| [title] Identify the power supply | |
| - | [* icon_caution] ***If any of the capacitors have bulged, assume there is a residual charge remaining. Handle the power supply by the sides and do not touch the capacitor leads, and use extreme caution.*** |
| - | [* black] With the power supply shield removed from the monitor, identify the power supply. Take a note of the original capacitors and bring this list to an electronics store or buy the caps you need online. |
| - | [* icon_reminder] ***If you cannot find the original capacitors or they cost too much and a higher capacity equivalent is available for less, you can substitute the originals for ones with a higher rating, as long as they fit the board.*** |
| - | [* icon_note] The capacitor marked in red is only on older power supply boards. If you have a newer board, it is very unlikely to have this capacitor in place. If you have it, you will need to replace it as well. |
| - | [* icon_note] You only likely need to change the following capacitors: 2x 25V 1000uF, 1x 10V 1000uF, 2x 25V 220uF. If any additional capacitors are bad or you wish to change all of the small caps, take note of the other caps you may wish to replace. Replacement of the filter capacitor should be limited to cases where it has to be changed only, due to the cost. |
| + | [* icon_caution] ***If any of the capacitors have bulged, assume they have residual charge. Furthermore, handle the power supply from the sides and avoid contact with the capacitors.*** |
| + | [* icon_caution] ***In most cases, the filter capacitor on the primary side of the power supply does not need to be replaced. This capacitor should only be replaced IF it is bulging and you have a discharge tool on hand.*** |
| + | [* icon_caution] ***Original capacitor ratings (primary): 25V 1000uF (X2), 10V 1000uF (X1), 25V 220uF (X2)*** |
| + | [* icon_reminder] ***If you cannot find the original capacitors easily (or they are more expensive), it is okay to use capacitors with a higher uF and voltage rating. As long as they fit, you should not have any issues.*** |
| + | [* icon_note] The capacitor marked in red is only on older power supply boards. Never revisions of the power supply used in this monitor no longer use this cap. Replacement is recommended if you have it, but is generally okay to ignore unless it looks like it is bulging or has leaking electrolytes. |
| + | [* black] With the power supply shield removed from the monitor, identify the power supply. Write down which capacitors you need so you know what to get if you are buying them locally. |
