hardware problem with powerbook g4 dvi - no video

[alcolix]

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.

If the cables coming from the display are cut then you won't be getting video to the display. As for the laptop itself have you tried booting it up to Target Disk mode and connecting it to another Mac to see if the motherboard and the hard drive work?

if i get the chime sound at the boot up, isnt suppoesed that all the parts are ok?
even if the cables from the display are cut, why doesnt work trough dvi or svcd connection? is it possible that the video card has a problem? if so why i get the chime at start up?
i tried the Hard disk on my pc and was recognized...
