Because the Oppo A15 uses an IPS LCD screen, it requires a high-voltage backlight driver circuit to illuminate the display panel. The schematic maps out the step-up coil, diode, and driver IC that generate the roughly 16V to 25V required for the backlight. Network & RF (Radio Frequency) Section

If you can’t locate the schematic, consider using on a donor board to map common components (charging coil, test points near the power button, etc.) — this is often faster than hunting for a rare PDF.

Let’s break down what you will actually see in a legitimate PDF file. Because the Oppo A15 uses an IPS LCD

If your phone isn’t charging, check the voltage at the charging port. Using the schematic, locate the VBUS and GND lines. If voltage is present, the issue may be with the charging IC or the battery itself. iFixit guides suggest that replacing the charging board and flex cable often resolves these problems.

The charging path starts at the sub-board (charging port), travels through a main flex cable, and enters the mainboard through a BTB (Board-to-Board) connector. It passes through an Overvoltage Protection (OVP) IC before reaching the secondary charging PMIC. Display & Backlight Circuit
