I have also had this problem from day 1 with my Empeg. I have had it in my car for 8 months now and about 75% of the time the Empeg will boot up and immediately go to standby when powered on. This happens when in player mode, when the Empeg is in Aux mode it comes on most every time. I don't think it has ever failed to come on when in Aux mode, just intermittent when in player mode. My wiring is fine, and the player has had flawless operation when running. I am at some point going to try putting diodes on the power wires for isolation. Has anyone else ever had this problem?
I am running V2.0 and Hijack V3.80
