Did the lens get hot (closed in hot car)?- probably melted some of internal lubricant and /or adhesive on rubber rings or caused the rubber ring itself to start to deteriorate

Canon digital camera no power


Power issues are common in anything electronic, including digital cameras.
A digital camera can fail to power up for a number of reasons, but fortunately, they're often related to the batteries, making them minor in nature.
If your digital camera won't turn on, check several things to diagnose the problem.
Battery Life
It is common to try to turn on your digital camera, only to see that it will not power up. A highly likely cause of this issue is the power in the battery or batteries. If you've used the batteries for an extended period of time, mistakenly left the camera on or are using old batteries, they may simply be dead. Remove the batteries from your digital camera and test them in another electronic device, such as a remote control. If the second device won't turn on, the batteries may need to be replaced or recharged. b> Battery Position b> Though it sounds like a mistake that is too simple to make, it's easy to insert the batteries incorrectly into a digital camera, especially if it's new and you're unfamiliar with it. When the batteries are put in backward, the digital camera will not power up, leading you to assume there may be a graver problem. If the camera will not turn on, open the battery compartment and verify that they're in correctly. If not, rotate them appropriately, close the cover and try to power up the camera. b> Lens Track Problem b> Depending on the camera bag you use, the camera may occasionally and accidentally get turned on while it's in the bag. When this happens, the lens may begin to extend outward from the camera, but get blocked by the camera bag. All this can happen completely unbeknownst to you, which can lead to the camera not turning on the next time you need it. In some cases, the lens can get knocked off its track, which can result in your camera's power light illuminating once the camera is turned on, but the lens not emerging from the camera body. In more severe cases, the lens' repeated attempts to emerge while stuck in your camera bag can burn out the small motor that operates the lens. When this is the case, take your camera to a repair shop and have a technician look at, and fix, the problem. b> Defective b> Although not likely, there's always a chance that when you buy a new digital camera and load it with fresh batteries, it won't turn on. If this is the case, the camera may be defective in some way. Because new cameras are covered under warranty at many shops, take the camera back to the shop and explain the issue to a technician. Hope it helps.

The only way to clean the lens internally is by disassembling the camera. As this is difficult and easy to damage the camera if doing yourself or expensive if sending for repair, I would leave it unless it is causing bad problems with the picture. You could try putting the camera in a ziplock plastic bag before putting inside the case to keep dust out.

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.

You can also have a look at THIS link.

Hope the advise is useful. please do not hesitate to let me know if you need any further assistance. Also, please be so kind to let me know if you found this helpful.

Regards

If your camera went into "standby" mode, the lens retracted and you may have thought it was off. You put it into the bag and slight pressure on a button reactivated it and the lens tried to come out but may have been prevented by something in the bag. This causes a lens error. Try these: 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 Canon's, 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.

Turns on for a few seconds, lens starts to extend, turns off.


Assuming that the battery is OK, the most likely cause for this behaviour is an out-of-kilter lens drive. If you are lucky it's just some dirt or grit jamming the lens. Try blowing some compressed air in the lens grooves, or place the camera with unextended lens down and gently tap it to dislodge any dust or sand. Repeat while lens is extending. If this fails, GENTLY try to help the lens extend. Do not force (you risk permanent damage to the lens, assuming there is no damage now). If the lens rotates while extending, still gently try to help it to rotate, twisting in the direction of rotation.

Unfortunately, it's possible that the lens drive is actually damaged and can't be realigned manually. In this case the camera will need to be repaired. Also, even if you succeed in refitting the lens - you'll hear a slight "click" and the lens will start working happily - you'll need to exercise extra care in case the drive is no longer up to spec.

Unfortunately, "extending lens" cameras are very sensitive to accidents such as turning on while something is blocking the lens from extending fully. In most cases there's an overload sensor which will retract the lens and power off the camera - but sometimes the overload will have damaged the internal drive train, which is often (not very cleverly, in my opinion) made of plastic instead of metal.

What you're experiencing is called a lens error. Lens errors are fairly common. 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 ...

Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:

Lens error


This error... lens error.. can be the result of many abuses. If the lens is held back as it is extending, it can damage the tiny parts. If the lens is bumped while it is extended, it may damage the internal parts beyond repair. Sometimes the lens get off track as a result of a blow while extended.
If the camera is dropped, the lens mechanism can be damaged from the impact, even though it is not extended.
If you treat a digital camera with a lot of care, and put in a padded camera bag, you may extend the life of the camera.
