Be sure that the battery is oriented correctly when inserting. Refer to [guide|4914|this guide for details on correct battery orientation]. === Battery Power Is Low === Make sure that the battery is charged. The camera will not power on if the battery is low. Insert a charged battery, or use the optional AC adapter for the camera. === Motherboard Issue === If the camera will still not turn on, then there could be a potential issue with the camera’s motherboard. Professional repair may be required. [guide|4978|To access the motherboard, refer to this guide]. == Image Doesn't Appear on LCD Monitor == The camera is on and will take photos, but nothing is appearing on the camera’s display. === LCD Monitor Is Not On === The user has the option of turning the LCD monitor on or off. When the LCD monitor is off, the display will not show anything. Press the DISPLAY button to turn the monitor on. === LCD Image is Hard To See === Bright lights or sunlight will reflect off of the LCD screen making images appear dark and difficult to see. Try getting under a shaded area to see the LCD screen better. === Restart Camera === If the above suggestions do not work, try turning the camera off and then back on. Sometimes restarting the device will allow the logic board to recognize the LCD. === Disconnected Wires === If you have tried all of the suggestions above and the LCD screen is still not working, you may want to check if the wires connecting the LCD to the logic board are still connected. [guide|5008|To access the LCD screen, refer to this guide.] === Malfunctioning LCD === If the wires are intact and the camera works, but the LCD screen still doesn't show an image, there may be a problem with the LCD or the camera's firmware.

When the flash status lamp lights red and stops blinking, then the flash lamp capacitor is fully charged. You should then be able to take a picture. === Insufficient Memory === The camera will not take a picture if there is not a sufficient amount memory to store the picture. Check to make sure that there is enough space in the camera’s memory or SD card to take a picture. Delete any unneeded images and videos to clear up space. == Dirt Got Inside the LCD Monitor == Dirt or other debris got underneath the LCD cover. === Clean the LCD Monitor === [guide|4915|This guide will show you how to remove the back cover.] You can then remove any debris on top of the LCD or behind the screen cover by using a brush or other cleaning tools.
