Black screen after recharging the battery, i replaced into the camera, however, when i turned it on the screen remain black.

Sounds like a hardware problem... You may have to take the camera to a dealer and have them check it out. However, try this first:
Leave the card out for a while, and recharge it. Then reset the camera to factory defaults is you can (check manual).
You may also want to check with the Olympus web site to see if you have the latest firmware update to your camera model. You could try and download latest version and install it.
Hope any of this is to some help... :)

1. Ensure the camera is turned on.
2. If applicable, ensure the lens cover has been removed before taking pictures.
3. Ensure the LCD backlight is turned on by pressing the DISPLAY button several times until the screen appears. NOTE: Depending on the camera model, the DISPLAY button may be labeled as DISP or with a display icon [FIG. 1]. This button could be a standalone button or incorporated as one of the control arrow buttons depending on the model of camera.
   
4. If operating the camera with a battery, ensure the battery is fully charged.
5. Ensure the battery is inserted properly in the camera.
6. If operating the camera with the power adapter, ensure it is plugged into a working AC outlet.
7. Ensure no Audio/Video (A/V) cables are connected for viewing pictures on a TV; the LCD screen will not display when an A/V cable is connected.
8. Perform a reset procedure on the camera.

The troubleshooting steps listed above should resolve your issue. If you have completed all of the steps and the issue is not resolved, service may be required.

Try to reset the camera to original settings:
How to reset a Cyber-shot® digital still camera back to original factory settings. Solution
Cyber-shot cameras nowadays have a built-in rechargeable battery for retaining time, date, and other settings. Since the built-in rechargeable battery is not removable, current Cyber-shot camera models can only be returned to the original factory settings by pressing a small RESET button on the camera or by using an Initialize option in the menu.
Older-model Cyber-shot cameras (prior to the year 2000) do not have a built-in rechargeable battery and do not have a RESET button or Initialize option in the menu. These cameras require a manual power reset.
IMPORTANT: To determine whether or not your camera has a RESET button or Initialize option, or for other model-specific information to complete any of the steps in this solution, refer to the operating instructions supplied with the product. Manuals are available online in the Manuals/Specs/Warranty section of the Sony® eSupport Web site.
Follow the appropriate procedure below for your camera.
Using an Initialize option in the menu
Since Cyber-shot cameras have different menu system layouts, refer to the instruction manual specific for your camera model.
Using a RESET button

1. Locate the RESET button on the camera.
2. Use a pointed object (like a ballpoint pen) to press and hold the RESET button for 2-3 seconds.
3. After 2-3 seconds has elapsed, release the RESET button.

Performing a manual power reset

1. Turn off the camera.
2. Remove the battery pack.
3. Remove the button-sized lithium battery.
4. Allow the camera to remain without power for 30 seconds.
5. Reinsert the button-sized lithium battery.
6. Reinsert the battery pack.
7. Turn on the camera.

its just a matter of batteries...some are not powerful enough to operate the camera ....Try to change them and buy some real good ones..like Duracell or Tatra...do not make any compromises when buy the batteries...get the best cause these kinda cameras really require powerful ones...or ...try to get a set of rechargeable ...

The camera needs battery when connected. Please use lithium batteries Ni-Mh or rechargeable Batteries (2000 M.Amp or higher).

NOTE The cameras LCD screen will remain black throughout the transferre.

If you're experiencing that the computer is not reacting to the camera at all try the following:

Remember you need to turn the camera on when transferring.
Try a different USB outlet
Try a different cable
Try a different computer.

If all fails please contact KODAK in order to arrange a repair or order a new cable. Remember your USB cable is covered under the same warranty as your camera, so remember your serial number when calling:

That's what it would do if the battery had no charge. Batteries can only be recharges so many times. Pick up a replacement battery. If that doesn't solve it, at least you'll have a spare battery.

Hello,
Are you installing Nmh (Nickle- Metal Hydride) rechargable batteries?
If not then your camera probably will not recharege them.
Also trying to recharge non rechargable batteries can cause damage to the battery, and possibly your camera.
Hope this is helpful.

Had the same thing happen to me a month or two ago, Battery recharge is taking up all the current flow for a period of time. Leave it alone for about 30 minutes to recharge, then you should be able to operate the laptop again, but will have to remain hooked to outlet power until battery is fully recharged.

It is possible you have the display turned off... Some cameras allow you to do this to save battery.

tuen on camera then press display a few times. it sounds like the display is just turned off. the lens system should be open.

the (Access) in the screen refer to one of this problem, the lens mechanism is unable to start due to plastic broken parts in it or dust, or battery poor power, use a rechargeable battery over 1200 uAh of power
