Camera will not come on but green light flashes and camera makes three beeping sounds. Already changed batteries and still same thing when powered on. What could be causing this problem?


The reason why your Samsung Digimax S500 camera beeps 3 times and shuts down is because the internal workings of the telescoping / retracting lens barrels may be damaged beyond reasonable repair, of the casual user, and the internal circuitry senses the malfunction.

And to open up and attempt to service any digital camera, with an electronic flash, is a dangerous proposition. The Samsung Digimax S500, for example, has an internal 320 Volt, 110 microfarad photo-flash capacitor that, if accidentally touched, would hit you like a stun gun. In fact, I had to discharge the capacitor by bridging two soldered contacts (just to the upper-left and upper-right of the "53", of the "STS2-53-SR" printed on the internal circuit board). And, even though I was careful to use an old, worn out flat-head screwdriver, electrically grounded (MUST have an insulated wooden or plastic handle), the discharge arc was so violent that it destroyed the tip of the screwdriver.

And don't think that the telescoping / retracting lens barrel can be "gently forced" open or closed, as the tiny DC motor has a plastic worm-gear on its shaft, initiating torque to a miniature train of 7 plastic spur gears, before reaching the final plastic spur gear track, 120 degrees part-way around the large outside lens barrel. So, to make a long story short, any attempt to manually move the lens barrel out, or in, will most certainly damage the spur gears, as absolutely no manual movement is possible at the worm gear on the motor shaft. And, anyway, the geared motor drive provides more than enough torque, by itself, to extend / retract the lens barrel, unless there is grit and debris interfering with the smooth motion of the gears and angled slots.

Sand, grit, and other debris can sometimes find its way between both lens barrels, and into the curved, 120 degree spur gear track. And since the 120 degree spur gear track is not lubricated, it can possibly be cleaned by very lightly tapping the camera on a table top, with the lens down (this is assuming that both lens barrels are fully retracted) , to loosen any debris, and then using a vacuum cleaner: Taking care to apply the open nozzle of the vacuum cleaner, tilted (to reduce its intensity), but directly on the perimeter of both lens barrels, so as not to **** the lens barrels out, yet apply a strong vacuum into the narrow grooves.

This may damage your camera -but do you really have a choice?

Also, a piece of paper can easily inserted between the lens barrels and run along the circumference to help clean out some of the grit. And repeat the process above, until the lens works.

But that's assuming that the problem is caused by dirt and grit in the inner workings of the lens.

The other cause for the telescoping / retracting lens barrel to malfunction is either the camera was dropped (while the lens barrels were extended), or the camera "POWER" button was somehow depressed while the camera was stowed away, and the lens barrel was prevented from extending. Either situations will break off 2 teeth of the final circular plastic spur gear, that powers the 120 degree spur gear track on the outer lens barrel. If you know either of these to be the case, then your camera cannot be fixed, and a repair would probably cost more than the camera.

Manual Aperture Video For Canon Eos Rebel 500D T1i


Unfortunately the Canon T1i shoots video in full automatic mode. This means that if you want to change the depth of field...well, you can't. There are many angry T1i owners trying to get Canon to release a firmware update to have it perform like the T2i, but so far that has been fruitless.

So what can a budding videographer do get some artsy-looking footage with his or her T1i? The Band-Aid solution involves fooling the camera into thinking there is a manual lens attached so that the camera will relinquish control. To do this, the communication between the camera and lens has to be severed (don't worry - it doesn't involve modifying anything).

Step 1.
Put the camera into Av or Manual mode.

Step 2.
Select the desired aperture (if the aperture is "wide open" - e.g. F1.8 on the 50mm F1.8 II lens, then skip Step 3).

Step 3.
Press the depth of field preview button on the side of the camera (above the T1i or 500D logo on the curved part of the camera body).

Step 4.
With the DOF preview button still depressed, push the button as if to remove the lens, and turn it very slightly until "F00" shows up on the back display. You may now release the buttons.

Step 5.
Switch the camera to video mode. There will be a warning message, but just do as it says and shoot anyway.

You're now ready shoot some nice shallow DOF shots. Use the manual focus ring on your lens to shift the shallow depth of field around in your shot. Please note that since the camera is no longer communicating with the lens, autofocus will not be available to you. Put the lens in manual mode on the barrel to be safe - many lenses do NOT have manual override and forcing the focus ring while in AF mode can damage the lens.
Good luck and happy film-making!

