This capacitor is only used on older power supply boards. If your board has this capacitor, replacement is recommended, but not required unless there is obvious bulging or leakage.
With the power supply shield removed from the monitor, identify the power supply. Along with the capacitors previously mentioned, take note of any additional capacitors that were not mentioned (Ex: inverter coil).
Remove the 4 screws from the power supply. Once this is done, lift the power supply up at a slight angle to clear the mounting holes on the monitor chassis for removal.
