It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

Unplug unit and remove lower back panel should be 2 screws on each side and a few across the middle. Pull panel back and you should see a black box with metal folding handle. Remove the two left screws and pull out.
