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.

Best thing to start here is open up the TV and look for any blown components on the power board (which is the one that has the power cable attached to); check the transformer for continuity first, that is the first thing to blow. Then go on with capacitors, resisters, and any burnt wires.
All of these parts are easy to find and replace, they can be found in local electronics shops.
Please post back how it went and any further information or questions you may have, so we can help you better.
