I fixed it using two STK392-110 ic's I bought for $7 a piece from ebay. Remove the front plastic enclosure. You should see a wood access panel. The circuit board with the two ic's is located just inside the access panel. A piece of cake if you have the right tools (desolder and soldering equipment). I noticed the original ic's has a small drop of heat sink compound. This probably lessened the life of those ic's. I made sure I covered the whole back side with the stuff. My $1,000 + tv now works by replacing less than $20 worth of parts! I am glad I found this thread!!
