Hi i have a powerbook g4 model a1001. Because of a drop, has a broken hinge and some of the cabes coming from lcd(the copper ones). When i boot it i hear the chime, but i have no video signal, even tough i see a brief blink on the display. I tried to connect it trough dvi and svcd ports but still no output. I did the pranm & Nvram reset, but no effect.
