I have the same problem with TZ40. As Peter has already written, the reason for this strange phenomenon is that the video button is connected to the same resistor chain as the zoom lever switch. In TZ40 it is possible to zoom using the “buttons” on the display. This, of course, is not as handy as using the lever, but it does not start video recording. I do not know if this is possible in ZS25.
I also tried the trick Saul presented, and it seems to work in my camera as well. It is a bit difficult to understand why, but does it matter…
in my DMC-TZ40 I had the same symptom. Blowing seemed to be some kind of temporary solution. I am not sure about the mechanism, maybe it somehow makes some switch connections better for a time. The actual reason of the problem is the way the moving of the zoom ring and video recording are detected in the camera. It is analogue. There is a chain of resistors in the camera. One end of the chain is earthed. Apparently a constant current is fed to the chain, and the voltage in the not-eathed end of the chain is sensed. Turning the zoom ring or pushing the video button connects a different point in the resistor chain to earth. This solution makes the mechanical construction easy. Via only one connection to an IC the position of zoom ring and pushing of video button can be sensed. I got a solution to the problem by buying the PCB where the contacts and resistors are placed, and replacing the faulty unit. The PCB had name Top P.C.B. It was not very easy to purchase the unit, to say nothing of replacing it. But now the camera works again.
Cette réponse est-elle utile ?
When I read that the problem of the zoom starting the video recording may be caused by dust and moving the zoom button right and left did not work in solving the problem I tried the following:
I placed my mouth over the button that takes the pictures and the zoom lever and blew into the button. Right now, my Lumix DMC-ZS25 is working properly. This may have cleared what ever dust may have been making contact with the switches.

Brilliant ! Had the same problem with my DMC-TZ60 and tried your above solution. Immediately all good and working well. Thanks
Crikey!! I've just done exactly this and my TZ60 is operating properly again. Astonished, and thank you :-)))
This is a ridiculous solution... but it wotked! Thanks for sharing this and saving my beloved little DMC-ZS50 pocket superzoom..
I have a lumix zs40. It had all problems described. Zooming started videorecording. Zoom going in wrong direction, or totally freezing. I sprayed contact cleaner into the tiny crevice around the zoom ring and shutter button. Fixed everything. Here's what I used. DeoxIT Gold Mini-Spray, 5% Contact Conditioner. Bought on Amazon.
