I think I have killed by trying fuse

@rudi50090 your images are to small and definitely not clear. It makes it very difficult to zoom in to evaluate those components. Post a couple of good ones and focus on the area around the display adapter connector. Straight up and down with no artistic expressions work best :-)

Anyhow, there are a few fuses for your display. Check those for continuity with your meter (once we have better pictures, we can point them out). Since you have your board out, you may have to reinstall it at a later point so you can measure the voltages.

The schematic maybe hard to see. Save it to your computer and open with your graphics viewer.
