Question about Sony Cyber-shot DSC-HX20V 18.2 MP 20x Optical Zoom Ultrazoom Camera 8GB

1 Answer

How can I remove dust from the lenses?

I've already paid to have it professionally cleaned. They said it wasn't covered by the warranty and I paid close to $300 only to have new dust settle in there in a few weeks. I carry it in a case and I'm not subjecting it to abnormal conditions. I've tried the vacuum trick, but it didn't work.

I checked the web and there seem to be a few people experiencing dust issues with the Sony Cyber-shot DSC-HX20V. Perhaps a strongly worded letter or email to their customer service might help, citing the fact that there are others with the same problem. Dust will get onto a camera's image sensor (DSLRs are subject to this - changing lenses and exposing the sensor), although with a fixed lens camera, I would think (do not know) that dust issues should be minimized. Anyway, best of luck!

SOURCE: Cleaning the inside lens

To access the inner optics on these compact digital cameras the lens must be disassembled from the inside out. Usually the camera casing has to be removed, boards and connections moved out of the way, and the lens assembly actually removed from the camera. At that point the lens can be taken apart and the inner optics accessed. In other words, yes, this is a job for a professional. It is also probably not worth the cost just for a couple specs of dust. These lenses are not sealed. This is why the dust gets in there to start with. If you get a can of compressed air and carefully blow into the gaps between the lens parts in different directions somtimes you can get enough air through to blow off the inner lenses. This does not often work though. David Millier Advance Camera Repair

SOURCE: Lens cover closed

this is easy to fix. in fact, i just did it on my camera about 2 minutes ago and came back to this post because i was originally looking for a solution myself. anyway, you have to be a little bit rough with the camera to fix it. on the outer lens cover you will notice that there is a metal cover on top of the plastic slider. you need to pry the two apart. there is some seriously sticky tape that is holding the metal cover to the plastic, so you need to be careful that you don't rip the whole thing off. once inside you will see a copper contact that (when you slide the lens cover) makes contact with another piece of metal. when i took a look at mine, it was covered in a bunch of lint. i used a q-tip to clean both contacts and then made sure that they were properly aligned. after that, i slid the lens cover back down and voila! works everytime now. use some superglue to put the metal cover back on again.

How can I clean out the inside of my lense?


dont worry about dust too much unless it actually affects your image sensor.check it by pointing to a white wall or sky with f put to it maximum like 32/22 , focus and take pictures.. if its problem with the lens then it will make prominent dark speckles on the image.. but if you get dark speckles even at lower f - stops like 1.4/3.5/5.6 then its dust in the sensor.

dont try cleaning your sensor yourself as you may spoil it and finally have to refer a service center of the brand .

I changed a cartridge but the print is still very light


Hi,
I received a similar HP Laserjet Color Printer with same issue for repair/ maintenance.
Actually the problem is with the printer design not the cartridge and it needs professional hands for servicing and cleaning. The mirrors which reflect laser beam get covered with dust and toner. Laser beams are partially reflected due to dust. Hence the image is not produced properly. Note that first magenta goes off, followed by yellow, then cyan and lastly black. this is because of the mirrors placement inside the printer.

Rest assure that the printer requires ONLY CLEANING OF THE MIRRORS, which are inside the printer. For cleaning, the printer's outer covers are required to be removed to reach the inside laser unit, mirror and lenses, which requires professional expertise.

Clean them yourself with dry, soft, lint-free cloth (if you are familiar with such tasks) or get it cleaned by any printer repair/ service professional. Please note that the mirrors, lenses and scanner assembly inside such printers is extremely complex and can get damaged very easily especially the mirrors.

If you need any help in cleaning mirrors and lenses let me know

Hope it helps! Good Luck! Thanks for using Fixya!

My panasonic Lumix DMC-ZX1 shows 3 dark spots and 2 hairs on all pictures. When I zoom-in the dirt is more visible and when I zoom-uit I dont see the hairs any more and the dark spots appear wider and...


