My NEC LCD screen 1760 has a problem: on first starting the computer (or upon plugging in the D-Sub cable) it will display the computer's video output fine (Regardless if the computer is in dos, or windows or in bios setup, it gets displayed perfectly) However, it does so only for a second or two and then goes blank. I've tried resetting it to no avail. Since it does display perfectly well (when it does) I figure it can't be anything major wrong with it. I just figure I'd ask before I start to replace fuses, capacitors and such... Any help will be much appreciated

Hi:
Your monitor has a problem on its inverter board. It is an electronic component failure, and often it cost's more to fix it than to buy a new LCD monitor .

Power supply or backlight inverter problems, those are the two areas you need to check.
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, 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.
