Hi guys.
I had the exact same issue. I found out if you unplug the power cord for roughly 5 minutes and give it a good tap on its base it turns right back. Step by step I did the following; unplug and let sit for 5, tilt the console on all 6 angles for a few seconds each, tap the Base of the console a few times (not hard though) now when you power up it should work. I was petrified when mine knackered up too! Glad this worked for me, hope it helps you!