Lens error on vivitar x327 , lens wont go in


Hello
You especially might consider this if the lens barrel appears obviously damaged, bent, or crooked such as from a fall. Try forcing the lens. More people have reported success with this method than with any of the other methods. HOWEVER, there's obviously some potential for damaging your camera by using this method. Variations include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Attempt to straighten or align the barrel if it's crooked or twisted. Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). While doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.
hope it helps, if not take camera to the technician, if so

Fixing a Lens Error on a Digital Camera


This has to be THE most common failure mode for a digital camera. Some common error messages that might show up on the LCD's of cameras with this problem include "E18 lens error", or "lens error, restart camera". Some cameras might show nothing at all, but merely make a beeping noise as the lens goes out, then in, then the camera shuts off. Sometimes the lens won't even move.

The problem is actually quite common throughout all camera brands. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended. Believe it or not, one BIG contributor to lens errors is using a camera case. Sand, gunk, case fibers, etc... accumulate at the bottom of the case. These materials love to cling to the camera by electrostatic build-up from the camera rubbing against the side of the case (especially those cases with soft fibrous intreriors). Once these materials work their way into the lens mechanism, that's all she wrote. I have many cameras, and NEVER use a case for this very reason.

A camera owner that suffers this problem may have no recourse for having the camera repaired. Many camera makers will not honor repairing this problem under warranty as they claim it is due to impact damage to the camera, or sand or debris getting into the lens gearing mechanism (neither of which is covered under warranty). The quoted repair cost is usually close to or more than what the camera is actually worth.

Fortunately, about half the cameras that suffer this failure can easily be fixed by one of the following methods. None of these methods involve opening the camera, although some have potential to cause other damage to the camera if excessively done. If the camera is still under warranty, before trying any of these, please please first contact your camera's maker to see if they'll cover the repair, or to determine how much they'll charge for the repair. Who knows, you might get lucky. But if they quote you a number that's higher than the value of your camera, you may want to consider the following methods.

The methods are listed in the order of risk of damaging your camera. Thus make sure you try them in the listed order. And remember, these fixes (especially #6 and 7) should only be considered for a camera that's out of warranty, who's cost of repair would be excessive, and would otherwise be considered for disposal if unrepaired:

Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.

Fix #2: Remove the batteries, then remove the memory card. Then install new batteries, and turn on the camera. If you get an Error E30, it means you don't have a memory card installed, so turn it off, slip in the memory card and turn it on one last time.

Fix #3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particals that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.

Fix #4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.

Fix #5: Blow compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens. Other variations include blowing with a hair dryer in "no heat" setting, or sucking the gaps with a vacuum (careful with this one).

Now we're entering into the realm of potentially damaging your camera in conducting the fix. There is definitely some risk here, so take care when conducting the following two fixes.

Fix #6: Repeatedly tap the padded/rubber usb cover on a hard surface with the intent of dislodging any particles that may be jamming the lens. Other variations include hitting a side of the camera against the palm of your hand. A lot of people have reported success with this method. HOWEVER, there is also some potential for damaging or dislodging internal components with this method, such as unseating ribbon cables, or cracking LCD screens.

Fix #7: Try forcing the lens. More people have reported success with this method than with any of the other methods. HOWEVER, there's obviously some potential for damaging your camera by using this method. Variations include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Attempt to gently straighten or align the barrel if it's crooked or twisted. Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). While doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.

E45 ERROR SEE OWNERS MANUAL


Hello

The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful. please do not hesitate to let me know if you need any further assistance.

Canon PowerShot SD870 IS camera - Lens Does Not Fully Retract


Canon SD870 IS. Lense Error. Would not retract on power-down. Lense error reported when retracting zoom.

Noticed the rectangular frame about the lens was rotated off center. Manually rotated (squared-up) the lens rectangle while repeatedly powering the camera on and off. Modulating the power allowed for easier rotation of the rectangular lens frame.

Once the lens frame was square with the body of the camera, the lens completely retracted on power-down, and also zoomed in/out without error.

For some reason my camera keeps comming up with a "REMOVE LENS CAP AND PRESS > BUTTON" error but the lens cap isn't on the camera :(


it sounds like the lens barrel is out out alignment. Possible the barrel was stuck while it was extended. There is a sensor on the lens barrel asemmbly that must be in the correct position after the camera is turned off. If this doesn't happen then you will get this message..at least this is what I have experienced in my repairs on this camera
