I have a Sony Cyber shot DSC-H2. When the shutter button is depressed halfway, it does not focus as it should do. Is there a simple solution to this?

hi
if you are feeling a little DIY, then its not a terribly difficult problem, to fix but if you have stupid hands or are not confident in your abilties then rather let the pro's handle it.
step 1 Download the service manual, just google it, :D
Basically you need to replace part number 1-479-699-11 its the whole assembly that contains the little bubble switch mentioned above , its not very difficult to do but be very VERY careful of the capacitator for the flash, it will shock you and its not fun, and can damage the camera, in the service manual you can find step by step instructions on how to discharge it, but even if you have a little doubt, let a PRO do it!

i "repaired" the bubble switch by manipulating the blue ribbon harness where it goes into the black plastic housing on the front of the unit.
it normally curves out and down into the lower assembly, but i pushed the curve inwards and created an artificial bubble which now allows the AF to function correctly.
i don't know how long it will last but until i get the money to buy the whole assembly it will satisfy my needs. hi if you are feeling a little DIY, then its not a terribly difficult problem, to fix but if you have stupid hands or are not confident in your abilties then rather let the pro's handle it. step 1 Download the service manual, just google it, :D Basically you need to replace part number 1-479-699-11 its the whole assembly that contains the little bubble switch mentioned above , its not very difficult to do but be very VERY careful of the capacitator for the flash, it will shock you and its not fun, and can damage the camera, in the service manual you can find step by step instructions on how to discharge it, but even if you have a little doubt, let a PRO do it! i "repaired" the bubble switch by manipulating the blue ribbon harness where it goes into the black plastic housing on the front of the unit. it normally curves out and down into the lower assembly, but i pushed the curve inwards and created an artificial bubble which now allows the AF to function correctly. i don't know how long it will last but until i get the money to buy the whole assembly it will satisfy my needs.
