The screens in both by chrome and stainless steel VAMOs are solid. It sounds like your VAMO was not assembled correctly which could also mean that the board isn't where is ought to be. You should contact your vendor to return it.
I have seen precious few people indicating that they have been able to get the press fitting off the top of their VAMO without damaging it and, sometimes, not even then. However, this video shows how to get your VAMO apart and put it back together again if you want to try to fix it yourself.