Yes, you can clean. Not as complex as I originally thought.
1) Remove all of the silver screws
2) Separate the silver case (should split in 2)
3) Remove the 3 black screws in the middle
4) remove the center square cover that is over the lens
5) Use a duster spray to clean the lense and mirror
6) Reassemble in reverse order
Not knowing what I was going to get in, the entire process only took about 7-10 minutes.

How do I get in there safely to clean the mirror?? what do i unscrew first etc.. it still working just fine but the color is going after 15 years and i need to clean the inside.


Hello.
I would not recommend you to touch the mirror. It is hanged sort of reflection surface facing down so it is not real dust collector. You can clean lenses of your CRT tubes (red, green and blue) to improve your picture. Just remove rear cover taking out black and golden screws and you will see dusty lenses right away in the middle of the TV. Use DRY "Bounty" paper towels to remove dust from lenses, don't wet it with any solutions or it will leave film on optics. Just in circular motion move dust to the black plastic edges of lenses. Don't worry about some specs of dust that inevitable will be left behind - they will not affect image at all like thick layer of dust do.
Regards.
Russ.

We have a red and green light shining through the screen. You can only notice it when the background is white.


You may need to clean the projection lenses (all 3). They can usually be accessed by removing the rear cover and removing the light deflection plate (it just keeps light from leaking out of the TV into the area behind your TV). Dirty lenses scatter the light and cause dim, washed out images. Clean them with a soft dry cloth to remove the dust, but do not scrub. Once the free dust is removed, lightly moisten a soft cloth with dish water and continue cleaning the lenes. Dry and polish lightly with a soft cloth.

Recently I have noticed a small spot appearing in the same place on my pictures. It is not lense related as it occurs with each lense. It is also out of foccus, any ideas?


You have dust on the sensor which sits inside the camera body. It usually gets in and settles on the sensor when lenses are changed and the internals of the camera are exposed to the air.

You can try cleaning the sensor yourself, but it is advisable to have a professional do it if you haven't done it before or are not confident in doing it because it can result in even worse issues and more dust. You also need special dust cleaning tools and solutions for your camera.

Epson livingstation 45" tv


I just fixed the problem on my epson 57" living station. The picture is like new. Yo have to clean the dust off of the the 3 lcd lenses. (I'm not sure if thay are actually called lenses)
You can get to these by entering thru the front of the TV. Yes the front. You must remove the screen. There are A LOT of screws. This screen housing covers the entire front of the tv. and you have to remove the back panel and ALL the screws on the back of the tv to get it off. The only electronics that have to be disconnected are the Speakers and the front control panel. They both have snap connectors. After you remove the entire front panel which houses the screen and expose the inside mirror you will see more screws. You must remove those as well to remove the mirror housing. DO NOT REMOVE THE MIRROR FROM THE HOUSING. Note that there is a peg that is next to a screw in thre front of the mirror housing thst you must pull the plastic housing out in that area to release it.After you remove the mirror housing you will see the 3 LCD panels or lenses. YOU DO NOT HAVE TO REMOVE ANY ELECTRONICS OR SCREWS AT THIS POINT. Use a can of compessed air to spray the dust out of this area. I used a vacume to catch the dust as it flew out in the air. Try to hold the can as upright as possible.Keep hitting it with the air until no more dust comes out. Put the tv back together. As you open up the tv you will see dust everywhere. I took the oppurtunity to clean as much as I could. The Mirror though was clean an I was afraid to touch it.

I am a Construction Salesman yet fairly handy. I have no electricle experience. This took me 2 1/2 hrs. I spent the first 45 min. trying to get to the lcd panels from the back of the tv. Don't waste your time. You can't.

Emerson ewd2203 dvd/vcr combo


you're not telling much besides the fact that it doe'snt work. One thing to try offcourse is cleaning the lense inside, remove cover and gently brush dust off etc. If there's no dust build up, then I guess its just another emerson gone bad, NOT a rare occasion. Use the warranty if valid, otherwise consider if the repair cost is worth it, or if you rather getting another DVD player that you can count on. Good luck
