The lens is stuck out

Lens may jammed or control board is bad. You may need to take it to a dealer or time to buy a new one.

Try pushing the delete, LCD power, and menu buttons while turning it on.

some cameras you can just push the lens in.

Was your camera working before you put the new battery? if yes, then its possible some dirt or grit has got stuck between the lens and the body and therefore you motor might be warming up.

Since you 've bought a new battery, I dont think It may not be the battery, the way you are explaining. It could be the lens motor itself, since its warming up.

Try to do the following: ( I 've got this checklist from the forum itself)

Remove the batteries from the camera, wait a few minutes. Put a fully charged batteries back in and turn the camera on. if it doesnot work then,

2: Remove the batteries again, as also remove the memory card. Then install the newly charged batteries, when you turn it on it should come back to life.
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 start up. This extra power can be useful to overcome any grit or sand particles that may be jamming the lens.
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.
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
6: Repeatedly tap the padded/rubber usb cover 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.

Try the above and let me if its any help.
Best of luck

TIPS:

Is the Lens stuck out?
More detail please.

My camera stopped working during a wedding. The lens is stuch out, it will power on, but right after turning on, it beeps 3 times, then turns off.
Hope we find a solution!

I had sent my camera in for the same issue and they did nothing to help with it. Seems to happen when battery gets low or dies, lack of on-screen battery meter doesn't help. Typically have to manually twist the lens to close it or open it after fresh batteries installed and then seem to fix it.

This blog post outlines repair procedures for stuck lens covers. An A400 is used as an example. But it should be similar for the A430:
