD-/+RW. Only read some DVD-R. Cannot erase any DVD-/+RW. Can read/write/erase CDs.
I'm very frustrated on this and want to take this stupid Pioneer K12D out and put in a K16.
At first I was certained about the faceplate, but now I don't care, I just want a new DVD writer!

Does anyone know how to disassemble a PCG-K215B (model PCG-9R6M underneath). I've unscrewed all of the screws below, plus the two near the screen/rear connections. It doesn't seem to come off.
Help please, anybody? I've bought 150 blank Maxell DVD-Rs, and my drive can't even read them.

Gish_X, boy, you think it's that simple.
I wish it was, but it's totally a different road, and a rough one it is too.

I can unscrew all of the screws underneath the laptop, but I cannot unscrew the 3 hideen directly underneath the LCD tube, where the screen folds. I'd have to remove the screen and tube then remove the screws and hence the cover.
