Im after getting my hands on a color cctv camera module with audio, and a wireless transmitter and reciever. When i went to try it out, the picture stays color for about 2 seconds, and then changes to B&W. To see if it was the transmitters fault, i dis and re-connected the camera to the transmitter and found the same problem happen again. I cannot see any visible problem with the pcb of the module.Is this a common problem? i would be very gratefull for any suggestions for ways to go about solving the problem.
