Powerbook G4 DVI: Monitor keeps going to sleep

When I boot the system the screen is black, The only way I can get the monitor to come on is to close the lid and put the computer to sleep.

sometimes i have to repeat the process of putting the computer to sleep and waking it several times before the monitor comes on.

is this a MOBO issue ? (i read someone mention an inverter card ) .

"You Need to restart your computer . Hold down the power button or press Restart""

After restart I got a dialog iofmring me there had been a problem with X and this was the problem :

I occasionally get a black screen on a TiBook 800, but under different circumstances. The latch sometimes doesn't catch, so when I close the lid, it pops open before the machine has finished going to sleep and gets in this unfortunate state. I think I once or twice cured this by reclosing the lid and reawakening, but forced power down is usually needed. PITA.
