If you see bulged capacitors, treat the power supply as if the capacitors are holding a residual charge.
In most cases, the filter capacitor is okay. It MUST be discharged if being replaced. In addition, the black screw (Blue marker) is a grounding screw and cannot be lost.
Only lift the power supply board at a slight angle. Lifting it any more then this could result in pin or video processing board damage.
If you cannot find the original capacitors, the original parts can be safely substituted.
This capacitor is only used on older power supply boards. If your board has this capacitor, it should be repalced. However, it can be left alone if it looks okay.
With the power supply shield removed from the monitor, identify the power supply. Along with the listed capacitors, take note of any others you want to replace (Ex: Inverter coil).
Remove the 4 screws from the power supply. Once this is done, lift up the power supply at a slight angle to clear the chassis mounting holes.
