I have a problem with my l2046nv monitor. It turns on, flashes and stay dark, you can however see the picture but it's VERY faint (flash light helps). I turned it off and on.. it would turn on and show a picture, but then a second later just go black... the green power button is on and green. I keep turning it on and off..... I do it about 20 times and ... it stays on but it’s still so annoying to do this. Is there a way to fix this problem? Thank you for any help you can provide!

Look for bad caps with leaking/bulging tops or seals first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
