I can give more specific troubleshooting steps if you have the unit open.

Wlx-896b Schematic – [Clarity/Accuracy/Completeness] Assessment

Fireproof, high-temperature resistant ABS+PC plastic 2. Block Diagram: The Four Stages of the WLX-896B

: High-voltage electrolytic capacitors (typically rated at 400V, 47µF to 68µF) smooth out the rectified waveform into a stable ~310V DC bus (assuming a 220V AC input). 2. Flyback Switch-Mode Power Supply (SMPS) Stage This stage handles voltage step-down and safety isolation. Wlx-896b Schematic

If you are using this information for repair, focus on these high-failure points: Likely Culprit Blown Fuse or Primary MOSFET Check input fuse and power transistor for shorts. Flickering / Cycling Dried-out Electrolytic Caps Look for bulging capacitors on the secondary side. One Port Not Working Physical USB Port Damage Inspect the internal pins of the USB-A female socket. Low Voltage Output Feedback Loop Failure Test the TL431 and Optocoupler . ⚠️ Safety Warning

Real-time independent voltage (V) and current (A) reading per port

Burned, Cracked, or Out-of-Tolerance Current Sensing Shunt Resistors I can give more specific troubleshooting steps if

in the primary stage, which are frequent failure points during power surges. (like a dead display or no power) or to modify the output

Check ESR (Equivalent Series Resistance) on the low-voltage electrolytic capacitors filtering the 5V rail. (Other ports work flawlessly)

: This chip drives a high-voltage MOSFET to pulse the primary winding of the flyback transformer at high frequencies (typically 65kHz–100kHz). Flickering / Cycling Dried-out Electrolytic Caps Look for

The WLX-896B is likely built around a . This is the industry standard for offline power supplies below ~100W because of its simplicity and low component count. The schematic can be broken down into several functional blocks.

A specific port charges a phone successfully, but the LCD reads 0.00A or stuck at an erratic high value.

Integrated Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP).

A central microcontroller (MCU) scans the small voltage drops across those shunt resistors using its internal Analog-to-Digital Converters (ADCs). The MCU calculates the active amperage and outputs the values sequentially to the segment LCD display panel. Core Specifications Table
