Such symptom indicate a malfunction o the DC/DC voltage converter circuitry, and the camera has two of them located in different boards.

In order to perform a correct diagnostics and repair of it, it is necessary to open such camera and perform it by a qualified camera repair technician.

If it's under warranty, I do recommend you to send it back to make valid the warranty.

If not, then you hav the options of pay for its repair, or do it yourself if you are willing tgo open it and perform some basic diagnostics of the failure. You will needtools to do it, which includes the usage of a soldering iron.

Best regards,

Check/replace the battery inside the remote. Check the battery of your vehicle. The battery connectors could be loose. untill you unlock the vehicle with the remote it will not start. try resetting it by removing the +ve positive connector from your vehicle battery for a few minutes.

Sorry to hear about this. I have a similar camera and have been racking my brain about this...

My only thought...are you using the same battery charger? Perhaps the battery charger is to blame. You may be out of battery on both batteries. When you install the battery, does ANYTHING happen? Does it say, LOW Battery or CHANGE the battery? Or is it totally black? If nothing happens at all, you should probably contact Canon directly. Or purchase a new charger and see if that fixes the problem.

Canon EOS rebel XTi won't turn on. Changed batteries several times still nothing


Mcm,
Trying taking a Q-tip with some alcohol and cleaning the contacts inside the battery chamber. Also, you can take it to your local camera store and ask them to try it with one of their batteries to rule out if yours is dead.

Thank you.

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.

Your problem may be due to weak/worn out batteries or corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera. This cleaning clears the problem about 90% of the time. If it doesn't work for you, your batteries may need to be replaced, or the camera may have a problem that requires professional repair.

There could be dust or other foreign objects in the battery slot, you might need to clean it out. If not, I would advise that you may need a replacement battery
