I took a picture while my Panasonic Lumix DMC-ZS10 was connecting to PC and now it will not connect to my PC. I’ve tried taking the battery out, restarted the computer, turned off/on camera. Nothing works. This error flashes when I try to connect “Picture is displayed for 4:3 TV for 16:9
It is really not an error that flashes. That is the output setting that is detected whenever the A/V cable is detected. I would start by resetting the camera to the default settings. Go to your setup menu and use the reset functions. You can also try to set it to USB first and see what happens. If you do not have the manual, download it from here.Hope this helps, good luck.
