If VGH (gate high voltage, ~25V) is missing, the LCD will show a white or gray screen. Without a Boardview, you'd probe blindly. With it, you:

Here is why the Boardview is essential for this specific board:

The boardview had pinpointed the location. Component U49 . It was a tiny chip, barely 3mm square. The thermal camera hadn't caught it because the heat was dissipating across a large copper pad underneath, but the data didn't lie. The gate of the MOSFET was internally damaged, pulling the entire system down.

To effectively use a Boardview file, you must understand the physical zones of the . If VGH (gate high voltage, ~25V) is missing,

He looked at the ammeter. The current draw jumped from 0.00 to 0.15, then to 0.45, then spiraled up to 1.2 amps. The characteristic "heartbeat" of a booting CPU.

He checked the voltage. It was low. Too low. 0.2 volts instead of 3.3.
