I've been using PI for over 3 years with no major issues but I am now having an issue with my RGB images. My recent images are remaining B&W despite using channel combination as I always have to get a color image. I also tried using APP but got the same result. So, it appears to be hardware issue and not a software problem. I have a permanent setup with a ZWO filter wheel and an ASI2600MM Pro camera and nothing has been changed for a few months. The individual RGB frames look fine but I can no longer get color when combined. I thought maybe the FW was not turning but I believe it is. Both the camera and the FW are connected to a powered USB hub on top of the scope which run down to the computer. All other accessories connected to the hub are functioning properly. Any ideas what could be causing this? The camera itself or a cable issue from the camera to the hub?
