    Well, thank you for your answer. I also think that it's about LCD screen or the flat cable. But, since screen displays images perfect when notebook connected to exrernal VGA monitor, most possible is LCD cable. Because, if screen was damaged, wouldn't it have to show the same images in flickers when connected to external monitor? Of course this is just what logic says. Cannot prove this.
    I know here is Sony section. Sorry for any confusion, but from your answers to the whole post, and being kind of desperate, I asked here.

    no because when you use double connection (vga+lcd) the laptop change resolution/ratio/frequency on lcd (in fact the image is centralized...),
    so is not the same state.... your lcd couldn't work in a particulary condition of resolution/ratio/frequency ..... idem for cable....

    or simply the cable is not right connected or needs a thickness

    This was my first thought and doing that is how I blown the fuse.
    But the fact now is that old screen works, after I bridge the fuse, every time I plug it while the new one always gave problems.
    My thought is that new screen is wrong either for my fault or because was sold faulty.

    Is it possible to damage a screen by plugging it to a back light blown fuse laptop?

    very improbable....

    instead is possible that the new screen in not 100% compatible.... I had same issue with a samsung N350

    I'm glad to hear that!

    Screen part number is ok, the guy at the store choose it after I sent back lable picture.
    Spare screen must be faulty. I talked with supplier and I have a new screen on the way.

    I hope this new one will work.

    Thanks a lot for your answers

    Edit. It works!!!
