These DVDs will not give info on service menu because the parameters vary from brand to brand and model to model.
You should be able to calibrate your picture in the custom picture mode using the regular menu. I sincerely doubt you would need to adjust in the service menu.
If you decide to anyway, get the manual, and in Video Adjust 1 look for sub brightness, sub color, sub contrast. If you need to adjust geometry those are in the deflection section of the service menu. Again, the manual would help you.
Also check the thread in hometheaterforum.com under Samsung TXL2791F which is the model I have.
