Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 SAMSUNG 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.

Samsung sync master 740N no display. Flickered started then the display goes after its been on for a short wile. Could this be a problem with the capacitors?


Yes, look for two 1000uf capacitors on the power supply PCB near the output cable to the main PCB. They will have swelling and discolouration. Replace those and should fix your problem.

For best pictures, you need to set your PC video resolution to the native resolution of this monitor, which is 1280x1024 @60Hz. Try that first before opening up the monitor to look for bad components.

It sounds like the CCFLs (backlight lamps) in the monitor are failing. You might be able to get them replaced by the manufacturer if it's still within warranty. Otherwise the fix might involve an expensive technician and replacement parts.

This may be part of the OSD (on-screen display). If you don't have your manual you can download it here: http://tinyurl.com/yzerbd I would check the manual.
