I have evenly spaced, rows of two vertical green and red lines from top to bottom of my vizio plasma P50HDTV10A


Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines. I turned the tv off and on but the problem persisted. Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.

Explaining Camera Focus


Camera: Focus We've seen that a real image is formed by light moving through a convex lens. The nature of this real image varies depending on how the light travels through the lens. This light path depends on two major factors:
  • The angle of the light beam's entry into the lens
  • The structure of the lens
The angle of light entry changes when you move the object closer or farther away from the lens. You can see this in the diagram below. The light beams from the pencil point enter the lens at a sharper angle when the pencil is closer to the lens and a more obtuse angle when the pencil is farther away. But overall, the lens only bends the light beam to a certain total degree, no matter how it enters. Consequently, light beams that enter at a sharper angle will exit at a more obtuse angle, and vice versa. The total "bending angle" at any particular point on the lens remains constant. camera-diagram3.gif
As you can see, light beams from a closer point converge farther away from the lens than light beams from a point that's farther away. In other words, the real image of a closer object forms farther away from the lens than the real image from a more distant object. You can observe this phenomenon with a simple experiment. Light a candle in the dark, and hold a magnifying glass between it and the wall. You will see an upside down image of the candle on the wall. If the real image of the candle does not fall directly on the wall, it will appear somewhat blurry. The light beams from a particular point don't quite converge at this point. To focus the image, move the magnifying glass closer or farther away from the candle. camera-diagram2.gif
This is what you're doing when you turn the lens of a camera to focus it -- you're moving it closer or farther away from the film surface. As you move the lens, you can line up the focused real image of an object so it falls directly on the film surface. You now know that at any one point, a lens bends light beams to a certain total degree, no matter the light beam's angle of entry. This total "bending angle" is determined by the structure of the lens.

My Cannon Power shot SX120 is less than a year old, I havent dropped or otherwise abused it. One moment the camera was fine, the next moment it has really bad horizontal lines in the pictures. The closer...


Have you tried to reset to original settings in the setup window. I would try that maybe..
If that doesn't work then its probably an issue with your sensor unit which is apart of your lens.

Doesnt seem to work with the lens which was on my old K1000 which is a SMC Pentax-M1:2 50mm, serial number 5918334 any ideas?


Although your lens is an older manually operated K mount and will physically fit onto your camera, there are incompatibilities which limit the level to which it is compatible with your *ist DS.

Ignoring the really obvious difference that your lens is totally incapable of autofocus, the first real incompatibility is that your camera body has one of the "crippled" versions of the KAF (autofocus) mount. This means that it lacks the mechanical stop-down coupler/indicator used on the original K mount. The result is that your camera body does not sense which aperture the lens is set to and will not stop the lens down to the selected aperture when you press the shutter release. The full specification KAF mount maintains these old mechanical legacy couplings, but as most owners don't use older lenses any more the crippled KAF isn't an issue to most users and significantly reduces manufacturing costs. Crippled KAF lenses can still use some manual K lenses, but only the ones which have the A setting on the aperture ring and your lens pre-dates this development.

Your only realistic fixes for this are to either replace the camera body with a model supporting the full KAF mount (expensive) or to use later K lenses with the description SMC Pentax A instead of earlier SMC Pentax M. You'll still lack autofocus but as long as the lens aperture ring is set to the A position then it will work when the body is set to shutter priority and Automatic modes. There are far more Pentax A lenses remaining in good condition than Pentax M so you should have no trouble finding them, but because of their compatibility with later mounts you'll find that prices are somewhat higher.

Note that there is no adaptor which will allow you to improve compatibility between your present camera and the lens you have asked about.

I hope that I've answered your question, if so please take a moment to rate my reply. If not, perhaps you should add a comment to further explain in which way your camera doesn't work with your lens and I'll then try to assist you further.

Were can you buy film .


Original Polaroid film ceased production a few years ago and so remaining stocks are all so long out of date that the built-in camera batteries are either totally dead or have just enough power to eject the cover slide before failing. There are suppliers of old stock film on sites like eBay, but unless you have modified your camera to take an external 6v dc power supply then you'll be wasting your money. Some suppliers claim the film has been kept fresh via refrigerated storage, but this only extends the life of the photo chemicals: cold storage kills batteries even more quickly.

There is one company, The Impossible Project, which has recently started to produce film for your camera with the approval of Polaroid. Their product only has eight shots per pack instead of the original ten, and currently it's only available in black and white but colour film is planned for production in the near future.

I hope that I've helped, if so please take a moment to rate my answer.

Hitachi 50SBX78B Horizontal lines and bow


John, Hitachi site is down at the moment, if you remove the clips on the front of the IC`s you will see the numbers of the convergence ic`s, and yes they are a pain to get out, they are probably stk 392-110`s if they are the originals, you`ll have to un-solder 36 pins total to get them out, check for burnt resistors in the general area of the ic`s and replace any that are burnt before turning the set on,be sure to order a tube of "heat sink compound" to apply to the back of the new IC`s, once on the set will probably still look poor, this is normal, run the set for minimum of 15 minutes then push the " magic focus button " inside the front door panel, after it has finished running magic focus it should look great, video-tek

Can changing settings delete the memory card?


It's no problem at all to get them back. Please see this post for several free software that you can download. You'll need to use a card reader with these programs though:

Finepix S5100


This sounds like a similiar problem I had. I brought it into my camera store and a young clerk put my settings back to the original factory settings in moments and it works beautifully again.
