and it turns off when I run another procedure like sounds.

Does the other procedure use the same serial bus as is used to the TM1637? Is it possible that the sounds procedure uses some of the same serial bus pins, which might look like a shutdown / display-off / reset / clear etc command to the TM1637?

Does the 4 digit display shut down **before** you use the sounds procedure, or **when** you use the sounds procedure?
