回答先: Why does my flash not work properly?Hi Jose, There are a number of reasons why your flash might not be working. First, make sure your flash settings are properly enabled when using the camera. If that isn't the problem, make sure the flash connector is properly cleaned so that a good connection can be established. If there is too much dust collected, use a cotton swab to carefully clear it off. Also make sure that your battery is charged; the flash will not fire if the battery is too low. If none of these is the problem, your flash bulb may be burned out. Please refer to this page for help replacing it: How to replace your digital camera flash bulb
回答先: Why is my HDMI Port not working?Hi, Geremy. First, check to make sure that your connecting cable is securely plugged in at both ends. If that does not fix the problem, try gently cleaning the ends of the HDMI cable and your camera's HDMI port with a cotton swab. If neither of these solutions are successful, it is possible that your camera needs a new HDMI port.
