    Re: Acer AL1916W LCD Monitor Power Problem

    Acer monitors are notorious for using several different power supplies.
    There is no way anyone can make suggestions without seeing yours.
    Please include some photos of top and bottom of all boards, using the managed attachments feature you will have to resize to a maximum of 2000x2000 pixels Try to get as clear and detailed photo as you can.
    Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

      I agree. Most likely a 700G(900G in this case) style PSU/Inverter board on the inside. Most of the time there are cap problems only.Follow Alexanna's suggestion (and PlainBill's instructions) and post pics of your boards.

      • Intel Core i5-7600K 3.8GHz
      • 16gb GSKILL TridentZ RGB DDR4-3200
      • 1 M2 SSD + 2 WD Blue 1TB (Mirrored)
      • Windows 10 Pro x64
      • GeForce GT1050
        2 x Acer KA240H + 1 Vewsonic VP2130 21 (a cap replacement job )

            U106 looks weird on pins 1 and 4, and there's a black blob above it.

              1) If you hookup a working computer to the Acer displaying your favourite wallpaper, can you see it if you shine a flashlight on the lcd?

              2) Check the voltage regulators on the logic board. They are U101 and U102.

              3) When you press the on/off button, what is the voltage on pin 4 on the connector between the power and logic board? Does it change when you presse the on/off button?

                Red herring. U106 contains the firmware. The mark the ICs with colored paint to identify what firmware is on them.

                For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

                Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

                  Hello,
                  I have the same power board and I am having a hard time getting the schematic for it, I was hoping that you would be kind enough to send the part number information that is stamped on top of IC802.

                  Thanks
