I replaced the bad STK ($20.00), replenished the thermal compound on the functioning STK (hate to replace a part that's still working) and swapped out the cooked resistors ($2.50). The TV now works like brand new and I have extra parts for the next time the STK IC's fry.
For what it's worth, I noticed the thermal compound (i.e. heatsink paste) was chalky and dry under the fried STK. My guess is this was what precipitated the STK going out.
