I repair monitors
Based on other models , it sounds like you are having a powerboard-inverter issue.
It just so happens that I hjust got one in that's doing that, I should know in a day or two (maybe sooner) what the whole story on this model is.
Good timing !!??

Looks like you have a burned lamp.
Most LCDs have a lamp that lights the screen's image.
If you see the image, but its too dark.....you need a lamp replacement.
Please rate this answer if its useful

When laptop on booting immediately press del.
And the screen will run normally.
But if the screen is still white, force to press power button soon.
And it will shutting down.
After shutting down, repeat this action.
It will work.

This model AL2017 20" Acer monitor is known for having a bad power inverter board. The capacitors go bad, which causes the backlight to completely stop working or flicker intermittently. If you feel like you are electronically and mechanically inclined the board is easily replaced. Search ebay for AL2017Power Board -- its about 15 bucks plus shipping. If you are super inclined to do so, you can replace the bad capacitors on the board yourself. Look for the capacitors with the bulging tops. I replaced the 220uf and 1000uf caps on the right side of the board. My monitor now works great and it only took an hour or so and 2 dollars worth of capacitors.
