I think he wants this, not sure
Code:
# All are zero
$ cat <<eod | awk -F, 'BEGIN{s=1}s{f=($1==0 && $2==0)?1:0}f==0{s=0}END{print f}' 
0,0
0,0
0,0
0,0
eod
1

# Not all are zero
$ cat <<eod | awk -F, 'BEGIN{s=1}s{f=($1==0 && $2==0)?1:0}f==0{s=0}END{print f}' 
0,0
0,0
0,0
0,1
eod
0

--edit---

Code:
$ awk -F, 'BEGIN{s=1}s{f=($1==0 && $2==0)?1:0}f==0{s=0}END{exit(f)}'

exit 1 if column6 and column7 are zero in all line, exit 0 if column6 and column7 are not zero in all line

Code:
$ awk 'BEGIN{s=1}s{f=($6==0 && $7==0)?1:0}f==0{s=0}END{exit(f)}'
