Can't restore my AppleTV3
I've got an ATV3 and my Itunes is version 12.2.2 (latest). Some days ago, I was not able to turn the ATV3 on and its light was flashing slowly. Following Apple instructions, this seems to mean that the ATV3 need to be restored. I tried to restore it, but ITunes was not finding the device (plugged to my iMAC and to Power). For some reason, after a few tries, I just plugged my ATV3 back to my TV and it suddenly worked... A week after this episode, the same problem happened, but now I cannot solve it anyway! I bought a new USB cable (with data transfer) and ITunes is not even finding my ATV3 as a device. I changed cables and ITunes is still not able to find my ATV3 again. Everytime it is plugged to power and HDMI cable, the light flashes slowly and nothing appears at my TV screen. I Tried also to restart it with the remote (pressing down and menu at the same time for 6 seconds), but the problem persists.
Any Ideas?
