No power Camera was not dropped or damaged. Hit the power button and nothing happens. Batteries are in correctly any ideas.

Your camera will work with AA batteries.
Always be sure the batteries are charged.
Insert the batteries correct plus to plus and minus to minus. Only one battery the wrong way around and the camera won't work.
Check contacts of the batteries and in the battery compartment of your camera. Dirty or oxidised contacts can be cleaned with a dry cloth. Never use sharp tools to clean contacts or anything in or on your camera.
Always charge the batteries before using it for the first time, or if you have not used it for a long period. 3 months is a very long period.
Also check if the battery door is closed correct. Most cameras do have a switch connected to the battery door. If the switch does not work correct, it could be you can't switch on your camera.
Do not use alkaline batteries unless it is absolutely necessary. In most cases, alkaline batteries have a shorter service life than NiMH. Alkaline battery performance is limited, especially at low temperatures. The use of NiMH batteries is recommended.
Never use manganese (Zinc-Carbon) batteries in your camera. They can't deliver enough power and can start leaking, causing damage to your camera.

Check the contact in the batt compartment for obstructions or corrosion etc. No power means broken circuitry - either physical dislodgement of electronic/ electrical parts or damaged electronic components.

Have you tried cleaning the battery contacts inside the camera? The problem that you describe is frequently due to a corrosion buildup that prevents the full power of the batteries from flowing to the camera. 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 the cleaning, then wipe both ends of the batteries and reinsert them into the camera. This cleaning clears the problem about 90% of the time, and I hope it works for you.

If you have recently dropped the camera you may have damaged the lens tube (housing). This damage will prevent the lens from moving properly and will cause the camera to shut itself off after a few seconds. If the lens is damaged the camera will require professional repair. If the lens is not damaged, the problem may be battery related. Make sure that you have the correct battery type installed, and that the batteries are fresh/fully charged. If the problem persists, you may have corrosion on the battery contacts inside that camera that is preventing full battery power from flowing to the camera. Remove the batteries and wipe the inside camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sand paper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and reinstall them in the camera. This cleaning solves the problem about 90% of the time, and I hope it works for you.

You probably blew an internal fuse , get it checked by a professional. No user serviceable parts on this camera.

Try another set of batteries

Remove the batteries & press and hold the button again for 60 seconds. This will ensure that the capacitors in the unit fully discharge. Replace the batteries in the correct sequence and try to power on the unit again. Without further information (was the unit dropped, immersed in water, were the batteries ever put in incorrectly) I cannot offer you another solution.

I had this same problem with my camera a few years back and took it into a camera store to get it fixed. It turned out that it was just the batteries I was using. You cant use regular AA batteries for this camera because they give too much power. If you just go to a walmart or target or anywhere like that, you can get AA camera batteries and that SHOULD solve the problem. let me know if that works.

I thought the batteries had worn out because when I press the 'on' button the 'busy' light comes on for a few seconds and then goes out and nothing happens. Have changed batteries and checked installed correctly.
Any ideas please?

Hi,
If the Olympus is using the exact same batteries as the Canon, there is a high chance that the problem is with the batteries.
