Canon EOS 650D the red access light flashes when camera turned on for 20+ second, then goes off. Also everytime when a photos is taken the same. I've taken out SD card, replaced it, removed battery, done a factory reset on camera. SD card works in other camera.

SOURCE: Why do I get Error 99 in my Canon EOS 350 D?

1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If it does, then the camera should be
serviced. If it does not, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.
If the message does not appear, please complete the following steps:
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99′ message only appears when one particular lens is
attached, then that lens should be examined by a service technician.
If you see the “ERR 99′ with a different Canon lens attached, then the
camera should be serviced.

SOURCE: Busy light comes on when I start the camera

Had the same thing happen to me, took the batter and memory card out then tried to turn it on (With no batter nothing was going to happen) left it in the on position for an hour replaced the batter and turned it on. Which worked for me (problem has never come back).

SOURCE: canon EOS 400D will not power up

Generally a fuse blows on these, on the DC/DC converter (psu ) board. This is situated on the front of the camera, fairly easy to get at just involves undoing loads of screws!! The fuse is marked "K", replace or short out with a thin piece of wire. May be caused by changing lenses with the power on, but not sure.
Watch for the charged flash capacitor though!!
Had this problem with mine.
