Answer to "LCD screen isn't displaying?"If your LCD screen isn't working, there's either an issue with the screen itself, an issue with the connection of the LCD to the motherboard, or a battery issue. If the battery is at fault, a new battery will be needed. To know if this is the case, try charging the camera then turning it on. If the LCD is still not working the issue might be somewhere else. If the LCD has a bad connection to the motherboard, you'll have to tear down the camera and reconnect the screen to the motherboard. If neither of these solves your issue, a new screen will be needed. There are guides on this website that'll explain how to replace batteries, screens, and check connections to the motherboard.
Answer to "My camera's lens will not extend?"Hello again, Willard. I'm glad you decided to not trade it in, because this issue can definitely be solved, and it'll be cheaper than a new camera! First, shut off the camera. Turn the zoom button all the way to the right or left and hold it in place for approximately 5 seconds. Release the zoom button and then turn the camera back on. This should retract the lens and it should work at that point. If it still doesn't work, you might want to replace the lens itself.
Answer to "Camera won't turn on?"Try plugging your camera into the charger and ensure that the charger works. To check if the charger works, try using it on any other device that it is compatible with (microUSB is compatible with almost every electronic device). If the charger isn't working then your issue is with the charger. If the charger works and the camera still won't turn on, try to replace the power docking port.
