I recently bought a Teensy 4.1 with soldered pins through PJRC and when it was first plugged in, it didn't have any kind of response. The LED did not turn on and the windows device it was plugged into, did not recognize it. Later on it was plugged into a Mac and the LED turned on but just faintly and with a constant brightness, no blinking but when the micro usb cable was moved or twisted the LED increased its brightness or was lowered. The programming button does not seem to respond at all. But when measuring the power throughout the Teensy with a multimeter, there is power flowing though it and the ports for 5V and 3V (3.3V) had precise readings. Another Teensy with the soldered pins was also tested and plugged into a windows device and it was working properly. Any help would be greatly appreciated.
