I dont connect the lens to board but i do inly with LCD, and then I turn it on.

  1. The welcome music approached.
  2. LCD is blank.
  3. The orange LED on the board, near the LCD plug, is blink, and there is BEEP sound
  4. The camera is automatically turned off. … Thank you in advance

Maybe the battery is not fully charged..

sutakornfanpraew connect the lens if you expect to see anything on the camera. When the lens is disconnected the camera “sees” that as an error.
