Gigabyte GA-H61M-USB3-B3 boardview for revision 1.1B, stored as a TVW file inside a zip archive. With a TVW-capable viewer such as Teboview, a technician can search part designators, highlight nets and find measurement points when diagnosing no-power or no-display faults. The 1.1B revision sits close to 1.1, so check the exact marking on the PCB before relying on part placement, as small layout or component changes are possible.
