My Mark IV is failing to boot up. The Standby/ON LED just flashes off and on no matter how long I wait. Looking underneath, the power supply has four LEDs. Number 2 is permanently lit up, Number 1 flashes on briefly then off for a longer period. LEDs 3 and 4 aren't lit up. Not sure what is normal with these LEDs. I can hear some ticking and scratchy noises from the DIO-100 and the DMC-100 during power on but then goes quiet after a short while. Can anyone offer any advice? Sion
