Two brothers, Amit and his brother, disassemble a projector to show its internal components and explain how it works. They start by removing the screws and taking out the circuit board, and then proceed to show the various parts, including the screen, LED light, cooling unit, lens, and reflectors. They explain how the projector produces light, reflects it, and displays images on a screen. The brothers also show how the projector's focus can be adjusted using a ring and how the image can be straightened. Throughout the video, they provide a detailed and scientific explanation of how the projector works, and encourage viewers to like and subscribe for more informative videos.
