In a high-quality schematic PDF, you can often zoom in to see the PCB layout suggestions. This indicates how the manufacturer handled heat dissipation. If the schematic shows a large copper pour (heat sink) connected to a specific pin, ensure your repair replicates this thermal path to prevent immediate failure.
: If you need to trace the circuit manually, high-resolution photos of the board's components and trace paths are available on AliExpress and Blibli , showing the component values and IC markings (like the LYD-3 controller).
