Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Samsung's LCD monitor SyncMaster 740N; backlight failed, I replaced bulging capacitors on PSU and burnt fuse but backlight is still not coming on


There is a inverter transformer on the board that may be defective that generates the high voltage that drives the lamp, you may end up having to replace the whole inverter board to get it working again.
