The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board.

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.

LG Plasma Problem
This could be the main drive board failed, or the plasma display backplane has a defect. These types of repairs are generaly fairly expensive.
I would be considering to get an estimate just in case it is simple fault. But, if the repair will cost more than a few hundred dollars, I would strongly suggest a new set. Also, servicing an older set is a gamble in case something else will soon fail.
Why red speckling around the border of the picture
try adjusting the voltages on the panel display, the voltages are listed on the label on the panel itself. Adjusting them up or down within 10 to 15 volts should affect that speckling around the picture, if not then the panel will most likely d to be replaced
