Hello.
As you can see the attached files, two pins on LEDs are shorted to ground. It is PCB Soldering problem happened. It seems to destroy or fool the circuit.
While charging, Only Red LED lights on(this is expected result) and I did not want any current flow across R1 into ground(Blue line). Voltage drop across the LED is shown to 5V because it is shorted to GND.
When charged, Only greed LED is supposed to be on, not Red LED.
Even charged over 10 hours, only RED LED stays on. Green LED is never turned on(this is the problem to solve....).
Could you analyze this problem and share your idea?
V1 : Power from the USB
V2 : Voltage at STAT pin from charge controller based on the states.
