The TCON in this model is a common failure. Shopjimmy suggests replacing it with one of these models:

Per a post on this forum, I went with the second model because it has a chip that is different than the commonly failed one. TV works fine now although I did pay nearly $80 for the board. A repair service may be available for this board as well.
