Camera Won't Turn On After Putting New Batteries

It sounds like the blue substance you're seeing inside the battery compartment may be corrosion caused by leakage from the batteries. Corrosion can prevent the batteries from making proper contact with the camera's internal terminals, preventing it from turning on. Here are a few things you can try:

1. Clean the battery compartment: Use a small brush or a toothbrush and some distilled white vinegar or baking soda and water to gently clean the corrosion off the terminals. You can also use a pencil eraser or a q-tip dipped in the solution. Be gentle and avoid scratching the terminals.
2. Dry the compartment: Once you've cleaned the compartment, use a clean, dry cloth or a q-tip to dry it thoroughly.
3. Test the camera: Insert new batteries and try turning on the camera again.
4. Check the battery and battery compartment: Make sure that the batteries are fresh and in good working order, and ensure that they are inserted correctly.

If you are not comfortable with cleaning the compartment or if the camera still doesn't turn on after cleaning, it may be best to seek professional help or contact the manufacturer for further assistance.

There are a few potential reasons why your Canon PowerShot A550 camera won't turn on after putting new batteries in it. One possibility is that the batteries are not properly inserted into the camera, so double-check that they are securely in place. Another possibility is that the batteries are dead, so try using a different set of batteries to see if that resolves the issue. If the camera still won't turn on, there may be a problem with the camera's power switch or internal components, and it may need to be repaired by a professional.

Here are some troubleshooting steps you can try if your Canon PowerShot A550 camera is not working properly:

Check the batteries: Make sure the batteries are properly inserted and that they are not dead. Try using a different set of batteries to see if that resolves the issue.

Check the lens: Make sure the lens is not blocked or dirty, as this can prevent the camera from turning on or taking pictures properly. Clean the lens with a microfiber cloth if necessary.

Check the memory card: Make sure the memory card is properly inserted and that there is enough space to take pictures. Also make sure the card is not locked or damaged.

Reset the camera: Try resetting the camera by removing the batteries and memory card, then reinstalling them and turning the camera on.

Update the firmware: Check for any firmware updates for your camera on the Canon website and update the firmware if necessary.

If none of these steps worked, contact Canon support for further assistance or take it to an authorized service center.

Note: These troubleshooting steps are general in nature and may vary depending on the specific camera model. Kindly refer to the camera manual for specific troubleshooting steps.
