Toshiba satellite S855 reboots to blank white screen. No POST activities. using external monitor do not display any thing. replacing the memory chip does not help either.

✔ Best Answer
So the toshiba screen and a working external monitor both show the white screen with nothing on it? Did anything happen to it or did you make any hardware changes just before this started?

If the external monitor had worked then likely the problem would have to do with the screen only, everything else being OK. But since neither do then the problem is going to be some difficult-to-isolate internal problem.

Thanks for your reply to my question.
I was so frustrated, so I started to take the laptop apart, in doing so I found the
Monitor cable is loose.
Reseat the cable, every thing works. Thanks God.
I asked my self a question, why the external monitor does not work?
I do not know. It is good to know for future troble shooting.
Thanks again. God bless you... merry Christmas...

I'm glad you fixed it. The external monitor not working threw me off too. By chance does the external monitor work now that you've reconnected the laptop screen?

Yes , the external monitor now works with a delay of a fraction of a second.
I will make some research to find out why the external monitor was performing the same way as the laptop monitor (white blank screen).
I will share it with you.
God bless you.
Thanks for your assistant.
