Is it possible that all of my FETs are blown?

First off, new here, my first post.
I'm starting to try to repair car audio amps, this is only my 3rd amp, and i'm stumpped.
American graffitti S/X-2.10 amplifier.
when hooked to power source, goes instantly into protect mode. no hesitation, no power light at all, just protect light.
Testing the FETs with this method,

1/2 way down the page.
with the first test, i get the same exact reading on all 8 FETs, which is about 850 from the gate to drain, and 400 from gate to source.
is it possible that all of these transistors are blown?
