In this video, I go over a very common issue with the Mid-2010 15" and 17" MacBook Pros with the nVidia GeForce GT 330M dedicated video card. Essentially, what happens to these systems is a capacitor on the GPU framebuffer power rail fails, and starts to pull the rail low. When this happens, it will cause the machine to kernel panic when switching to or running off the dedicated video card, and in some cases can simply cause no image to appear on the LCD at all. In this video, I go over the process of replacing this faulty, undersized capacitor with one of the same specifications that is much larger, preventing this issue from ever happening again in the future.
