I used my MG7720 and it said it had a firmware update ready. So I did as it said, went into settings and told it to update its firmware. When I looked again it said it had failed it's update and to press the on button to try again. I did that and now all I have is black screen and a blinking power button.

I too have the same problem. I initiated a firmware update as prompted but it failed. The update failed and I clicked the retry option after which the screen went blank with backlight and the power light keeps blinking.

I had the same issue, I unplugged the printer, waited about 30 seconds and then plugged it back in, it then downloaded the update and successfully applied it.

It seems that the program used to cause the download / update is incorrectly programmed, and is failing at some point?
nice to see the old turn it off turn it back on works.
i wonder how many people have actually had this problem and how many engineerrs / new printers have been dispatched at an incredible cost in time to both users and Canon.

I had this problem as well. I tried power cycling the unit twice and it still failed each time. However, for all 3 attempts the printer was connected to the network over WiFi. I turned it off, plugged it into the network with an ethernet cable, powered it on and then it worked "first" try.
