First, using the Reset option in the setup menu, reset the camera to the default settings. Unless a component or connector has actually failed, it may be as simple as dust or residue that has collected over time on the card slot contacts. Get a can of compressed air (Radio shack or an automotive store). Blow out the slot first with the air. This may dislodge any foreign substance blocking contact. If unsuccessful, use the alcohol to again clean the contacts on a memory card leaving it lightly wet, work it in and out of the slot and dry it after wards with the compressed air. The compressed air alone corrected the problem in 3 similar units, just this past month.
If unsuccessful, since your camera is new, it is still under Panasonic's 1 year warranty. There should be no problem having your camera repaired or replaced by using the contact information at the link below.
Please keep in mind that my diagnosis & solutions provided are directly
dependent on the accuracy of your description of the problem. As with
any "do it yourself" fixes, success is a "team effort", since I can't
see or touch the camera, and relies on the customer's manual dexterity
and ability to follow the instructions well.
