Repairing the Acer AL2216W LCD monitor
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.
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.
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.
