Canon 70D Wont Turn ON

My beloved 70D has decided to stop working on me.

Battery is fully charged but won't turn on. The only sign of life is the little memory card light blinking for a couple seconds when I put a card in. Have tried the common fixes (SD card in and out/ poking the switches in the memory card door and battery door as well as taking the lenses on and off).

Would love to hear if anyone has experienced this before!
