Filmorepetty, The "switch-mode-power-supply" has gone into SHUTDOWN mode because it has detected a fault with itself or another circuit. Or it could have just blown a small fuse on the circuit board of the SMPS. Will the pilot lamp light-up? Did it have a clean, bright, crisp, image displayed on the lcd panel the day before? How old or how many total (approx) "ON" hours of use has it seen? Do you know that 98% of lcd monitors use "cold-cathode-fluorescent-lamps" and an accompanying "electronic ballast" circuit to generate the WHITE LIGHT needed for you to see the pretty colors on the LCD Panel?? Same basic lighting technology as the new screw-in socket curlie-Q CFL light bulbs! Only your monitor's lamps are thinner and straight and hung on the rear of the LCD panel. A failure of the ballast circuit could cause SMPS to shutdown. I suggest you visit some other websites for more info on what other owners are doing to try and repair BLACK SCREEN lcd monitor problems. The first place to go would be YOUTUBE and search and view the longer 6-12 minute video clips of "LCD monitor disassembly" and "LCD monitor repair" just FYI and to know what you are dealing with??? Your unit could also have FAILED electrolytic filter capacitors on the SMPS printed circuit board. I'm 12fixlouie Bye for now.

Screen is blank

Those models are made by BenQ. Their notariety is bad solder connections that cause the drive transistors to overheat. Sometimes it just blows fuse pf751(2 amp); other times it will damage a transistor or two (2sc5707 or 5706 x 4).
Be sure to resolder the output transformer leads.

Unexplained Blank screen.

Looks like your Power Supply has gone Kaput .. Usually it is the Electrolytic Capacitors on the Power Supply Board, try a new one, or replace ALL the Electros with same or better ones.
