Acer AL2216W Capacitor Replacement

필요한 것

  1. Acer AL2216W Capacitor Replacement, Discharge the old capacitors: 1 단계, 이미지 1/1
    • CAUTION: If you are uncertain about handing high voltage parts, follow all provided warnings! A capacitor discharge tool is STRONGLY RECOMMENDED.

    • The filter capacitor will hold the most residual charge. Use caution around this capacitor!

    • Unplug the monitor for 24-48 hours. Wait 5-7 days before swapping the filter capacitor.

  2. Acer AL2216W Capacitor Replacement, Remove the stand: 2 단계, 이미지 1/2 Acer AL2216W Capacitor Replacement, Remove the stand: 2 단계, 이미지 2/2
    • This monitor never came with a hinge cap. If yours has one, unclup the marks in black.

    • Remove the 4 screws from the monitor stand with a Philips #1 screwdriver. Remove the bottom screws first.

  3. Acer AL2216W Capacitor Replacement, Remove the back of the monitor: 3 단계, 이미지 1/2 Acer AL2216W Capacitor Replacement, Remove the back of the monitor: 3 단계, 이미지 2/2
    • Sort this screw separately, as it is unique.

    • Remove 4 fine threaded screws from the back of the monitor with a Phillips #0 screwdriver. All of these screws are the same.

  4. Acer AL2216W Capacitor Replacement, Unlatch the clips (Bottom): 4 단계, 이미지 1/2 Acer AL2216W Capacitor Replacement, Unlatch the clips (Bottom): 4 단계, 이미지 2/2
    • If the monitor has never been serviced, a flathead screwdriver may help at the expensive of damaging the plastic.

    • On the bottom of the monitor, there are four slots to open the monitor. To release these clips, use a Jimmy or flathead screwdriver.

  5. Acer AL2216W Capacitor Replacement, Unlatch the clips (Side): 5 단계, 이미지 1/1
    • If you are having trouble doing this, use a pry tool. An unserviced monitor may not come up as easily.

    • With the monitor unclipped on the bottom, pull the sides of the monitor up. Do this slowly to avoid cracking the LCD.

  6. Acer AL2216W Capacitor Replacement, Remove the IEC socket screws: 6 단계, 이미지 1/1
    • After these screws are removed, the power supply will be exposed.

    • With the back of the monitor off, remove the 2 screws on the IEC power connector using a Phillips #0 screwdriver.

  7. Acer AL2216W Capacitor Replacement, Remove the video connection screws: 7 단계, 이미지 1/1
    • If you do not have a nut driver on hand, needlenoose plyers can be used.

    • Remove the 4 screw pins for the video cables from the monitor. Use a 5mm Nut bit/driver to remove the screw pins from the power supply shield.

  8. Acer AL2216W Capacitor Replacement, Disconnect the backlight cables: 8 단계, 이미지 1/2 Acer AL2216W Capacitor Replacement, Disconnect the backlight cables: 8 단계, 이미지 2/2
    • Disconnect the CCFL cables from the power supply board.

  9. Acer AL2216W Capacitor Replacement, Disconnect the button board: 9 단계, 이미지 1/2 Acer AL2216W Capacitor Replacement, Disconnect the button board: 9 단계, 이미지 2/2
    • Board removal is optional.

    • Disconnect the flat flex cable that goes to the control board.

  10. Acer AL2216W Capacitor Replacement, Remove the power supply shield (Part 1): 10 단계, 이미지 1/2 Acer AL2216W Capacitor Replacement, Remove the power supply shield (Part 1): 10 단계, 이미지 2/2
    • Remove the 2 lower screws that hold the power supply shield to the monitor with a Phillips #0 screwdriver.

  11. Acer AL2216W Capacitor Replacement, Remove the power supply shield (Part 2): 11 단계, 이미지 1/3 Acer AL2216W Capacitor Replacement, Remove the power supply shield (Part 2): 11 단계, 이미지 2/3 Acer AL2216W Capacitor Replacement, Remove the power supply shield (Part 2): 11 단계, 이미지 3/3
    • The lower shield does not have to be removed. However, it will make disassembly easier.

    • On the right side of the monitor, remove the remaining screws holding the shield in place.

    • Lift the lower plate up while removing the power supply shield to remove it from the monitor. Once this is done, you will have access to the power supply.

