starts recording video when I zoom in

I've had this for a while, and cared for it well, so it has not been damaged. Now *most of the time* when I push the zoom button to 'T' to zoom in, the camera starts recording video. I thought maybe there's a physical problem on the PCB, since the buttons would be rather close. I opened it up and everything was in place and felt right, no sticky buttons or whatnot. Putting it back together did nothing to improve or worsen the problem. I'm no pro photographer, but this is a nice little camera, I'd hate to see it go.

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.

I found also a service manual online here: http://www.csportal.panasonic-la.com/des...

When you look at page 58 you can see that the zoom function is combined with the movie recording button. You can even conclude that a bad contact in the "tele lo" (=zoom in slow) can result in a movie recording signal for the electronics.

So to clean that zoom button contact you can even move it a a while without switching on the camera. Especially the area from neutral to "zoom in" (= move to the right side) and back to neutral.

It helped with my device.

Let me know if it helps

BR, Peter

this is the best and only solution I have found, thanks for the advice. it seems a very temporary fix however: I have to remember to wiggle the zoom rocker every time I go to turn the camera on. this *generally* works. I have lost many opportunities to get time-sensitive shots due to this faulty design. thanks for your help.

Yes, this helps but only temporarily -- if I remember to wiggle the zoom control before turning the camera on. I can then usually get a couple of zooms in before I'm back to the zoom control switchin on the video. Perhaps I will open the camera up and see if there's anything I can do to clean the contacts, or stiffen up the action of the lever, or something! Seems like this is something I'll have to live with. Too bad, as it IS a lovely little camera -- mine has the Leica lens and can create some wonderful pix.

Wow! thanks for that fix.

I have the same problem with a tz30 lumix

Could you solve it?

I still haven’t found a fix, sorry. I even took my camera apart to look for some hardware button malfunction. It all looked in order, so I put it back together, problem persists. I’m tempted to physically destroy the video record button...

oh and “Ricq Maroni” is me, Patrick Schoolcraft. I guess I have multiple accounts here...

It's strange now...the camera is working almost perfect now. What I did was zooming it in and out to maximum for 20 times or so.

I have the feeling it's not related to the rec button itself. Maybe it's the zooming mechanism that goes tougher and causes a voltage drop in the system making it think another button is pressed? Maybe after zooming it a couple of times makes it work more smoothly? I have no explanation otherwise.

Try the zooming ... and see if it improves? BR Peter

I too have just experienced this issue on my Lumix TZ70... and amazingly the above does seem to work.

I did multiple zoom in and outs (well over 20 times) and now the problem seems to have disappeared.

Well see if it is a permanent cure, but at least it has done the trick for now.

Thank you for the suggestion!

I, too, have this problem, with a DMC-TZ40 I bought back in August of 2013. I have a leather case in which I always carry the camera. -- The issue has been causing quite a pain for at least two years now, and I have already lost several recordings on that account: Unaware that the camera has already started recording, I press the record button when I intend to start recording, then press it again when I intend to stop recording. That way I get a blurred recording of the focusing phase prior to when I actually intended to start recording, and a nice clear recording of my feet from after I intended to stop recording!! I know I could look for the blinking red on-screen recording indcator, but my eyesight is not perfect, and I forget being aware of whether the blinking red dot is there or not.

I have found no solution the problem, and this is primarily intended as a contribution towards the documentation of the problem.

However, any suggested solution would be welcome.

Peter Audenaert’s solution to wiggle the zoom rocker before powering on seems to reduce the issue in my camera, not a 100% fix, and not 100% success, but in my experience, it’s an improvement. hope this helps.

I have this same problem on a Lumix TZ70 and its been driving me nuts. I mentioned it to a friend who called in from Scotland the other day and she said she had the exact same problem! I had tried waggling the zoom lever to see if that helped but I’ll now try doing so for longer and keep my fingers crossed. Otherwise it will be back to Panasonic for repair under warranty.

Hi Mike. Please let us know how it goes/went, if you return(ed) it to Panasonic for repair. We are probably all eager to know Panasonic's explanation and cure. Thanks.

Hi - Yes, the waggling zoom button trick did not really work so I sent it back to DK AVS Horley Ltd, Panasonic's UK repair agent, for free repair under 5 years extended warranty. they stripped down the camera to replace the flash/top PCB and Lens Master Flange. So far seems to have fixed problem. Lens Zoom also seems more positive. Camera was only away about 4 days, so maybe worth getting a quote even if not under warranty.

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…

Update (03/20/2019)

Hi Patrick,

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.

QUESTION…Do you turn the camera off after the max zoom (Telephoto)? (When I reverse to Wide, the video turns on.) Or do I turn the video off, go to wide angle and then zoom again?

Hi. I have a Lumix DMC-ZS15 with the same symptoms as described by many people before me. I tried both of the methods; I blew hard on the shutter switch and the zoom ring several times (compressed air would have been better, but wth) and I turned the zoom ring back-and-forth about 25-30 times. The pronlem seems to have gone away, at least temporarily… Now, being an electronic engineer with a lifetime love affair with mechanical switches, this does make sense a bit: most likely it is a build-up of grime on the switch contacts that may be cleaned up by repeated activation. If, however, the malfunction is related to ageing of the contacts, the symptoms are expected to return with a vengeance, since the rapid activation causes more wear and the worn contact surfaces are more likely to gather more grime. I’ll be curious to see which way my beloved DMC-ZS15 will go. I think it is one of the greatest P&S cameras ever made, and I have used quite a few. It’s difficult to find one even on the used market. Cheers.
