For me my camera turned on after many months of not working in between the OFF and ON button for a split second. (I think it got wet or something) anyway the way I fixed it was that i read on a forum somewhere that you should toggle the ON and OFF switch like 100 times when the battery was out then when you put everything back in SLOWLY move it from OFF and ON until you see a sign of life. I tried everything I could to fix my canon 60d that just would not turn on. Mind the flash capacitor! If none of this helps, it might be the circuit board. Shaking the camera and tapping with a screwdriver can remove the screw from the innards. » Canon EOS 5D Mark III, Nikon D800E 36.3MP () by dorome Tue Aug 19. 2015 10:47 am » for sale Apple iPhone 6 16GB.

Step four: If it still won't work or fails again shortly afterwards, remove bottom plate and see if one or several screws of the bottom circuit board (towards the handgrip or towards the CF card door) fell out. Canon has announced a new firmware update for its prosumer EOS 7D DSLR digital camera.
Carefully clean the two copper contacts with cotton swabs and alcohol. After that clean with cotton swab and alcohol. Use a screwdriver and slightly scratch any oxidations off the surface of the lowest, protruding part of the silver contact. In particular the silver one that is closer to the back of the camera.
Clean the battery contacts in the battery compartment. The update also enables the use of the GP-E2 GPS module. Step three: If the viewfinder is unusually dark, the camera gets no power whatsoever (the 7D uses polarizers for the viewfinder displays, such as the focus points to show up - these require a tiny amount of energy and if the power is gone for more than 4 seconds, the viewfinder will go dark - to test what I mean, remove battery, wait 4 seconds and look for yourself). Changes include improved continuous-shooting buffer depth (to 25 Raws, up from the original 15), customizable Auto ISO, control of audio recording level for video and the ability to re-process Raws and rate images in-camera. Clean the main switch with a strong air blower while switching back and forth (sand!). Use screwdrivers to check the operation of the microswitches. If no: The camera receives power but will not turn on because either the main switch, the microswitch of the battery door, the microswitch of the CF card compartment, or several switches are not working.
