Answers :

I had similar problem. Sometimes the screen goes white while working under windows and repositioning the display, but most of the time it goes white during power up. I decided to check the display cabling by removing the speaker/power-button panel and display coverings. Although I couldn't find a loose cable, the display was consistently working properly. I put it back together and so far so good.
\015\012To expose the wiring:
\015\0121. Power off, unplug power cord, and remove battery.
\015\0122. Open display all the way flat with the keyboard.
\015\0123. The speaker/power-button panel is also the cover for the display hinges. You can pry the panel off by prying up the hinge covers from the sides facing center.
\015\0124. The inside display covering is fasten with four screws in the corners covered by the rubber bumpers.
\015\0125. The outer display shell is attached by 6 screws. 2 on each hinge and 1 on either side of the LCD unit.
\015\0126. The mic and camera cables can be unpluged by gentle prying the plugs out.
My Acer Extensa 5420 "craputer" does this too. I shut it off, remove the battery, wait a few minutes, then put it back together. When I turn it on, wah-la , it works. My other matching "craputer" gotten taken to the shop where the genius had it for over a month... never again.
