Controller's board is flashing yellow 3 times when connected to power

I didn't fully put it back together, just plugged the battery in the board and then connected it to my laptop via usb c to check the calibration tool. It is not showing up on my pc, it did show up prior to changing the analog modules.

There's your problem!

• The battery provides power, so the microcontroller wakes up.

• It quickly performs a self-check.

• When it sees missing connections (like the USB board, touchpad ribbon, or trigger lines), it flashes yellow 3 times and shuts down to protect itself.

Go ahead and put it fully back together and then test it.

Get back to me if it works

@carsons45505 Thank you! This didn't work for me, in the end I desoldered it and soldered everything again. Now it works like a charm, appreciate your help!

Well, I got same issue for no reason suddenly it start flashing 3 times every time i press the power, plug the usb or even charging using the dock … after flashing nothing happened. I tried another battery but problem persist… I tried to disassemble everything… no ribbon cable is connected… only the board ( with analog sticks) and the 4 wires for the vibration motor but no success … reconnecting all ribbons ( trigger and touch pad) again but no success … any suggestion please!

Update!! .. I found 2 defected capacitors close to the power IC that causes the problem 😩
