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.

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.

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.

I have a Phillips combo dvd/vcr - all of a sudden when I put a VCR tape in, the word ERR is displayed and tape won't play. It has now eaten 1 tape.

Most likely the mode switch in the VCR has either gone high resistance, and will need to be replaced, or it is probably dirty, thus it can be cleaned using electronic cleaner (assuming the mode switch is a rotary type encapsulated in a plastic casing (some VCRs incorporated a sliding mode switch - such as National in the early 1980s) - a spray cleaner/lubricant may do the job - not expensive - this cleaner should be available from most leading electronics/hobby stores off the shelf).

The downside is the cleaning of the switch (which should be under the VCR mechanism and soldered to the motherboard) cannot guarantee long-term reliability, so the switch will have to be replaced (this could be tricky being Philips/Magnavox) - but try cleaning it first - this is cheaper and you don't go without a unit for a long time. I hope there are no tapes stuck inside the unit.

In this case, I strongly recommend that you try and clean the mode switch with electronic switch cleaner - it comes in an aerosol spray can and is not expensive. You may need to look around for the appropriate type of cleaner as there is more than one available. CRC is the best bet according to technicians. CRC is a spray electronic cleaner/lubricant - so it will also lubricate the switch contacts as well as clean and remove oxides. Do not use supermarket sprays such as WD-40, or automotive sprays such as ArmorAll.

I do not recommend removal and disassembly of the switch itself to clean it unless you are tech. savvy with several years' experience, and you have some understanding of its alignment in relation to the mechanism. If you are careful, and with the unit unplugged from the wall, you can remove the VCR deck to gain access to the switch on the board and carefully apply the abovementioned cleaner, rotating the switch in both directions gently, to work the cleaner into its contacts. Let it sit for a few minutes, then re-fit the VCR deck, and reassemble the rest of the unit. Plug into power, and test a tape. This simple method should work (you won't need to remove the motherboard to do this, just the front panel and VCR deck) and it only cost you a can or two of contact cleaner at most.

You should not need a new unit.

How do you remove and clean the Mass air filter on Montero 03? received code p0174..thinking the sensor is dirty and needs to be cleaned.

MAF (Mass Air Flow) meter sits in the collar in the air ducting after the air filter/cleaner housing. It has a plastic box on top to which the electrical multi-connector attaches. Disconnect the plug and remove the MAF housing from the ducting. Use electrical cleaning spray only. Carb choke cleaner will be too harsh. Electrical cleaner spray can be got from any electronic retailer such Maplin, RS components or Radio Shack etc. Not only is this an exceptional solvent cleaner it leaves absolutely no residue. Spray the MAF element (foil) and allow everything to dry. Avoid the temptation to touch the element as it can be easily damaged. Only if absolutely necessary should you use a cotton ear bud and rub very gently to help remove stubborn dirt, always use plenty of spray and use a clean tissue beneath the MAF work area to catch drips and assess the degree to which dirt is being 'washed' away. Before reconnecting the MAF check the connecting pins in the plug and corresponding socket for signs of any dirt, a quick squirt with the electrical cleaner should help here too. If there are signs of corrosion rub the connections with some wire wool to ensure a fresh metal to metal contact.

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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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.
