Boardview in TVW format for a Z370XP SLI desktop motherboard, revision 1.0, named after the Intel Z370 chipset. TVW is the Teboview format and typically requires Tebo-ICT View or a compatible viewer to open. A technician uses it to locate components, follow nets between parts and find test points while hunting shorts on VCORE or memory rails. No brand is stated in the name, so confirm the board model and revision 1.0 printed on the PCB before working from it.
