My machine has had an LED failure rate similar to Taylor's. I have now lost 8 or 9 single LED boards and 4 of the large boards. This morning at least 7 of the LED emitters started displaying the wrong color so there must be at least one more bad board in the chain. The failures have definitely increased in frequency as in the first three months I only had two single boards die, but in the last month 7 small and 4 large have failed, including some of the replacement boards. I've decided to stop debugging and swapping bad LED boards until this fix is released. Pretty much every day now a new one dies. Unfortunately, my WOZ was built about a week too early (9/23/13) as it did not get the new 7v power supply and boards.

Looking forward to putting this LED mess in the past...
