Introduction
If your Acer monitor is acting up in some strange way,up, you probably have a case of bad or failing capacitors. Here are some signs of bad capacitors [ … ] * Power issues * No power * Video issues(stability, doesn't stay on when plugged into a computer, resolution, random image dropping, etc.) * auto adjustment issues * Power light flickers slightly * Random problems * it has to be unplugged from the wall frequently * Transformer hum* * Inverter hum* [ … ] *If you have inverter or transformer hum,any of these problems, replace all the caps that have bulged to start to see ifno matter the power supply board sustained permanent damage due tocondition of the other caps. I found 2 that didn't look bad capacitors. If none bulged and it acts up, replace them all, or useblew from the bottom causing this problem where the top didn't bulge, but the bottom did. You'll kill these problems right away if you do a ESR meter or even a multimeterfull recap with a uF check mode to see what failed.the following issues. [ … ] This one is having automatic adjustment issues, power issues when hooked up to a computer and transformer hum problems. I already took this apart to check the capacitors, so it will be easier then one that was never opened before. '''Expect a lot of trouble if you have never opened your AL2216W before. I am saying this from firsthand experience working on this monitor.''' I also know what capacitors failed in advance, so I was able to get them ahead of time. [ … ] I got this monitor free because of this, and after a full recap, I got a new monitor for 13.00 in caps. This was also my first recap I did on something I wanted to recover, and went in with zero experience doing capacitor recaps correctly-I screwed up ALL ATTEMPTS at practice before fixing this monitor. If you're afraid to try this, it isn't bad. This was the first time I did it and I didn't ruin the monitor and managed a successful repair. The only way you're gonna learn how to repair on the component level is if you take risks :-).risks. I only labeled it "difficult" due to the fact you have to handle a bare power supply. As of late, I have been having trouble finding the original capacitors I originally used to repair this monitor when I attempted to build a proper part list. As a result of this, I doubled the value of the capacitors further in the Parts section then I originally did when I fixed this monitor 7 months ago. I also did this because I feel Acer skimped on the capacitor ratings from the factory. [ … ] '''If you injure yourself performing this repair, I will not be taking responsibility for your actions! You have been warned to follow ALL safety instructions provided to avoid injury if unexperienced with high voltage equipment!'''
