Re: Can I use electronics cleaner (in a spray can) to try...

Absolutely no! Apart fron the dust/grit problem, the electronics cleaner is probably not very clean itself, and may contain all sorts of ingredients in the formulation! If you really must use a spray wash, then IPA (Isoproply Alcohol) is best. The sort you get from printer shops for cleaning print heads is usually very pure as otherwise it could clog the fine jets in the head! Otherwise your best option is to disassemblr the camera, but watch out for high voltages stored on flash capacitors. They still bite after the batteries are removed!

Under no circumstances should you try this, as you know that sand is present. the liquid will drain the sand deep inside the lense assymbly and would create mode friction to the movement.

Re: Can I use electronics cleaner (in a spray can) to try...

HP put out an update which can be downloaded from their site, to correct this problem. They state it's a software problem in the camera itself.
You might try powering the camera off, then restart it to see if that might help. With camera off press and hold the on switch until the logo appears, then immediately release it. Reopen the camera and follow the inquiry's which will come up on the screen.
Watch the lower left hand of the screen and see if an error message pops up momentarily, The format would be "Error 108."
You can also e-mail HP tech support and they will try to help you at no cost.
If you read their forum pages, it looks like everyone who bought this camera has a stuck lens.
As a P.S. I never have gotten mine to work again and I'm told it will have to be sent back to HP for a total re-programing. No idea what it would cost.
Good luck if you find a solution let me know, I'd appreciate being able to fix mine.

I know this is an old post but it may help someone. Blow lots of compressed air in there to clean the mechanism. Also with the lens barrel extended, tap it with a pencil (a grain of sand is usually the culprit, this may help to dislodge it). If that doesn't work, it may be necessary to go in there. Do this only as a last resort. The following repair will likely expire your warranty, so be forewarned. This blog post outlines repair procedures for stuck lens covers. An A400 is used as an example:
Good luck, and remember to do this only as a very last resort. Oh, and if you do decide to try the repair, please post how it went.

NO I repeat NO liquid should be used anywhere near the lens assembly. It will cause further problems and streaking on the lenses. Sometimes clean and dry compressed air will do the job but to make sure it's all out a complete dismantle and clean is needed. BMW

How do I open the lense cover

the sliding type lens cover is not so easy to remove, you have to open the whole camera, then remove the front portion of the body then it is easy to dis assemble.
dirt or sand go in side this will obstruct the lens, use contact cleaner spray to loosen this, be care to fix the magnet in which is helping to switch the power on when this cover slides.

The lens is stuck, it doesn't come out

Hi, This is a very common problem with digital cameras. The lense is a very complicated piece that has motors sensors focus motors that can see clearly at a distance or close or in between. So any rough handling or trying to open lense in a case or pocket by accidental getting its on button pushed is a death sentence for lenses on digital cameras, dirt sand etc getting in the conical tube setup is not good either, they CAN NOT be mishandled if you think that that bump the camera got wasn't that bad the lense will have the final say and odds are it will say NO. Final thought is it's broke so try wiggling the lense with you fingers,tapping gently on a hard surface if it don't fix it it is still broke and probably to expensive to repair.

Won't turn on

Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

The optical zoom moves in and out everytime you try and turn it on then it says lense error

It's focus system problem - most likely stuck. Could be sand or some dirt inside focus gears. They're very small for these lens which are used in many Nikon, Olympus, Casio and other cameras so even one small piece of sand can block the focus system. The only way to fix it to take the camera and lens apart and clean it.

Sorry for the bad news. I repair cameras every day and you can trust me - I know what I'm talking about.

Lens will not extend


You need to clean around the lense first. Blow high pressure air spray and get the most sand out of the lense you possibly can.

If it did not open 100%, try to pull it out NOT too hard. If the lese goes up and down and turns you should follow the lense while pulling it out.

When it is 100% out, (the way normally opens) Clean around the lense more.

Turn you camera on and off a few times. It should be back to normal.

GOOD LUCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

In the screen says lens error

Hi I had the same problem with a codak C743. I cleaned the lens casing from out outside as much as I could and sprayed a tiny bit of WD40 making sure not to get it on the lens itself.

Then I kept turning it on, and zooming in and out until I got the lens error message, switched it off, the on again, wipe, new WD40, zoom etc. repeated this s number of times until the lens was freed.

I think I had some sand/ dirt around the casing.

Worth a try I guess.

Panasonic DMC-FZ7 digital camera.

I believe the FZ7 determines that the lense cap is still on when it can't extend the zoom lense because the lense cap is in the way. I would check to see if your zoom lense housing is somehow stuck (could be sand or dirt in it) which is creating enough resistance to make the camera think the lense cap is impeding the zoom lense from extending.
