Hi, I have a Toshiba Satellite A300, 5 years old. Today the screen began flickering. The upper 5-10 cm are ok, but the rest shows flickering white horizontal lines.
It happens from the boot. No problem with an external monitor.
Thanks to an irisvista guide, I managed to dismount the screen, but how may I know if the problem is the inverter, the LCD cable or anything else?

Thanks!
