I see a couple of similar threads, but not quite close enough.

My problem is that I get the flashing warning light, and no flow on the aux circuit. Once the machine is up to temp and (most of) the warning lights settle down, if I hit the thumb switch, nothing happens in the hydraulics and the warning light flashes. It feels like a sensor is stopping it actuating, though I'm not sure what sensors feed the warning light.
Are there some things I can test before tearing in to the coils or stems?

For what it's worth, I'm 99% sure the aux hydraulics have never been used before, it's an ex rental machine and the mount points for the accessories look undamaged (unlike the rest of it).

I've just splashed out on a new thumb for it, and now I can't use it :(
