Is it possible to repair sealed-unit double glazing?

I have a large sealed double-glazed window in my conservatory and it has somehow become damp between the two panes of glass. This means that there is now condensation on the internal faces of the window, which I cannot reach to remove.

Shot of replacing the entire window (a lengthy and expensive operation) is there any way I can get rid of this condensation? I have tried warming the window and that does evaporate the condensation - but it re-forms as soon as the window cools.

    It can be removed and resealed. Unfortunately it will also seal in the moisture. Best bet is to have a new one made from a local glass shop. The cost for making a new one will probably not be significantly more than having them repair the existing one. I worked in a glass shop for about a year, we guaranteed our workmanship. If it happened again we would repair it or replace it for free. It will be easier for them to make a new one. If you had a shop install the exsisting one, call them to see if they will fix it as well as their policy on their work.

    No, once the gas inside is gone the only cure is to replace the glass, not the whole window. I've got a bunch here that need doing too.
