Introduction
If your monitor is acting up in some strange way, 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, replace the caps that have bulged to start to see if the power supply board sustained permanent damage due to bad capacitors. If none bulged and it acts up, replace them all, or use a ESR meter or even a multimeter with a uF check mode to see what failed. [ … ] 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. [ … ] caps. Not too shabby. 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 :-). I only labeled it "difficult" due to the fact you have to handle a bare power supply.
