Lens will not Zoom in or Out

Our camera is like new. Was for gotten in its box for about 4 years ( no batts in it so no acid leaks ) Had only been used a few times. Never dropped or exposed to any dirt/water. When we power it up the lens extends to its normal position. Shoots perfect shots and video in its default zoom setting. If you try to zoom wide nothing happens. If you try to zoom In, the lens starts to move and then it pops up an error on screen that the lens cap is on (when it's not). Maddening because it's basically unused and brand new. I tried some tapping on all sides to no avail. Ive done all the resets I found online and reset to defaults. Any suggestions?
