SOURCE: Why does my ah484 blue
The blue status light flashes because the protection system of the power source - the one that converts the 24 volts coming from the converter on the mains in all the voltages needed by the preamplifier and input controllers (12v, 5v and 3.5v) is active - a part inside the unit has failed - most likely it's related to the KP2 controller since the warning light signals hat is nonoperational. This is a hardware fault, no reset would fix it. BTW there is no reset in this device since there is no processor to be reseted.
The only wy to fix that is to open the unit, test the components, identify and replace the failed one. This is going to be a very complex and delicate job, ask a quote before accepting or you might find out that it would have been cheaper just to buy a new one.
