Contax T2 repair guide on the net?

I have a Contax T2 camera and a couple of problems.

Somehow during last summer there had condensed water inside the flash and during

taking the next picture with the flash activated, the water "burned" on the

flash protection glas, the flash in it self is clean and ok.

I?m not using the flash that offen, but when used that little black dot is

visible in the photos as darkening the lower part or side of the photo.

Anyway it's a P'n'S camera that's beeing used when not wanting to take a

slr/dslr/mf along, so the flash is sometime needed, especially in evening/night

photography.

Also a problem is that the finder front palstic/glas screen is loose from the

glue and the prism is also loose. Is it possible to just glue these back by my

self or is it necesseray to somehow calibrate these at a camera repair shop?

I have been looking for a repair manual/guide showing how to de-assemble the

camera in order to try to clean the glas from inside.

Please, somebody help me, since it IS an extremely nice and well built quality

camera and I don't want to part with it.<div></div>
