To fix your problem please follow the below given steps
Step1
Power on your computer and wait until there should be an image displaying on your LCD monitor. Look directly into the monitor from a distance of about 1 inch way. Cup your hands around your face to block out the light in the room and get a clearer view of the LCD screen. Check to see if there is a faint light visible in the screen, which will indicate that the cold cathode backlight has gone out, or no image at all, which will indicate a different problem.

Step 2 Check the manual that came with your desktopmag-glass_10x10.gif LCD monitor or navigate to the manufacturer's website and find the model of cold cathode bulb that the monitor uses as a backlight. Purchase a corresponding replacement bulb

Step3 Power off your computer and then remove the monitor cable from the port on the back of the computer case. Disconnect the monitor stand from the monitor either by pulling out the plastic latches or by removing the screws holding it to the monitor's casing.

Step4 Lay the monitor face down onto a stable work surface such as a desk or table. Take out the screws along the edges of the monitor's casing and set them aside. Lift the back side of the monitor case off of the monitor and set it aside. Check to see if your model of LCD monitor has the back light directly exposed on the lower end of the monitor or if it is hidden behind another plastic or metal piece.

Step5
Remove the screws holding the plastic or metal piece over the bulb if there is one present and set the piece aside. Check to see if your model of monitor keeps the bulb in a plastic casing or if it is soldered directly to the metal. Use a soldering tool to remove the solder or instead use a rotary cutting tool to cut into the clear plastic casing around the bulb if it is inside a case.

Step6
Slide the new bulb into the open spot on the monitor and either solder it in place or use a piece of tape to cover over the opening you made on the plastic casing with the rotary cutting tool. Place the metal or plastic cover back on if there was one and reattach the screws. Set the casing back onto the monitor and place the screws back in.

Step7 Put the stand back on the monitor and then reconnect it to your desktop computer. Power the computer on and wait for an image to appear on the screen to make sure the back light bulb was installed correctly.

Please rate me if this solution works for you

Thanks......Have a great time.

    how to open a ACER AL1713 monitor


    Hi - there are more hidden screws so you need to undo those:
    1. Where the stand joins on the back, there are two plastic bits either side of the pivot. They don't look as if they come off but if you squeeze them (squeeze top and bottom) then they unclip.
    2. Remove the 4 metal screws you have just revealed (2 each side)
    3. Remove the 4 larger metal screws holding the stand to the monitor
    4. Remove 1 metal screw that you have just revealed which was hidden by the metal plate on the stand holder.
    5. Use a straight-bladed screwdriver to create a gap at the bottom of the monitor between the silver front / black back of the case.
    6. Open this up all around, and remove the silver front - undo the multi-cable connector which connects to the operating buttons and put the silver part to one side
    7. Lever out the monitor chassis.
    8. Put the LCD face down on a table but make sure there is nothing underneath it (I have two black blobs where mine sat on a bump in the table!)
    9. Then open up the cage with the electronics in it, by undoing 2 screws and sliding the cage off.
    10. Remove the four screws holding on the power board (the big one with a mains connector, disconnect any connectors, and then remove the board.
    If your monitor is not working (even if the power light is dead), check for swollen electrolytic capacitors (tall things with an x at the top, made of metal with plastic around them). If you have swollen ones, that's probably why the monitor doesn't work. Replace them (make sure the + and - sides are in the correct places when you replace) and hopefully your monitor should work.

    If it still doesn't work, look for any heat damage and poor soldering.

    The backlight power supply in the H950 series suffers from a manufacturing defect. Hansol might replace the unit even if it's not covered by warranty anymore. Contact them.

    Otherwise (and if you have electronics skills), replace the electrolytic caps in the monitor's power supply. Take proper high voltage precautions!
    • Disconnect mains
    • Wait at least one day for caps to discharge a bit
    • Remove monitor stand (four screws)
    • Put the monitor face-down on the table, plugs facing to you
    • Remove back cover (snap-in, difficult to open without minor damage) - be cautious: front buttons are connected using a rather short cable, do NOT try to remove front cover
    • Remove EMV casing screws (four screws) and ground wire
    • Disconnect CCFL tubes (four connectors), noting connector orientation
    • Disconnect front buttons pcb
    • Lift EMV casing side facing to you
    • Disconnect power supply board (left) from signal board
    • Unscrew/remove power supply board - caution: C12 is likely to store mains voltage even after days!
    • Replace caps (C34 and C66 are likely failure candidates for IPHS19-S rev1.2 boards; you might also replace C31, C32, and C35 while you are at it) - higher voltage and temperature rating are okay, capacity has to match
    • Assemble everything again

    with a small flat head screwdriver, insert into the edge and pop open the small plastic

    pieces that surround where the stand connects to the monitor. put plastic pieces aside.

    lay monitor on soft flat surface front side DOWN. with a phillips head screwdriver,

    remove 4 screws in the center that hold on the stand. put stand and screws aside.

    lay monitor on soft flat surface front side UP. insert flat head screwdriver into the

    side edge of the grey plastic and turn screw driver so the plastic surrounding the

    screen edge pops up exposing an area surrounding the screen. put plastic rectangle

    piece aside.

    slide out plastic buttons piece from the side and put aside.

    with a phillips head screwdriver, remove 8 screws (4 on top and 4 on bottom) that hold

    the screen assembly to the back housing. now lift screen assembly out of the plastic

    housing. put back plastic housing and screws aside AND lay the monitor screen with the

    FRONT side down on a flat soft surface.

    with a phillips head screwdriver, remove 2 screws that hold on the metal electronics

    cover. slide the cover down and remove. put the cover and screws aside.

    USE CAUTION!!! Some components may still contain a charge.
