Having problems with your Emprex LM2201 22" LCD Monitor ?
EVERY TIME THE LM2201 MONITOR IS PLUGGED INTO THE ELECTRICAL SOCKET, IT MAKES A HUMMING NOISE?
Ruth_coleman, Only a guess but I would say that the "switch-mode-power-supply" or "backlight inverter power supply" has a problem. Is screen always BLACK? how old is unit? How many "ON" hours on this unit? Is unit new? Out of warranty? Did it ever display a PERFECT IMAGE on it? When? Did it always HUMM?? FYI check out VIDEO clips of LCD monitor disassembly and repair on YOUTUBE to find out what is inside a typical LCD display. You will have a better handle on what to do about getting it repaired or to trade in for new. Yes, monitors can be REFURBISHED with new SMPS/Inverter boards for $50-$100.

Dead Monitor Hi, I bought my parents an HP computer for Christmas and now, only 7 months later, the monitor stopped working. w1907 monitor. I've read some comments on here but don't understand what the solutions are saying. I don't know anything about inverters etc. Can a monitor be fixed or replaced since it's only 7 months old? I think that's an extremely short lifespan for a monitor, especially since it's used only a few times a week for short times. Thank you the monitor is dead
