I have been trying to take pictures but every time they come up on screen there's several black spots on the rear screen....

I recently bought a new battery for my camera but when I put it in the camera, it doesn't turn on. I have taken out the...

I went to go use my camera today and the screen on the back won't come on. The camera itself is on and it is not connected...

As my dad always said never over look the obvious, that being said do you have the correct battery? These camera batteries all look alike and it can be easy to pick up the wrong one. Now assuming that you have the right battery and it still doesn't work then that means its the camera and not the battery. Make sure that the battery slot is clear of debris on both the top and bottom. Something may be blocking the contacts. Another possibility is the door that holds the battery down could bad or worn away. See out replacement guides on how to replace that. The other issue could be the circuit board. Something could have shorted (something with power gets connected to something that should NOT have power, resulting in something getting fried. You can confirm this to see if there are black marks on the board.) or a component went bad. If either of these are the case then you might as well get a new camera, unless you can solder and find the component that has gone bad, which is rather difficult.

One problem is it could be a setting in your options. I do not know what it looks like so I cannot give a definite answer. But with the knowledge I have about this camera I can make an educated guess that it is an internal error. if you look at our replacement guides you can see how to take apart the camera. There are two possible issues. One is your screen is bad (we show how to replace that) second is you may have an issue with your lens. If you inside the casing you see a circuit board (that big green thing with all the strange technology on it) behind that is a black box (yes you will have to take the circuit board out. There should be three to four screws, be careful not to touch the top and bottom of the board, only the sides). This box is how the magnification works. There are lenses that slide back and forth depending on the desired zoom. This device could be bad or there may be dirt on the lenses. You should be able to wipe these clean. Hope this helps!

The best way to fix this is to go into your camera's settings under the menu button and turn on the display. Usually the camera turns off the rear display when connected to a computer so it may not have reverted back to its original settings. See the troubleshooting page for more detail.
