Dell U2713HMt - No Image but vertical moving lines
I've got a Dell U2713HMt. After i returned from a break to the monitor it only shows a blue image with vertical lines. The lines ar changing every time i've move the mouse or open the start menue.

You can find a Video (not from me) which shows the error: here
I've already opened the monitor and looked on every board. All capacitors are fine. Also no black or burned areas are visible. All conectors are pluged.
Has anybody an idea where i can find the error?
Edit: Here are the pictures from the built in diagnostics:
The question is also available in the german forum: here
Is this a good question?
