Introduction |
| If your AL2216W is having problems, it is likely a capacitor fault. Here are some signs 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 issue) | | * Backlight problems | | * Auto adjust problems (VGA) (Present issue) | | * Random power issues that only resolve if the monitor is unplugged | | * Video issues (Ex: Unstable image, video instability) | | === Original capacitor values (Delta 00A power supply) === | | ***''NOTE: Most referenced values are obsolete, or PSU specific - validate which ones you need before purchasing parts. AS THIS GUIDE (AND MONITOR) HAS AGED, MANY OF THE ORIGINAL CAPACITORS BECAME OBSOLETE AND WILL NEED TO BE UPGRADED GRADUALLY, AS OLD VALUES BECOME HARD TO FIND. This will not impact the monitor electrically, as long as the upgraded part is balanced (Example: 25V capacitor is obsolete, but a 35V part with the same uF rating is available or voltage matches, but replacement is 100uF better) and upgraded as a set — keeping one 25V and replacing a bad 25V with a 35V may not work.[br] | | While I have done my best to counter this problem by picking shelf stable substitutes for monitors with older “obsolete in practice” values, these may require upgrading as well.''*** | | | * 25V 1000uF (x2) | | * 10V 1000uF (x1) | | * 25V 220uF (x2) | | * 16V 2200uF inverter (x1/Early power supplies. Not found on later revisions.) |
