Tried updating firmware in the blind several different ways with no luck, 3.3vdc is at 3.19vdc lower than the 1% tolerance of 3.26vdc. So maybe cap on power board. No obvious visual problems presenting themselves on any of the boards. Using TS Flow Chart points to possible SYSCON portion of the AV board. Just looking to refine my test results in...
