Question about Westinghouse L2046NV Monitor
Check the caps in the power supply first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Hi you can inspect that what's wrong with your monitors. After you turned it on and the
screen went black, you have to check that if you can see the image on the
screen or not by shining a flashlight into the screen, not directly but find
the best angle to the screen and take a look very closely. If you can see the
icons or any image, there will be a minor problem. This is because of the lamps
inside screen. Some of them were broken and it is very easy to replace. If you
cannot see anything on the screen, there'll be some problems with inverter
board. If you have soldering tool and want to fix it by
yourself, check the caps first. It may cause this problem. Some caps might show
leaking or burn spot on the board because of too high temp. If you don't have
soldering tool, you better go get a technician to do so. Hope this help!! If
anything I can help you with, feel free to let me know.

My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is
1. the red light comes on
2.after about 1 second the green light turns on for about 12 seconds
3. the the green light turns off for about 1 second
4. then the green light turns on again for about 12 seconds
and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.
