MacBook black screen on boot, no chim
Hi, i have the following problem:
now when i startup the macbook (macbook dual core, 2007) i have the laptop which switches on, the light which firstly is flashing fastly and the is on and still, but i have no chim sound and the screen stays black and do not light up.
Previously it is happended that during the firware update process (after properly downloading it), accidentally i pressed the power switch and the process of updating stopped. So i deduce the firware never updated.
What can i do, as i cannot see if i am properly starting the mac in safe or in target disk modes, or from the original install disk on Dvd, becouse i do no see anything on the display?
Btw, i tried to connect the laptop to the tv, but no signal in output is received by tv.
I would buy a firewire cable and connect it to the iMac i have, but will i be able to startup in target disk mode even if the display is not working? And will i be able to restore in that way a firmware on the macbook?
Any idea or help ?
