My iPad mini retina is out of warranty,
I forgot to plug in my iPad after the critical battery warning and it went some minutes following the warning. I was not worried because same thing had happened a few times before and iPad was perfectly okay after charging it. However, this time I remember seeing a flash of blue screen immediately after it went black. Then, I plugged it in an waited for a while and tried starting it. Ever since, it fails to start hanging on the apple logo with white background screen.
I tried to connect to my Mac but nothing showed up in iTunes. I am worried now. Can I troubleshoot this or is it broken and needing repair?

Assuming it is now charged…
Hold Home & Power buttons for at least 45 seconds, see if it starts up normally.
If not…
Keep holding the Home button until you see a screen telling you to connect to iTunes.
If the above doesn't work, you may need to get a fully operational iPad charger and plug it into the wall. The current and voltage needed to wake an iPad with a deeply discharged battery (or one that's malfunctioning due to age) is higher than a computer can provide over USB.
At that point, you can let it charge for another hour and try again or start with a different cable or a different charger. Eventually, you'll need to have the iPad serviced if it cannot wake from sleep due to a very low batter charge condition even when plugged into power.
