A lot of these camera's seem to come down with a '''"NO VIDEO" error''' in the upper left corner of the preview window. This is due to the failure of one or more capacitors on one of the video module's interface boards. Probably due to a combination of rather high temperature inside, and many years of use.
It is hard to determine exactly which capacitor is involved. But knowing that any one of the others might fail next, it is better to replace the lot while you're in there ...
The soldering is not for the faint hearted, and requires much more than entry level experience !! You may want to prepare everything, and seek help for the final soldering step ...
* Edit 7 jan 2016 : due to quite a few requests, I have assembled a few sets with the necessary capacitors that I can send by mail. Just ask !
* Edit 16 april 2017 : due to quite a few requests, a gain in experience, and several equipment upgrades, I have decided to offer a repair service. Just ask !
The "NO VIDEO"-error in the upper left corner seems to be common in these camera's.
6 capacitors in the video module will be replaced.
But take care : extremely fine soldering is involved !
