Now after the screws are removed you will need to use the flat blade screwdriver to separate the 2 case halves. Insert the screwdriver between the plastic case halves and gently pry the 2 apart. The case has plastic latches around the outside that will release as you pry.
Remove the LCD panel from the case and set them to the side.
Next you will need to unplug the 4 backlight power plugs as seen circled in yellow to the right. When re-assembling the monitor you can plug the plugs back into any the the sockets, there is not any polarity or voltage differences.
The part numbers on the board are as follows: C300, C203 and C206 are 1000uf 25volt and C208 and C209 are 1000uf 16volt. Be sure to install the new ones with the polarity stripe on the side going the same direction as the old ones come out.
