Hi Roman,
That behavior could be explained by a bad solder joint between the pin and module PCB. If it involves both channels, it could be either pin 5 (ground) or pin 28 (5V). First, inspect the joints with a magnifier, looking for cracks in the solder or separation from the PCB pad. If you see a problem, you can target that connection. Reflow the solder. If the solder has lifted from the pad, you might try adding some liquid flux, which can help solder to adhere to the PCB pad.