  12. Acer AL2216W Capacitor Replacement, Remove the power supply: 12 단계, 이미지 1/3 Acer AL2216W Capacitor Replacement, Remove the power supply: 12 단계, 이미지 2/3 Acer AL2216W Capacitor Replacement, Remove the power supply: 12 단계, 이미지 3/3
    • If you see bulged capacitors, assume there is residual charge. THE FILTER CAPACITOR MUST BE DISCHARGED! THE BLACK SCREW IS A GROUNDING SCREW AND MUST BE PLACED CORRECTLY.

    • This capacitor is only found on older power supplies. Replacement is advised, but not required.

    • With the power supply shield removed from the monitor, identify the power supply. Take note of the values, including the inverter cap (if present).

    • Remove the 4 screws from the power supply. Once this is done, lift up the power supply at a slight angle to clear the chassis. Do not lift too much or the connector may be damaged!

  13. Acer AL2216W Capacitor Replacement, (Optional) Capacitor polarity marking: 13 단계, 이미지 1/1
    • If the PCB is marked to avoid mis-installation, the flux will wash these marks off.

    • If you are unsure of the position of the capacitors, mark the polarity with a permanent marker. If the capacitors are incorrectly installed, they will explode when power is applied.

  14. Acer AL2216W Capacitor Replacement, Add flux to the capacitor leads: 14 단계, 이미지 1/1
    • If you do not have flux on hand, solder can be used. Some flux is difficult to clean if overused.

    • To prepare the board for capacitor replacement, add flux or solder.

  15. Acer AL2216W Capacitor Replacement, Remove the old capacitors: 15 단계, 이미지 1/3 Acer AL2216W Capacitor Replacement, Remove the old capacitors: 15 단계, 이미지 2/3 Acer AL2216W Capacitor Replacement, Remove the old capacitors: 15 단계, 이미지 3/3
    • Use of a Helping Hands is recommended to avoid soldering iron contact. If you do not have one, hold the board at an angle.

    • While a partial replacement may work, the remaining capacitors will fail. It is best to do them all while servicing the failed ones. Refer to this guide for a soldering "how to".

    • Move to a workspace with ventilation or use a fume extractor. Once in an appropriate workspace, desolder the old capacitors. Heat up each leg and remove it.

    • After removing the capacitors, clean up the old solder with a desoldering braid. Lift it with the iron when removing it.

  16. Acer AL2216W Capacitor Replacement, Installing brand new capacitors: 16 단계, 이미지 1/1
    • Check the capacitor polarity before soldering the new capacitors in. Incorrectly installed capacitors will explode with power applied!

    • Install the new capacitors. Check the polarity and bend the leads so they do not come loose during installation.

  17. Acer AL2216W Capacitor Replacement, Solder the new capacitors in: 17 단계, 이미지 1/3 Acer AL2216W Capacitor Replacement, Solder the new capacitors in: 17 단계, 이미지 2/3 Acer AL2216W Capacitor Replacement, Solder the new capacitors in: 17 단계, 이미지 3/3
    • Once the polarity is verified, solder the capacitors in. After installation, cut off any excess lead.

  18. Acer AL2216W Capacitor Replacement, Clean the flux off of the board: 18 단계, 이미지 1/1
    • After verifying there are no cold solder joints, clean the board. This can be cleaned with 91%+ Isopropyl or denatured alcohol.

  19. Acer AL2216W Capacitor Replacement, Test the monitor: 19 단계, 이미지 1/1
    • Put the monitor back together and test the repair.

I did not replace the large capacitor on the Acer monitor yet. All other caps have been replaced. I may have to replace the FSPO55- ZP102A as it has a hot spot beside it. I don't know if the part number is right? Do know where I can buy it. Tom B

These older CCFL panels usually burn on the PCB by the inverter coil and main transformer (the Delta branded part, in this case). The LED monitors limit the failure points to the transformer.

It sounds like your PCB got burned from the heat by the transformer or the inverter coil. This is very common and the boards are designed to take it. However, if you are concerned you should buy a new power supply board altogether if that makes you more comfortable.

In step 12, replacing the capacitors with ones with a different capacitance rating instead of using a capacitor rated for higher voltage makes no sense to me electrically. The capacitance rating is the important part, if you use a capacator rated for say 35 volts when the original is rated for 10 makes no difference whatsoever. the rating just means MAX voltage.
