Question about Westinghouse L2046NV Monitor
When the computer powers on the screen immediatly goes black within 3 sec of showing the screen.I tried a different monitor and it works fine. So it is not a cord issue. It is a screen issue. What could be the problem?
Look for bad caps (bulging/leaking tops) in the power supply first, it may have taken out the fuse and transistors in the inverter circuits also.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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.
