I have an EOS 70D, about four years old. After a three month

Customer Question

Hi, I have an EOS 70D, about four years old. After a three month gap when I didn't use it, I now cannot power it up at all. I have a fully recharged battery, but when I switch the camera on there is no flicker of power. I have checked there is a memory card and that the battery cover and memory card cover are closed. Any ideas?
JA: Are there any flashing lights, symbols, or messages on your camera or display screen?
Customer: None at all. It is completely dead.
JA: Have you tried removing and replacing the battery and/or SD card?
Customer: Yes I have.
JA: Anything else you want the Camera Expert to know before I connect you?
Customer: No, I don't think so. Thanks

There are two micro-switches that will prevent the camera from powering up;

One is on the battery door. The other is on the memory card door.

There are some tiny tabs that engage the micro-switches when the doors are fully closed.

Can you check to make sure the doors (and tabs) are (a) undamaged and (b) able to completely close and fit correctly?

If that doesn't help, try the following trick:
