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. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Magnavox 37MF231D 37" LCD TV "popped" now won't turn on at all!

Capacitors tend to pop when they fail. Phillips LCD TVs have lots of problems with capacitor failures in their power supplies. I've got my 37mf231d apart on my workbench as we speak. Mine makes a whistling sound which I believe is either a solder fault or a bad capacitor.

A new power supply board is about $150 for that TV. The gamble, of course, is if the power supply took out something else when it failed.
