INITIALIZE SONY DSC-H2 - Sony Cyber-shot DSC-H2 Digital Camera

SOURCE: pre-shooting with sony dsc H2

There's a chance that the settings might have been changed.....Just try after resetting the camera to default factory settings.

SOURCE: sony's broken button issue

You need to use you fingernail and pop off the entire button assembly. When you have done this you will be looking inside your camera.

Set the new button assembly into the slots. It will not want to go on by just pushing down. The plasitc assembly is very slick so put a small piece of scotch tape the yellow stuff. I put the tape around the plastic assembly. Make sure you are only putting tape on the chrome plastic assembly. The reason for the tape is to get a good hold of the plastic asembly.

Once you have the tape on the assembly/chrome piece you need to really push down and twist clockwise. You will hear a click and then another click. Make sure you hear two clicks. I had to push and twist pretty hard to make it lock into place.

I had the same problem.
In another post on this site I read that a stuck lens or bad batteries can cause this. My batteries were OK and it seemed as if the motor or lens gear was stuck.
The shutter could still be opened and closed by pushing power while the lens cap button was either pressed or released.
As I could not move the lens and some soft "shocks" did not release it, I once again disassembled the whole camera. (5th time the last two days...)

Note that for my camera there seems to be some protection mode being activated after a few unsuccessful tries to power up the camera with the lens cap removed.
After this protection was active it was not possible anymore to even display anything until disassembling the camera and pulling some of those internal plugs.

After having removed the lens with moter (without the circuit boardss attached) I used an external DC laboratory power supply set to 2V DC (and with current limitation activated) to directly power the lens motor at its two soldering points at the backside.
First it did not work at all, but maybe because of bad contacts.
But then I managed to let the lens move in and out by reversing polarity of the 2V.
After a few times the lens seemed to move much smoother.
With the lens still out I carefully re-assembled the camera again.
Now everything works fine again.

If you do not have a DC power supply you might be able to put the two batteries in series and apply that voltage to the motor.
Do not use a larger DC voltage than retrieved by those two batteries... or you might damage the motor or lens or...
I am not responsible if you damage your camera...

Be careful with the cables and note that a part of most of the small connectors can be carefully lifted upwards at the end to release the cables !

Maybe this helps to reactivate more of those stuck cameras.
Good luck !

I have this problem too. The bad news is that so far, I have tried all the prescribed remedies. I called Sony. Hector had me press the preview button to see if I could get the camera to show pictures on file. It did. Hector then told me to press the preview button again, to see if it would switch to camera. It did not. I also set the camera to ISO and got a message to turn off the camera and turn it back on which did not work. All of this said, Hector determined that the problem was in the lens mechanism, and I could mail the camera to Laredo TX or find a dealer local that can fix it. Laredo will const me 149.00 American Pesos. I have yet to determine how to remove the lens my self, as it may just need cleaned out. If I find out how, I will post it here.

Sorry.
