Audia flight protection mode

Hi I have bought a second hand Audia flight phono stage. It starts in standby and then the blue light flashes fast for 60 seconds, and then it switches on for about 2 seconds. It then locks up with a flashing blue light...so called protective mode. Nothing I do seems to change this. I was just wondering if anyone had experienced this, and if so what the fix was? It seems it worked perfectly in the dealer's demo system, but after transport has this error in 2 different systems. I would really love a quick fix, but the manual and the website have very little info on error conditions.
