Camera beeps 3 times the shuts off

Well, have you ever considered that the lenses MIGHT be defected? If it's true, you can send it back to the manufacturer, as long as it wasn't YOU who made it defected.
Another tip, is maybe the lens isn't made for that type of camera.
Lastly, the lens can just be broken, so you should carefully examine it, and see INSIDE of it, to make sure all of the parts are their. Hope this helps (:

The three beeps mean that the lens motor is unable to extend the lens assembly.
This could be due to a low battery situation, but the most likely cause is the lens drive train stuck or jammed. You'll find generic instructions on solving some cases of jamming here.

Unfortunately, more serious cases (due to falls, shocks, and most of all, the camera being turned on while some resistance prevents the lens from extending: e.g., if the camera accidentally turns on while in a pocket) require the repair shop.

Everytime I try to turn it on, the lens comes out for about a second, the camera beeps 3 times, the lens retracts and the camera shuts off. The battery is completely charged and the camera is only 4 months old. HELPP :(

If the camera is older sometimes the battery brakes down after starting as the motor for the lens needs a lot of power as the starting of the lcd does. Had a similar problem with a different camera. I tried a friends battery and suddenly all worked fine.

sounds like a lens error, does the lens extend or retract? You probably have to get the lens back on track, use gentle pressure wiht the camera face down on a towel covered table and turn on to see if the camera tries to retract the lens. I really dislike these types of cameras that extend the lens everytime, if it turns on in your pocket, your doomed!

Same problem; however, after taking a hard look at the camera I noticed that the lens was tweaked; that is, is was not evenly extended so I pulled (by hand) on the inner, extended lens piece and viola; I turned it on, the lens retracted and extended upon application of power as usual.

My guess is the 3 beeps is much like a BIOS error with a PC...when there is a hardware problem they beep on startup...in this case, the camera was letting me know the lens was stuck.

HTH

Is it an actual beep, or is it a beeping noise coming from the lens? Does the lens extend? I ask this because this is the noise the lens focus gears make when they are knocked out of alignment, or debris gets in them and jams them.

Please eject camera battery and clean with a pin your battery tip in your camera with care fully.

Hope its helpful to you

OMG! so i read all these suggestions and nothing worked or i was just confused..tried the tapping thing but didnt work..so i finally just kept twisting the lens and pushing it in and out..it doesnt really move but i was angry and hoping this was doing something..i turn my camera back on a IT WORKIN AGAIN:) im so happy becuz i was so pissed that i had to buy another camera but i suggest trying this method if the table tapping dont work..OH and my lens didnt look crooked at all so if urs look straight and stilling doing stupid beep thing ,,,try this!

My guess is that your camera has been dropped recently and that the beeping is a result of the lens not extended when powered on. My Mother-in-Law has the same camera exhibiting the same symptoms. I've been able to get it to turn on by slightly pulling on the lens prior to turning it on. One of the plastic gears inside is probably damaged.
