Hi
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

SOURCE: My Acer LCD Monitor AL1707A goes blank after 2 seconds

Try this,
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.

Screen flashes on then goes dark


Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

Monitor goes Black off and on .....


I had the same problem for about a week and solved it yesterday by downloading the latest driver by NVDIA who makes my video card (NVDIA GeForce 6200).
I had previously updated the latest Sony driver for the monitor. It did not solve the problem but could be part of the solution in conjunction with the new video card driver.

LCD Monitor Goes Black during Use


I had the problem sometimes, but then I connected a second computer to the analog input and found out, that the screen didnt turn black but switches between the inputs on an on.

I found out that the "input" button seems to be short or damaged, as the behaviour was invertable by pressing the button. I blew into the button some times (a very naive solution, yeah) but it worked, the switching stoppped.
