Please help with lens assembly in a Sony DSC-H1 camera

Hello,


I have a Sony DSC-H1 digital camera that had a small piece of debris in the motor transmission unit that was preventing it from zooming in all the way.

I took it apart and fixed the problem, but now I do not remember the orientation of the lenses. I have tried putting it together 3 different times and each time it says "Turn power off and then back on again".

Please, can anyone provide a diagram or advice on getting it back together?

Gentlemen, I had the lens assembly properly assembled. There was a rotary optical pulse generator inside the transmission that I had missed. Once I put it on the shaft it worked fine. It seemed as if it were a sensor issue. Now I have another problem.
There is a voice coil motor that operates a focusing lens similar to that of a CDrom.

I took it apart for cleaning and did not observe the polarity of the magnets in it.

The magnets each have a red stripe on one corner.

Can anyone help me with this??

Please see the pictures below:

The focusing assembly with magnet cover on:



The back of the assembly with two sensors of some kind:



Here is the assembly without the copper cover, showing the metal backing plates for the magnets:



Here is a picture of the red stripe. I apologize for the quality, this is the reason I need the DSC-H1!

You should have gone to the technician when you had a problem.Lens assemblies are very complex and only Sony can help you.

I tried calling Sony about it. The only way they could help me was to charge me $3.75 or so a minute to talk to a technician. Since I do not own a credit card or haver a bank account, that is out of the question.

So i went to CR4, the engineers forum and a great place, and together with a gentleman out of the UK we reverse engineered the electromagnetic lens focusing mechanism. I was able, with his help, to determine the proper magnetic orientation for intersection of magnetic lines of flux thru the coils in the voice coil motor. In the end it was very simple.

I put it together and it works great. There is dust on the internal lenses that occasionally it will focus on, but I have taken over 600 great quality photographs with the camera so far.

I am glad I stuck with it, because I can now take the lens assembly apart in my sleep. I mean completely apart tot he individual component level. It is basically a series of very simple mechanism that have to be orientated properly to be assembled correctly.

The biggest problem, as I said, was the rotary optical pulse generator rotor coming off of the shaft and causing an error no matter what I did. I put it back on and now I have a great functioning camera I paid $35 for.

Here are some pictures I have taken of the mountains:















(I love macros and this camera does them very well. Those holes are about 1/16" in diameter.)
