If anyone is interested in the Service Manuals that are included with the user manual for many Sony Cameras.
There is a website:
http://www.user-service-manuals.com
The website contains hundreds and hundreds of service manuals for all types of electronic equipment. His collection of Sony manuals is extensive.
It is purely a charitable website. The man has over ten years experience in electronics repairs. However he lives in an Eastern European country with a ditctatorial regime.
To acquire a manual, he asks only that you make a small donation of $15.00 to The Association for Human Rights Defense International.
There is a link that takes you directly to the charitable site, and after you've made your donation you may copy and paste the link to the manual you wish to have, email it to him and he sends you a download link for a PDF file within a few days. I was able to get a service manual for the TRV730, TRV830. It is very clear and enlarges supurbly.
The only difference is that it says TRV725E, but it is exactly the same, except that it is a European version. The manuals are in English.
All that he asks is to make a small donation to The Association for Human Rights Defense International (HRD), or work as a volunteer in this organization.
"HRD is international Charitable organization for defense of human and the civil rights in the world, especially in the countries released from communist and dictatorial regimes, first of all, in the countries of East Europe, ex-USSR (former Soviet Union), Russia, Ukraine and Belarus."
I was hesitant at first, but he came through with a maual worth it's weight in gold. All the expoded views of the camera are in the manual, and the part numbers and names. The manual is 279 pages so it is very comprehensive for those that are mechanically inclined.
Hope this was a helpful suggestion.
