| If your AL2216W is having problems, it is likely due to bad capacitors. Here are some common symptoms of bad capacitors: | | | ***''Note: While some issues may be corrected with a partial repair, this is NOT RECOMMENDED. One bad capacitor usually means the rest will fail!''*** | | | * Power issues (Present issue) | | * Excessive transformer/inverter hum (Present) | | * Backlight problems | | * Auto adjust problems (VGA) (Present) | | * Random power issues are only resolved through a full power cycle (unplugging the monitor) | | * Video issues (Ex: Unstable image, video instability) | | === Original capacitor values (For Delta 00A power supply) === | ***''NOTE: I based the capacitor list on my monitor's specific power supply (Delta 00A). UNLESS YOU HAVE THE SAME PART IN YOUR MONITOR, YOU MUST VERIFY WHAT YOURS NEEDS TO AVOID COMPATIBILITY ISSUES BY TAKING THE MONITOR APART TO IDENTIFY WHAT CAPACITORS ARE USED. However, in many cases, the stock part is likely NLA or hard to find a matching replacement for, especially as these monitors age. As such it is very likely, you will likely need to use different capacitors that either have a higher voltage or uF rating and swap all of the original capacitors that remain that match the old part, even if they work, as doing this will likely cause the remaining original capacitors to fail sooner.''*** | | ***''IMPORTANT: whenWhen swapping capacitors, stay as close to the original as you canpossible. It’s okay to install a 35v 1000uf35V 1000μF part in placeinstead of a 25v 1000uf25V 1000μF part (or a 25v 2000uf25V 2000μF replacement), but grossly exceeding the value of the stock part does not offer any benefits.''*** | | ***''Part availability caution: While I didhave done my best throughout this guide's life (and still do what I can) to keep up with part phaseouts (and replacing hard "obsolete in practice" partsvalue components) by mitigating thisthe issue as needed with components of a similar parts in voltage or uF rating, I cannot continuously monitor the market. You may need to make additional substitutions!''*** | | | * 25V 1000uF (x2) | | * 10V 1000uF (x1) | | * 25V 220uF (x2) | * 16V 2200uF (x1, ***''FoundOnly found on early power supplies, and is used to drive the inverter transformer.
