Perhaps something like this.

[/tmp]$ cat try.ksh
#! /bin/ksh


echo $str | tr ',' '\n' | while IFS=: read hour min
    if [[ $hour = *[:alpha:]* ]] ; then
        echo "$hour:$min is invalid"
    elif [[ $hour -lt 0 || $hour -gt 23 || $min -lt 0 || $min -gt 60 ]] ; then
        echo "$hour:$min is wrong"
        echo $hour:$min
[/tmp]$ ./try.ksh
a:23 is invalid
25:67 is wrong
