Raspberry camera error: "mmal: No data received from sensor"

Question

I used successfully my raspberry camera times ago. Now I tried again to acquire a image with the raspistill -o image.jpg command; the red led on the camera flashes, but I get this error:

mmal: No data received from sensor. 
Check all connections, including the Sunny one on the camera board

Of course the camera connections are fine. Is there any other way to check if the camera is still working?

Answer 1

I was experiencing the same problem too, until I found a solution.

I removed the sunny connector(the yellow thingy below the camera in the board) and fixed it in the same place. The camera is working fine after trying this.
