Question about Samsung SyncMaster 740N 17" LCD Monitor
Remove all the mounting screws, stand first, then using thin flat blade screw driver to separate the front from the back starting at the bottom edge and work your way around, be careful on the cable attached to the front bezel. Also look at YOUTUBE on how to open most LCD monitor cases.
Here are the service manuals: http://elektrotanya.com/?q=showresult&megnev=samsung&megnev2=740n&kategoria=&kat2=all
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
Post back what you see inside so we can guide you further and it will help out other people in the future also.
