Quickly go to the Acer website and check FAQ's and while there also find out how to get an RMA to return it. My guess is you have a bad monitor. At $200 roughly for a replacement I would hustle. I am assuming you got nothing but a white screen but did get video on your TV.

Hi...there,
It's seems you got a busted AD Board... your LCD bios had been damaged or erased.

Hi; I had the same problem. I know that sometimes devices require you to perform some type of '10-30 second' "hold" of one or some of its buttons in order to 'reset' the device, so to speak. So, having said that, try this:

1) Turn your monitor off (no green light) but leave it plugged in.
2) Leave it off for about 10 seconds.
3) Hold the [2] button on your monitor (the one to the immediate LEFT of your monitor's POWER button).
4) While holding the [2] button, now press and HOLD your POWER button.
5) Wait for your image to appear and STAY onscreen for about 5 seconds, then release both buttons.
6) Your monitor should retain its onscreen image.

Hope this helps! Good Day to all!

It may have blown fuse in the backlight inverter board, that will be the first place to look.
Post pictures if you can.
