The "teardown" gives you a general overview of the product. In other words, you get to see the forest before examining the trees. Without it you would just have repair guides on individual aspects of the unit and not a complete picture. What this unit needs now is for someone to create specific repair guides for parts and trouble shooting. Your input would be welcome. Just click on the "Contribute" icon in the menu bar and it will guide you to how this can be done. You too can help others.
