So i have short circuited the C8 capacitor. I had the very same pattern on the screen that before : http://i55.tinypic.com/2a77tys.jpg

As i press the reset button, the screen goes black and as i released it is right away (1/15 sec) back to the same pattern. It is so fast that i don't think that anything reset.

What next ? :)
