try to perform a hard reset by turning off Chromebook completely and press power for about 30 or 60 seconds to drain any residual power,then reconnect the ac adapter or power and try turning it on. I am wondering when you say the display is blinking what is it saying on the screen or it is blank and could you try to boot recovery mode esc+refresh+power if that works than maybe you could recover it. and I am wondering what happened if you know before it started blinking.
