Green light comes on but the screen and sound do not come on.

ViewSonic LCD (VA1912w) Went Blank

I am using this great LCD for about an year. But few times in the past my LCD didnt show up the display though the Green light was still ON, turning off the LCD and opening it again always solved the problem. But now My LCD completely went blank. Turning off/on didnt work at all now. I've tried couple of other tweaks mentioned on this site but they didnt work. I am just seeing a blank screen with green light ON. and ya theres a very low hissing sound coming from the LCD.

There is a small IC in the power supply section,
not the IC regulator that's the problem.

Could be the lamp is failing.

I Had The Same Problem I Let My Xbox Cool Down For A Day And Then Turned It On And It Seemed To Work Fine

The alarm is just a coincidence i suspect, green light comes on and stays on probably not the battery at fault. It would be red.
If the green light goes out and screens just flash one of your screens are at fault or a loose ribbon connection.

this is most likely the sustainer board(s) problem. Replacing the sustainer boards should correct this problem for you. you can get the parts at vancebaldwin.com
