You need to verify whether it is your video source (ie: computer) or the actual monitor. To do so, put the monitor on another computer or try another monitor on your computer. That is the easiest to tell which one it is. If your monitor works on another computer, it's your computer, if not it's your computer and vice-versa.

Hyundai X91D power light flashing green with no picture

Try it on another PC alos check the VGA cable first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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:

Power on Green Light Blinks but no picture. Will not turn on. Hyundai Image Quest L705

bwpvemail, The units "switch-mode-power-supply" may be in shutdown mode. A tech will need to evaluate. Check to see if Hyundai has a refurbished swapout+cash program?? It's that or trade in for new wide screen, so the tech in the store "back-room" can possibly put $8 in new filter capacitors in your unit and with a little luck will have a 17" L70s for 1-2 more years use. 12fixlouie

My hyundai monitor

There's a certain combination of keys you must press to restore your monitor to its factory settings (the original settings of the monitor ). The most common way is to press the up and down button together (normally beside the function/ menu button). Another way to lighten/brighten up the display is to raise the brightness settings of the monitor or by changing the contrast settings. This method enables you to customize the display of the monitor to suit your needs. If you still have the manual of the monitor, you can find instructions on how to change the settings of your monitor.
