Advertisements Hello I have a Roamio 500 gb, (used only for OTA) in use since May, 2014 with life time subscription. When powering up, the green circle on the left side of front panel and a green led in the center of panel comes on and stays on for almost six seconds and goes out. A blue circle on the right side of the front panel comes on for .5 seconds, goes out, and green circle and green led come on for six seconds, go out, blue led circle for .5 seconds, cycle repeats endlessly until power removed. So can anyone interpret these blinks? Bad power supply, bad hdd, software, MB ad infinitum. I have read on other parts of this forum that if a HDD needs to be replaced in this unit, I can simply install a blank HDD and the box itself will format? the HDD. Is my understanding correct? Thanks in advance for any and all help.
