Never solder or probe components with the battery or a USB charging cable connected, unless you are performing active voltage testing.
Make sure you have your Oppo A15 User Guide handy for basic specs before you start soldering! What’s your next repair project?
Use a multimeter in diode mode. Check pin 3 (VBUS). You should read 0.4V-0.6V drop to ground. If you read 0.000V (short), there is a shorted capacitor on that line.
The OPPO A15 schematic diagram PDF is essential for various reasons:
: Positioning of the 13MP triple camera setup, 4230mAh battery connector, and the fingerprint sensor. oppo a15 schematic diagram pdf top
This flow chart shows the logical order of voltage lines: VBAT -> VPH_PWR -> PWRON -> VREG_S1 -> VREG_S2 -> RESET -> CLK If you lose voltage at step 3, you know the power button is faulty, not the CPU.
The OPPO A15 uses an eMMC chip that combines storage and memory controller. The schematic shows the , CMD (Command) , and DAT0-DAT7 lines. A break in the DAT0 line will cause the phone to stay in "EDL" (Emergency Download) mode.
