Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Well my Acer AL1711 finally gave up in as much as the screen flashed briefly at switch-on then went blank, regardless of brilliance setting so I decided to take it apart and try to fix it. The good news is that IT WAS NOT THE LAMPS that I feared in my earlier post and was easier than I had ever dreamed! First allow a good period of time for the internal components to discharge before starting. Remove the plastic clip at the base hinge to expose 4 screws - remove all four to release the stand. Then remove the 4 black cross head screws that appear to hold the back on, they do but there is more to do. Carefully tease the silver surround away from the case, best to start in the centre of each side and finish at the corners. There are many plastic clips to release before the surround comes away. Now remove the four cross head screws holding the pushbutton switch circuit board. The whole assembly can now be removed from the case and reveal a metal cover held by 2 SHORT (remember that!) SHORT! threaded machine screws. These once removed will allow the case to be slid away from the holding tabs located down the edges of the cover and removed. Now unplug the connectors from the board that has the mains input connector attached to it. You will see a heatsink with 4 electrolytic caps above it. Silly ACER designers, have placed the capacitors so that they get all the heat from the heatsink! Yes folks, the capacitors are above the heatsink when the monitor is in its normal operating position! So all the convected heat dries them out, nice. So the fault is due to a silly design error! Replace all 4 capacitors, two of them are 1000uF at 16V and the other two are 470uF at 16V, all radial types. Try and get capacitors with the highest operating temperature, at least 105 degree types and remember these are polarised, make sure you connect the capacitor + wire to + on the circuit board. You should have no problems with re-assembly but don't put the wrong screw where the short ones went or you are liable to see it come out of the screen LOL! Most important - - Don't forget the screw holding the earth tag to chassis. Good Luck, you will be amazed how much brighter the screen is now!

There is just no way you will be happy to hear it needs service or replacement under warranty.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

check your power supply and power cable and check your monitor cable if its not damaged..or try your monitor to another computer..
