Red light flashing sudden death

[EUther]

My Xperia Z3 Compact does not turn on. When connected to charger, red light flashing, if halfway plugged in to charger, the interval between the flashes is much longer. I have tried holding down the volume and power buttons to no avail.

You've tried volume up and power button for 10 seconds?

If so leave on charge for a full hour and try the above again.
