| 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 NEEDSTHAT MY CAPACITOR LIST IS ACCURATE TO AVOID COMPATIBILITY ISSUES BY TAKING THEYOUR MONITOR APART TO IDENTIFY WHAT CAPACITORS ARE USED. However, in many cases, the stock part used is likely either NLA or hard to find a matching replacementdirect match for, especially as these monitors age. As such, you will likely need to use different capacitors that either have a higher voltage or uF rating and swap all of the remaining original capacitors that remain that matchwith the old component ratings for the newer part, even if as there is a chance they work, as doing this will likely cause the remaining original capacitors totake on more wear and fail much sooner.''*** | | | ***''IMPORTANT: When swapping capacitors, stay as close to the original as possible. It’s okay to install a 35V 1000μF part instead of a 25V 1000μF part (or a 25V 2000μF replacement), but grossly exceeding the value of the stock part does not offer any benefits.''*** | | | ***''Part availability caution: While I have 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" value components) by mitigating the issue as needed with components of a similar 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, ***''Only found on early power supplies, and is used to drive the inverter transformer. This was not used in later power supply revisions as it was removed at some point.''*** |
