The zoom lens don't retrack Display don't

This camera has a 9mm lens, and while shooting, you can't zoom. For that you need a zoom lens. You can buy one from Samsung.
I checked the manual, and it also does not show how to zoom in on a picture when it is on the display. So I guess, you should view it on a computer, or tablet ant use the picture viewer on that device to zoom in.
Be aware you have a great camera and the result with a prime (one focal length) is superior to the results make with a zoom lens.
But if you don't like to move around, to farm the picture, a zoom lens can be convenient.

Typically means you have a jammed lens movement. Sand from a beach perhaps, or worn out. Get a replacement. Not worth the time.

In either mode, you're zooming by turning the zoom ring on the lens? In live view mode, if you zoom in by pressing the magnifying glass button, all you're doing is zooming the display, not the image itself.

That is shutter error code. I am sorry to tell you have to buy a new camera, it would be to expensive to replace.

There is no DYI fix for your damaged lens, and attempting to repair it yourself will likely cause serious damage to the camera. Professional repair is needed to fix this problem.

zoom wont retrack saying zoom error

Hi,
    As in short answer you have to replace the optical lens assymbly.Because due to heavy jurk its motor called sledge motor stsrt malfunctioning and it can not be changed component level. For this please contact any SONY SERVICE CENTRE nearby to you.
Hope you will understand.
Thanks for using FIXYA!

no the memory card is not the problem .... the internal gears or blocks which intialises the lens may have been dislocated due to which this problem is occuring ,..... it has to be fixed from a repairman ,....

Evidently the mechanism is damaged by a knock or dirt has entered the system. There is no self repair remedy Contact the HP customer support site for further advice

If the lens assy is not responding to zoom buttons then the camera is in confusion mode due to a sensor being blocked or defective. Normally it would go thru a startup cycle to initialise position of various parts in the lens assy and give back control to you but in your case it is not getting that signal and in your case I would bet on the end sensor.
