I've got a white dot and considering replacing the chip. However, Shopjimmy seems to be out of stock on almost every other part for this TV, including LED sources. I'm only going to be saving a few hundred dollars over a new TV, not sure I like the idea of being out of luck if another part fails that is unavailable. Looking for suggestions.
