Repairing the Acer AL2216W LCD monitor

Filed under: Acer, Monitor Repair, Viewsonic 

This time we will be doing a power supply repair on the Acer AL2216w 22″ flat panel LCD monitor. This monitor uses the DAC-19M010 power supply board,  this board is also used in the Viewsonic VX2235WM monitor and Westinghouse LCM-22W2 and a few LCM-22W3 units.

To do the repair you will need the following tools: Soldering iron, de-solder braid, Phillips screwdriver, small flat blade screwdriver and a 3/16″ nut driver. You will also need the following electronic parts: qty(2) 220uf 25v capacitor, qty(2) 1000uf 25v capacitor, qty(1) 470uf 25v, qty(1) 2200uf 10v and qty(1) 1000uf 10v. For information about getting the correct capacitors for the repair check out this article about capacitors. We sell a repair kit with all of the parts for $14.00


This is not guaranteed to solve all problems but in most cases this is the issue with this model.

If you don’t want to do the repair yourself, use the service request link above. Most monitor repairs run $30-35 plus return shipping.

Here is the monitor we will be repairing, this unit has no power but the power board can also cause a flashing or flickering display or a monitor that is slow to display a picture.

First remove the power and signal cables and the stand. Now lay the monitor on a flat surface and remove the 5 screws shown circled.

Remove the back cover by inserting a flat bladed screwdriver between the two halves and gently prying the case apart. There are plastic latches every 2-3 inches around the perimeter.

With the back cover removed the next thing to do is remove the shielding. First remove the 4 3/16″ nuts on the VGA and DVI connectors. Next we need to remove the small screws that hold the shield in place as well as the two screws that hold the power plug.

This picture shows the backlight plugs. These will need to be unplugged. When plugging them back in the order is not important.

With the shield removed you can see the power supply board and the video board. To remove the board just unscrew the 4 screws shown circled and separate the two board at the interconnect.

Here is a closeup picture of the power supply board. It is model DAC-19M010. The parts to replace are shown circled in red. The location numbers and values are as follows:
470uf 25v C204
220uf 25v CE101 and CE108
1000uf 25v CE104 and CE103
1000uf 10v CE105
2200uf 10v CE106
Unsolder the old capacitors using the soldering iron and wick and solder in the new ones. Be sure to insert the new ones with the polarity stripe going the same way as the old ones.

After replacing the 7 capacitors just reassemble the unit and test. You should now have a fully working monitor.

  2. Hey I have this power supply board in my Westinghouse LCM-22w3 and I attempted to repair it based on the article for my monitor on your site. I didn’t have the correct values for the capacitors needed but the one that was visually not good was the 2200uf so I replaced it with a 35v 1000uf that I had laying around. The odd thing is that it powered up and ran perfectly for about an hour and then stopped.

    Prior to this the monitor would power on and show “no signal” but would not display any picture, the power LED would also come on. Now nothing comes on, not even the LED. I can hear the transformer making it’s high pitched noise (I think that’s the transformer).

    Again I have tried to repair it when I found out radio shack had the correct capacities although all in 35v. So all of the capacitors have been replaced based on the power supply board DAC-19M010 diagram here on your site with the exception of the 2200uf, this one I had to solder 2 1000uf in parallel. I have also checked the 3 fuses on the back of the board and they all check out.

    At this point I would like to know if there are any other typical failures to look for and if my first attempt at a quick fix with the single 1000uf capacitor ended up causing damage to other parts. If you could point me in the right direction to do some preliminary testing to see if it is the power supply or the monitor itself and if it is the monitor, what I should check. Thanks for the help!

  4. Hello Chris,

    The capacitors from Radio Shack will not work in the high speed switching power supplies that are found in monitors and computers. You need to only use low ESR, High ripple current and high temp parts. It sounds like the new caps you put in have failed under the stress of the circuit. We have an article posted on our site about choosing the correct caps for the job, it is at: http://www.ccl-la.com/blog/index.php/capacitors/ Checkit out and try the repair with good quality caps and you should be back running again.

  6. Apparently there are more than one version of this Delta power board. I fixed my VX2235wm using this general information. My power board has 2 half inch square IC’s located approximately where the DELTA name appears on the picture and a blown 220 uf capacitor approximately located where the red mark is on the DAC number. On the right hand side , reading from the bottom, the second capacitor up is replaced by a small plastic transistor and 2 capacitors. Now you have, reading from the bottom, a 330uf cap, a small transistor, a 220uf cap, and I believe a 1000uf cap. The 330 and the 1000 were lime green in colour and marked as a subsiduary of Nichicon and looked fine so were not replaced. All of the other caps (CapsXon) were replaced with Panasonic capacitors. Unfortunately, the 2 1000uf 25v caps (the 2 side by side) were of a much larger height and would not allow the EMI cover to be installed. I cut a horizontal slot in the cover and the caps stick out about 1/8 ” but everything else works fine.

  10. Just wanted to say thanks a whole bunch, this repair guide saved me a ton of money by repairing my burnt out monitor as opposed to buying a new one. On a side note while I have the same model of monitor (AL2216W) the power supply board inside was different (DAC-19M009); the capacitors and location numbers were slightly different but applying a little bit of common sense made everything turn out fine, still worked with the same $14 repair kit I bought from you guys. Thanks again.

  12. Thank you, my wife is happy now that her monitor is fixed :) It was kind of a pain to get the factory solder off but it worked.

  14. I have the AL2216W with the DAC-19M009 board. Is this board interchangeable with the DAC-19M010? Tried replacing the capacitors already, no luck. Easier just to replace the board I think, but the DAC-19M009 is about twice the price of the DAC-19M010.

  16. Both boards should be compatible. Where you get into problems is when you have one board with sound and one without but neither of these have sound.

Tell me what you're thinking...
