It sounds like your T-Con board went out again. You might re-seat your ribbon cables just in case you didn;t get them in good from the last repair. If that doesn't help I would say that your T-con board went out again.

Yes and No. Read this article on how to do it: http://www.popphoto.com/gear/2011/07/how-to-scan-negatives-using-standard-scanner-0

I found the home website for your camera on sony.com's european website:

I didn't see anything about a negative picture on screen when filming, though.

Good luck on finding a solution to your problem.

Yes yes it is persistent problem and it gets worse.

Try demagitizing the moniter. In the monitor's menu it will have a picture of a magnic , select it. Sometimes it is listed as degrous. After selecting this, your screen will seem to spin then settle. If your still have problems, a magnic may have come close to the moniter while it was being stored, and that will ruin the picture.

In the Twain driver for your intellscan, there should be a selection for the type of scan. It should be set to "black & White Negative" or "Color Negative". The program you use to edit the scanned file should be able to change it to a positive if the scanned result is still negative. Programs such as Photoshop, Paint shop Pro etc can use Twain to have the scanner scan directly into them. There the phot (negative) can be edited and saved.

The pictures are indeed negative.  When scanning negatives or transparencies make sure you have the scanner set to the appropriate setting, otherwise simply Invert the colors in Photoshop, or similar photo editing software.

The manual didn't show negative and slide support. I recommend you some of the hp products like HP Photosmart C7180 All-in-One, HP Scanjet G3010, HP Scanjet G4010, etc.
