Toshiba Phone System

Toshiba Satelite P205?

I am working on my friends computer and I am stumped. The computer will power up for all intensive purpose, power light shows on, and the cd-rom spins up, and I even get power to the USB ports. However I get nothing on the screen no post, now errors not even a flicker. So far I have tried using an external, using the FN+F5(display switch). Some random keys even cntrl+alt+del, FN+F3(hibernate), FN+F4(sleep), keyboard functions for the screen brightness and just about anything else that looked like it used a function key. I have also tried removing hardrive, and ram; and AC power w/o battery, and with battery. {Tried removing the battery, and holding the power down for 20sec(Toshiba Phone Support as far as they would go)}, 30sec, even 1min. I am trying to avoid the conclusion I keep getting in my head(dead system board), but I think I am out of options. Does anyone have any advice, or had same issue, and knows the resolution? If so please help. Thank you.

1. If you have pulled EVERYTHING that can be removed (Keyboard, Touchpad ribbon, battery, optical drive, RAM, wireless, modem, hard drive) and I do mean EVERYTHING that could possibly be causing a short that is removable... and it still won't power on, then it is a dead board. Now if you pull EVERYTHING, then you get a no RAM beep, put a single stick of RAM in... if it posts, you know that it is a short in one of the components you disconnected... because a bad keyboard can keep a laptop from posting. A bad optical drive can cause no post. You might want to disassemble the laptop and check for loose screws making connections inside. You might want to remove the heatsink/heatpipe combo and repaste it... essentially taking the laptop apart and rebuilding it. But it might just as easily be a bad mobo dude. end of line
2. I suggest rechecking the screen itself. I know its obvious but the only other thing is graphics card.
