LCD monitor broken

[Guest]

Hi,
the lcd monitor of my toshiba satellite m70, is broken. But I think the problem concerns the light, because lcd crystals correctly works (I can see the desktop if I put a lamp towards the monitor). I've just changed lcd inverter, but with no results!
What may I do?

Your backlight is dead. It's integrated into the LCD these days. You'll have to replace the entire panel.
