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:

WELL,

May be it was out of a fluke or something, or i hit the right point.

from the link someone gave http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html, there are 7 Steps :

I followed and as the Camera was anyways out of warranty and nothing worst can happen than break the lense, I press firmly couple of times on the lense while pressing on/off button repeatedly, at one point, it clicked and started working.

Lens won't retract


You will need to send it back in to the manufacturer to fix. If you are not too late you might get it for free or a cost of about $20.

Otherwise sometimes they might replace it with a refurbished one (which is fine) for a cost of about $50 or so.

I have a hp photosmart r742 digital camera,when i try to take picture it says lens error r740-033. What should I do?


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.

Regards
Andrea

Lens error


If the lens makes griding sound when trying to extend, the lens probably does not extend or retract because of debris or a misaligned gear box. The lens can in about 50% of the cases be repaired without having to replace it. Try to return to manufacturer first. If you're out of warranty, there are third party place that fix them such as camera lens repairs. If you want to do it yourself, there are also free camera repair guide websites that show you how to replace the lens, the replacement part is usually available on ebay.
