Look for a triple in column 7 to make some eliminations.
Then look for two different x-wings occuring in two different digits to make more eliminations.
You will then be able to fill a cell in block 7.

Please reply if you need a more specific hint.

Update: There are two x-wings present at this point, but only one is needed to fill a cell in block 7.

I had already done the triple, but forgot to recheck x-wings:(

Thanks for the help
