This most likely is a power issue, please check the following:
-If using internal batteries, make sure there are 12 new AA batteries, preferably lithium ion
-If using a solar panel, be sure the panel is fully charged and there is a good connection on both ends
Please note, there is a red LED that will flash repeatedly when the camera is in setup mode. When the camera is powered on, the internal LCD screen will go black and the red LED light on the outside will flash up to 15 times before sending a status report.
-If the red LED is flashing when in setup mode, but the LCD screen is not turning on, there may be an issue with the LCD screen.
