I have a Toshiba Satellite P205D-S7438 17" laptop. When I turn it on, I get horizontal white lines from the top of the screen to about 1/4 of the way down and the remaining 3/4 of the screen is black and blank. I read that the symptoms may be either a bad LCD Inverter or the backlight. I replaced the inverter as many said it was the easiest to do for troubleshooting... It didn't fix the problem. Now could it be that the backlight bulb is bad or is there something else "internal" that I haven't seen or read about that could be the problem??? I connected the laptop to an "external" monitor and it works. I can view the desktop and do whatever I want. I welcome all thoughts and opinions! Thank you!!!
If connecting it to an external monitor worked without issue, I'd venture to guess that it is an issue with the LCD itself. Your best bet is to try to find a decently priced LCD that will work with it and go from there.
