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.

Brilliant ! Had the same problem with my DMC-TZ60 and tried your above solution. Immediately all good and working well. Thanks

par

Crikey!! I've just done exactly this and my TZ60 is operating properly again. Astonished, and thank you :-)))

par

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.

Solution retenue

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.

par

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.

Thanks, that fixed my zoom problem.

I have a PANASONIC DMC-TZ71. It had all problems described. Zooming started videorecording. Zoom going in wrong direction, or totally freezing. I sprayed contact cleaner "KONTAKT 60 Reiniger" into the tiny crevice around the zoom ring and shutter button. This was the solution - Fixed everything.

Thank you so much. I bought a DMC-TZ71 which was not in use for long time and it had all the problems as descibed. After reading your advice I bought the "KONTAKT 60 Reiniger" and sprayed as you described. After very short time the zoom lever is working fine.

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.

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.

Hi

I have the same problem with my Lumix. Do you have an update about what is happening now to your please ?

Hi,

Since my last answer some further changes have occurred. The replacement of the PCB was only a temporary solution. The same problem is there again. I have abandoned using the camera, even if it still shoots very good photos when zoom is not required. Two persons in the chain have had good results by using Kontakt 60 Reiniger. Is wd 40 something similar? There are also risks in using chemicals, but if you are ready to take them, you could at least try. Use a very small amount of the chemical at least to start with.

No, I would NOT use regular WD-40 as a contact cleaner on electronics. It will leave an oily lubricant on your contacts. However, the WD-40 company (and others) makes a quick-drying contact spray cleaner.

Arrived here googling "Lumix DMC-ZS25 video initiates while zooming". Love this camera found at a thrift shop for 1/10 the original MSRP, Leica lens to boot ! Building on Peter A's and Joachim P's suggestions, carefully sprayed DeoxIt F5 (L spray setting) around the zoom ring, working it back and forth several times and then using canned air to remove / blow extra F5 out. Done with battery removed. Repeated a couple of times and the ZS25 Lumix functions as new. Worked so well, repeated this procedure on the Mode dial. This feature laden, compact point and shoot accomodates an extensive range of shooting conditions and complements the phone cam. Slowly R(ing)TM (advanced) and learning all capabilities. Thanks again to contributors to this topic.

Excellent utoob by mikeno62 dismantling a Lumix TZ100 and detailing the zoom ring assembly and zoom trigger switch @ 51 mins in. Guessing the F5 and blast of canned air is enough to penetrate to and clean / lube the trigger switch. Good luck to all.
