If a resistor or capacitor burns up, its markings disappear. A boardview will tell you exactly what component belongs in that blank spot (e.g., C512 or R203 ), allowing you to cross-reference it with the schematic to find its exact value. 3. Repairing Broken Traces

Displays the exact location of resistors, capacitors, diodes, ICs (Integrated Circuits), and transistors.
As mentioned earlier, this is a firmware issue. The Boardview is essential here to locate the BIOS chip (usually an 8-pin SOIC chip like Winbond or MXIC). Using the Boardview, locate the physical BIOS chip on the motherboard. Desolder it or use a clip to connect an external programmer (like CH341A) to reflash a known working BIOS dump for the 4520s.
