Hi Kris! One thing that you can do is ensure your television is set to the proper HDMI port the camera is plugged in. Enable HDMI viewing on the camera to see if pictures show on your television screen. If no images appear, plug HDMI cable into another HDMI plug on the television and repeat the process. If the image still has not appeared on the screen, replace defective HDMI cable. Sony Cyber-shot DSC-HX9V Troubleshooting Hope this helps!
