Hardware technicians and circuit board engineers regularly search for schematic files to trace faulty voltage rails, repair blown HDMI or VGA video outputs, or recover systems that suffer from the notorious "stuck on boot loop" hardware failures.
Because security cameras are often mounted outdoors, lightning strikes or ground loops can send high-voltage spikes down the coaxial cable. This routinely destroys the ESD protection diodes or the main decoder chip closest to the BNC ports. Troubleshooting Map: How to Use the Schematic ds80249 p rev 12 schematic link
