It may have dying power supply due to bad DC filter caps just like the HP as shown in my albums.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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: 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.

Hp l1906 LCD MONITOR SCREEN WONT DISPLAY. power lcd green light keep blinking. Any solution? thx


It is possible that the video card in cpu is bad, try hooking up another monitor to the cpu (computer) if you have one that will let you know if it is the monitor or the computer video card, Could be as simple as the driver is missing.

HP L1906 lcd monitors won't display anything


Yes you got badcaps!!! www.badcaps.net examples of what they are and what they can do and this is one of them. U/You can change out these caps and see if it fires back up again.

Even bulging caps are still issues I just fixed a emac with bulging caps as the emac would freeze not when i put in the new caps the ****** is doing great!!!! I would suggest you do the same.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620
