So, did you figure anything out yet? Or have a hard time admitting I was right?

You really don't understand what you are doing do you??
Do you think Philips have some one sat teaking pots and checking resistance values. This has nothing to do with resistance values at all. The procedure would be similar for all laser adjustments regardless of the type. You need to use the scope to obtain an "eye "pattern on the relevant test point and adjust this for maximum amplitude. Go too far and the signal will be clipped and the machine will read nothing.
One of the pots you refer to is  to set the noise threshold.
Now here are the facts I have spoken to the Philips TLO and no service information is available third party for the drives for the Xbox to dealers or third party service agents other than specifically appointed M$ service departments.
The drive will probably be very similar to other Philips model drives but the problem is the location of the test point for the output will not be the same.
So to repeat we were never talking about getting you resistance values for the Pots becaus ethey are not set like that at all. I was hoping to obtain you the test refernce data including points for measurement Frequency and Amplitude figures so you could set the drive up correctly, if you have not already damaged it with the tweaking.
One other thing if you are so right how come your drive ain't working?
If you want data for a similar drive you will have to email me as the manuals are around 7mb each so would have to be sent by attachment.

sorry dbl

You are right.. I had been waiting for a response from you, and didn't get any.. so I figured I'd get one if I'd challenge you a little and possibly piss you off, I might get a response. And it worked ;-)

Your information is useful, though I'm not sure what you mean with an eye pattern, except perhaps setting the scope to half the frequency of the measured signal so the sine wave is half off, overlapping, creating the eye shape.

P.S. I am not planning to go blind doing this, but how about looking at the shape/size of the laser light on the disc? A writable disk is somewhat transparent.. I am sure the laser light is very very small. Perhaps too small to usefully be able to measure. But I'm guessing if it were possible to 'see' (with a camera, if it doesn't get damaged, zommed in maximum) the laser beam onto the disk, to maximize its intensity and minimize its size on the disc. Go ahead, laugh.
