This document provides schematic diagrams and parts lists for several Sony digital video camera models. It contains 12 pages of schematic diagrams for the VC-416 printed wiring boards, descriptions of parts, safety warnings about critical components, and a table of contents. Safety components are identified by mark 0 and must only be replaced with the specified part.

SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
1. Check the area of your repair for unsoldered or poorly-soldered Unleaded solder
