On your power board you will have a faulty surface mount fet with 8 legs that controls the backlights.
There are 4 of these, but if any of them fail the protection circuit turns them all off.
Best best is to get it to a local technician for repair. It is not an easy task unless you have the right equipment.
Hope that helps. =)

Possibly either the backlight lamp or its associated power supply has failed.
Power buttons (mostly LEDs) have constant availability of low voltage (for some other circuits too) otherwise they wouldn't 'wake up' on command from a computer as some do.
The blackout could also be due to a failed main power supply so the incoming video is no longer being processed.

I have the same problem. I leave the computer on for awhile to warm up the screen. I don't know why, that seems to help. I turn off the screen on the bottom right and do that a couple of times. Behind the screen I unplug and plug and unplug and plug the screen in again. After it gets going, it works all day. But at night I like to turn off the computer to rest. So I have to do this every morning.

Yes, The inverter is the problem on your monitor. We have a step by step guide to dis-assemble and repair your monitor posted on our web site at:
www.ccl-la.com/monitor_repair.htm Your model is the same as the westinghouse L1875NW. We have a parts kit for $12.00 if you need it, it can be purchased on the guide page. If you don't want to do the repair yourself we can do it for $35 + shipping. This is a common problem with that series of monitors but the repair will get you back going.
I hope this helps, if so please rate our solution.
