The backlight inverter board may have gone out, or power supply for the inverter is bad. Check the power supply first since it is easier to get to. Look for bad capacitors, etc.

Monitor goes black after a moment


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Canon A700 black screen when i want to take a picture


Did you accidentally press the DISP or DISPLAY button on the back of your camera? This button manually turns the LCD display on and off to save batteries. Pictures will still appear momentarily when shot.
