Hello, Sorry for my poor english... I just buyed an second hand STX 16803 and I have a problem I can't resolve. When I plug the CCD in my computer, the SBIG device is recognized in device manager (w7-64) but I can't connect the CCD with CCDOps. When I try to connect with SBIGDriverChecker64, I can't stablish the link. The drivers are correctly installed. When I plug the power cord, the fan starts but stops after 5 seconds. It is the same thing if I plug the USB cable to my computer or not. I live in Switzerland, would you have a solution so I don't need to send back the CCD to a repair center ? Do you know if there is a repair center in Europe ? Thank you and regards, Miguel
