sed command to replace a line

There is a file sample.txt. The contents of this file is

..some content...
  # bind-address = ":7086"
  # bind-address = ":8086"

I want to uncomment the line for port 7086 and replace the port also to 8888 so that final modified file would look like

..some content...
   bind-address = ":8088"
  # bind-address = ":8086"

I want to do it with the sed command. So what will be the exact command?

As confirmed in comments, the string always contains # bind-address = ":7086". So to replace it just use sed search and replace option by hardcoding the strings.

sed -i 's/# bind-address = ":7086"/bind-address = ":8088"/' file2
