Blank screen boot fail Toshiba Satellite M55-S329

[vovocika]

Hi, I have a Toshiba Satellite M55-S329. As I tried to boot it up in the morning, the screen lighted up in a blank whitish mode and stayed this way.
Took out the battery, booted back, same blank screen.
Keyboard is responsive, I tried CTRL-ALT-DEL and it rebooted but right away back in the same blank screen.
I tried to cold boot pressing the power key 30 seconds, with no effect, gets back into the blank screen.
I put in the Recovery DVD, it begun reading it upon boot, but was stuck into the same blank screen.

My first guess and hope was this is some sort of stand-by Win-XP problem.
Now my guess is that this is a hardware problem, either a disconnected video card, or perhaps system board failure. Do you have any suggestions? ...

Try attaching an external monitor. If you see the same blank screen, your motherboard has probably gone belly up. I hope not though

thanks Tmagic.
I tried attaching a monitor, same result, so I guess indeed it's the motherboard. I sent it back, it's still under waranty, and I'll post here the resolve after it'll be done.
