Hello, @cesarm56044. Were you able to playback with both pictures and sound on the camera yesterday? If you haven't yet, try a manual firmware update.
First, make sure that the SD card is inserted in the correct slot. For the update process, please save al contents of your SD card as the update will require the card to be formatted. Doing this will erase everything on the card.
The steps under Manual Update here will guide you through the process. Make sure that the camera battery is fully charged prior to the update. Let us know how it goes. Thanks!
