| 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 This will not impact the monitor electrically, as long as the upgraded part is balanced (Example: 25V capacitor is obsolete, but a 35V part with the same uF rating is available or voltage matches, but replacement is 100uF better) and all of them are replaced at the same time.'' NOTE: I have not tried partial replacements with upgrades, so I do not know keeping the originals and upgraded capacitors will work. It's always best practice to avoid this anyway as a set — keeping one 25Vthe rest will fail and replacing a bad 25V with a 35V may not workwill likely need to be upgraded too.''[br] | While I have done my best throughout this guide's life to counter this problem by pickingwith nearly identical shelf stable substitutes for monitors with olderif the original is “obsolete in practice” values, these may require upgrading as wellwill also become obsolete and will need to be further upgraded.''*** | | | * 25V 1000uF (x2) | | * 10V 1000uF (x1) | | * 25V 220uF (x2) | * 16V 2200uF inverter (x1/Early)
** ***Inverter coil capacitor. This will not be present on most power supplies. Not found on later as it was removed in newer revisions.)*** |
