Hi Sincerely
I've moved your post from the V6 forum and merged your other posts into one thread in the TV360 forum.
The V6 box(es) aren't currently affected by a light blue standby light.
Aside from the blue light it's possible that the box update to build version 5.12 has failed.
I see from your other posts that you've reset the hub.
Please try turning off the 360 by the switch on the back of the box; then on the front of the 360 box hold down both the power button and the - (minus) button at the same time. Then turn on the 360 again whilst keeping hold of those buttons for a further 30 seconds.
If the power button and the - button workaround doesn't solve it then try using the power button and the + (plus) button at the same time instead.
