Here's an update on the situation. I confirmed with Leviton they aren't repairing the LT boards anymore. I was able to find an almost identical LT board on ebay that was HAI branded already, for a good price. This time I had it flat on the table and was even more careful switching out the chips. There were no issues whatsoever changing them out. But the same thing happened. The board powered up before I changed the chip and afterwards it was dead. I put the old chip back in, still dead. So. What is happening here. There was no damage, nothing burned, melted or deformed, everything looks perfect. Also, I dismantled the old board and took a close look at it, there is no damage on it, it was just a shadow in the photo I think. I was told that the worst that could happen is the chip doesn't work and I could just replace the old chip but there is something else going on here. Any ideas?
